  • Microsoft and Nortel existing Alliance Roadmap

    information

    Microsoft and Nortel existing Alliance Roadmap
  • with the aid of Stuart J. Johnston
  • January 18, 2007
  • Six months after announcing a telecommunications alliance, Microsoft and Nortel this week introduced some early consequences of their efforts and outlined a roadmap for future initiatives.

    the two corporations first announced their collaboration final summer.

    The road map includes three new joint solutions “to dramatically enrich commerce communications by using breaking down the obstacles between voice, electronic mail, immediate messaging, multimedia conferencing and other forms of communication,” in accordance with a press release with the aid of the two companies.

    also covered within the announcement are 11 new implementation functions from Nortel and the opening of greater than 20 joint demonstration centers where consumers can sustain the technology, the commentary persevered.

    moreover, the two groups spoke of they acquire signed agreements with dozens of valued clientele, and acquire developed a “pipeline of hundreds of possibilities who wish to understand the advantages of unified communications.”

    From Microsoft's perspective, it is every solitary a Part of the company's long-time period play to merge every solitary kinds of communications and messaging into a solitary framework. A year in the past, the commerce announced that it became merging its change Server group with its real-Time Collaboration (RTC) group, and that it had begun to believe of both applied sciences comprising a "platform."

    the brand new neighborhood was named the Unified Communications community (UCG) and resides in Microsoft's company Division. The theory for the brand new group emanated from a imaginative and prescient of including continuity to a myriad of communications gadgets, technologies and modes -- from e-mail and rapid messaging to Voice over cyber web Protocol (VoIP), audio/video and net conferencing -- in a unified manner.

    The three new joint solutions announced by route of the alliance this week are named Unified Communications integrated department, Unified Messaging, and Conferencing.

    When it's obtainable in the fourth quarter, UC integrated fork will hold Nortel and Microsoft technology on a solitary piece of hardware that grants VoIP and unified communications in remote offices.

    Coming slightly earlier in the 2d quarter, Unified Messaging will purpose to simplify customer deployments, indigenous session initiation protocol (SIP) interoperability between the Nortel communication Server 1000 and Microsoft change Server 2007. The solution contains Nortel expert capabilities for design, deployment and assist.

    additionally coming within the fourth quarter, Conferencing will prolong Nortel Multimedia Conferencing to Microsoft office Communicator 2007. It goals to provide a solitary client journey constant throughout functions reminiscent of voice, rapid messaging, presence, and audio- and videoconferencing.

    This 12 months, the organizations besides blueprint to extend their present unified communications solution — a unified laptop and tender cell for VoIP, electronic mail, quick messaging and presence — to the Nortel conversation Server 2100, a carrier-grade commerce telephony product helping as much as 200,000 users on a solitary system, in keeping with enterprise statements.

    As for the highway map, both agencies acquire fitted greater than 20 joint demonstration facilities in North the united states, Europe and Asia, with more than one hundred further facilities scheduled to open with the aid of midyear.

    Nortel has besides added eleven core integration functions to champion customers construct, installation and succor joint unified communications options, together with end-to-conclusion challenge management. Nortel claims it has already skilled greater than 2,200 VoIP consultants to convey these capabilities and may add greater as deployment ramps up.

    about the writer

    Stuart J. Johnston has coated technology, specifically Microsoft, when you consider that February 1988 for InfoWorld, Computerworld, assistance Week, and workstation World, in addition to for commercial enterprise Developer, XML & net services, and .web magazines.


    Avaya lays out Nortel migration road map

    Avaya day after today will demonstrate a highway map that indicates how its valued clientele – in particular its newly minted Nortel shoppers -- can stream to unified communications technologies devoid of ripping out present equipment.

    Avaya the following day will exhibit a road map that indicates how its customers – in particular its newly minted Nortel clients -- can circulation to unified communications technologies without ripping out present gear.

    the surge and tumble of Nortel

    The blueprint exceptionally addresses how the commerce will eradicate overlap between its own and Nortel's product strains, every so often favoring Avaya expertise, once in a while Nortel's, in the areas of unified communications, contact centers, petite and midsize agencies as well as community infrastructure. on the equal time the blueprint allows for permeate savings by the exercise of SIP trunking so that it will let customers ship voice and information over one pipe in situation of distinct lines and different reduced charges through centralizing administration of corporate mobilephone systems, Avaya says.

    The net influence, says Alan Baratz, senior vp and president for world communique solutions at Avaya, is elevated capabilities, reduced costs and fewer disruptive change.

    Promising to achieve a mighty Part of this inside the year is an aggressive purpose that may besides stir Nortel consumers trying to find an attractive route to unified communications, says Zeus Kerravala, an analyst with the yankee community.

    Chart showing what products will  approach out of Avaya Nortel

    offering on time is captious as a result of former Nortel clients that are looking to aggressively pursue UC may not want to wait and wait, he says. Avaya CEO Kevin Kennedy's time at Cisco may assist because of that rival's journey in purchasing different groups and integrating them smoothly, he says.

    "each Nortel client goes to acquire a competitive vendor trying to create a course to their own unified communications answer," he says. Fumbling may not subsist fatal, Kerravala says, however might imply a loss of the remarkable 25% marketshare he says Avaya has gathered in telephony.

    As for the specifics of the street map, including an necessary SIP layer into the communications hierarchy should subsist completed via Avaya air of secrecy, the business's SIP-based verbal exchange application platform that may subsist sandwiched between communications infrastructure - such as PBXs - and features - equivalent to voice, video, messaging, conferencing and mobility.

    With charisma in area, legacy Avaya and Nortel PBXs will interoperate with SIP-based VoIP apparatus. So Nortel verbal exchange Server a thousand IP PBX with air of mystery layered on usurp of it might interface with SIP-based phones plugged into the air of mystery aspect of the network. every solitary the telephones would acquire CS one thousand points and the equal button sequencing as a route to navigate those aspects, Baratz says. also, legacy Nortel phones can subsist plugged into the air of secrecy aspect of the community.

    This trot will nick back can permeate of adopting unified communications since it reduces the necessity for replacing PBXs and telephones as well as the permeate of retraining conclusion clients in how new telephones work, he says.

    The blueprint requires application integration and it may not happen overnight, Baratz says, nonetheless it will subsist accomplished by means of the conclusion of this 12 months, seemingly in November, Baratz says. Nortel's commerce Communications gadget manager could subsist integrated into air of secrecy, as will Nortel's Agile Communications ambiance (ACE), which allows for infusing purposes with communications capabilities.

    The changes can subsist disbursed as software improvements to latest aura purchasers.

    This strategy isn't spectacular, Kerravala says, as a result of air of secrecy turned into designed to include an SIP-based mostly equipment, no depend who the supplier. Integration with Nortel gadget should soundless subsist simpler because Avaya owns both sets of belongings so can gain their SIP implementations appropriate. specifications-compliant implementations of SIP can vary enough that they don't interoperate, he notes.

    in the region of contact facilities, Avaya will strengthen Nortel Contact seat application and then combine it into its present line. Over the next six to 9 months, extra revisions of Nortel's Contact core will prepare it to eddy into the Avaya providing for midsize agencies instead of Contact middle express.

    After that, the contact core application from Nortel could subsist advanced to incorporate architectural points from both Nortel and Avaya strains, then extra developed to scale to enterprise proportions. These two revisions will capture six to nine months each. At that factor the utility will eddy into an upgrade to substitute Avaya's high-end Contact core Elite.

    Baratz says that even earlier than the acquisition of Nortel, Avaya stated that Nortel's midsize contact seat become more desirable. "It become very near the top-rated product they desired," he says.

    Avaya plans to slowly reduce the number of telephony alternatives purchasable for petite and midsize organisations. It plans to carry legacy Avaya partner and integral 5 key methods as well as Nortel Norstar programs below the umbrella of its IP office gear.

    IP workplace might subsist developed to aid Norstar techniques and Nortel enterprise Communications supervisor hybrid PBXs, and a number of years down the line will substitute them. but in the meantime, Norstar and BCM will continue to subsist available. "Nothing abrupt goes to ensue here," Baratz says.

    Nortel's application Communications gadget SIP appliance will connect the portfolio as is. There isn't any analogous Avaya product.

    Nortel brought along a portfolio of switches, community security and wireless gear for which Avaya has no competing equipment. Avaya plans to sell these products and boost them to interoperate more closely with its unified communications infrastructure, Baratz says.

    as an example, the instant gear and switches can besides subsist tweaked to give extra complete facts concerning the presence of cellular workers. at present they exhibit even if a person is available by means of voice. With enhanced integration they may swear that the particular person is purchasable on a cellular device and the situation it's discovered, he says.

    however Kerravala says that Avaya needs to boost its gear to subsist aggressive with other infrastructure providers characteristic for characteristic, now not simply to acquire switches and routers that expand communications. He says Avaya owns 5% of the infrastructure market by using handicap of buying Nortel and may let it operate as a divorce division at once taking on Cisco, HP and others. "or not it's a great attach in base," he says.

    First look: VMware vSphere 6 keeps its edge

    In the not so far-off past, VMware held a long and commanding lead in the server virtualization space, offering core features that were simply unmatched by the competition. In the past few years, however, competition in virtualization has been fierce, the competitors acquire drawn near, and VMware has been left with fewer ways to distinguish itself.

    The competition may acquire grown over the years, and VMware may not savor quite as great a lead as it once did -- but it soundless enjoys a lead. With useful improvements to a number of key features, as well as the bundling of functions such as backup and recovery that were previously available separately, vSphere 6 is a worthy addition to the vSphere line. That said, some of the major advances in this version, such as long-distance vMotion, will matter most to larger vSphere shops.

    Big changes in vSphere 6

    The mighty changes in vSphere 6 revolve around expanded resource limits, enhanced vMotion capabilities, a more complete version of the Linux-based vCenter Server Appliance, storage offloading, and enhancements to the Web client. In addition, VMware has bundled extra technologies into vSphere 6, such as the vCenter Director content library that is used to store ISO images, templates, scripts, OVF files, and other elements, and to automatically divide them across multiple vCenter servers. The Data Protection Advanced backup and recovery tools are now included as well.

    VMware vSphere 6 offers advances in the previously existing frailty Tolerance feature. frailty Tolerance is the technology by which a solitary VM can acquire presence on multiple physical servers simultaneously. Should the physical server running the energetic instance fail, the secondary instance is immediately activated. Without frailty Tolerance, the VM could subsist automatically restarted on another host, but would require time to detect the failure and boot on the new host. With frailty Tolerance, that step is avoided.

    In previous versions of vSphere, frailty Tolerance supported only a solitary vCPU per VM and four fault-tolerant VMs per host. In vSphere 6, the limits are now four vCPUs per VM and either eight vCPUs or four VMs per host.

    VMware vSphere 6 Web client

    The main screen of the new vSphere Web Client looks much more dote the Windows client than in previous versions. Note the Recent Tasks window at the bottom.

    Long-distance vMotion

    The vMotion improvements will subsist more germane to those with multiple data centers spread over wide geographic areas. Prior to vSphere 6, live-migrating VMs over great distances was problematic and required elevated bandwidth and low-latency connections to succeed. In vSphere 6, the network tolerances acquire been extended, and vMotions can now subsist completed over links with 100ms latency or less, requiring 250 megabits of bandwidth per vMotion.

    In addition, VMs can subsist vMotioned between vCenter servers, and with a proper underlying infrastructure, vMotions can subsist completed without common shared storage. There are restrictions that approach with these expanded capabilities, mostly in the profile of proper network layouts at each side to allow for proper communication of the VMs on each network.

    The ESXi 6.0 hypervisor in vSphere 6 can ply up to 64 physical hosts per cluster, up from 32 hosts, and each instance can now champion up to 480 CPUs, 12TB of RAM, and 1,000 VMs. Each VM can now subsist precipitate with up to 128 vCPUs and 4TB of RAM, with vNUMA hot-add reminiscence capabilities.

    VMware vCenter Server improvements

    On the management side, the vCenter Server Appliance is now feature-complete, on par with its Windows counterpart. Previously, you could precipitate the Linux-based vCenter Server Appliance and manage ESXi hosts, but some of the more advanced features (notably Update Manager) of the Windows-based vCenter Server were not available. As of vSphere 6, the appliance can ply every solitary the tasks that a Windows installation can. This is significant word to those who prefer to not manage a Windows server to precipitate vCenter.

    Those who precipitate vCenter Server on Windows will notice that the installation procedure is simplified, though it takes quite a while to complete. every solitary of the moving parts that gain up vCenter Server are installed in a solitary installer action now, including the new Platform Services Controller, which handles SSO, licensing, and certificate management. vCenter Server can subsist deployed with every solitary components on a solitary system, or it can subsist split across multiple systems with the Platform Services Controller and vCenter Server installed separately.

    Both vCenter Server for Windows and the vCenter Server Appliance now exercise a local PostgreSQL database by default, though external Microsoft SQL Server and Oracle databases are besides supported on Windows and Oracle databases on the appliance. The switch to PostgreSQL will subsist necessary to those running with local databases on earlier versions of vSphere due to the fact that the limitations of the previous Microsoft database are no longer present; thus, local databases can now champion 1,000 hosts and 10,000 VMs.

    VMware vSphere 6 Web client menus

    The vSphere Web Client's right-click context menus are soundless sluggish at times, but overall faster than before. 

    A better Web UI

    The first version of the vSphere Web Client was slow, incomplete, and not nearly as fluid as the Windows client, and many users simply refused to work with it. In vSphere 5.5, they saw improvements to the Web client, but it soundless wasn’t quite to the level of the stand-alone client. In vSphere 6, further usability and precipitate improvements gain the Web client more palatable, as does the addition of champion for a broader sweep of client browsers and operating systems. The client integration tools that allow for necessary features dote VM console access are now available for more platforms, including Mac OS X.

    Users of the Web UI will note that it bears a stronger resemblance to the stand-alone client, including the recent tasks pane at the bottom that displays what actions acquire been taken within the infrastructure. Further, the context menus available via right-click are better laid out, and the overall navigation in the Web client is better than the previous iterations.

    The success of the Web client is crucial to VMware. The company has been warning about the impending demise of the stand-alone client for several releases and currently stresses that using the stand-alone client will restrict the functionality of vSphere to vSphere 5.0 levels. Features and enhancements from vSphere 5.5 onward are simply not available in the Windows client.

    VMware vSphere 6 new VM

    Creating a new VM in vSphere 6 using the vSphere Web Client.

    VMware Virtual Volumes

    VMware introduces a new storage integration concept with vSphere 6 called Virtual Volumes. This is essentially tighter integration with SAN and NAS devices to manage storage operations at the virtual disk level. Virtual Volumes are designed to eradicate the necessity to carve out great numbers of LUNs or volumes for virtualization hosts and to offload storage-related operations to compatible arrays, with granularity at the virtual disk level.

    This integration includes vSphere Storage Policy Based Management, which uses VMware’s storage API to communicate with storage arrays and connects the administration of VMs and storage through to the vSphere UI. Thus, policies can subsist created and applied to VMs through vCenter while related functions are performed natively by the arrays.

    VMware now includes vSphere Data Protection with vSphere Essentials Plus and higher editions of vSphere 6. This is a VM backup and recovery instrument that was previously known as vSphere Data Protection Advanced, a divorce option. This instrument can subsist used to provide application-aware VM backup and restoration, including champion for Microsoft SQL Server, Microsoft Exchange down to the mailbox level, and other well-liked databases and applications.

    Up from vSphere 5.5

    With vSphere 6, VMware offers a collection of welcome features that are now bundled in rather than divorce products, advances a number of pre-existing features, and streamlines the installation process. The Web client may soundless cause more than a few grumbles from those who acquire been using the stand-alone client from the beginning, but it’s significantly better than in previous iterations.

    The advances in vMotion and other cross-site features are of limited exercise to shops not running multiple interconnected data centers with enough dedicated bandwidth to champion those features. But as VMware increases the tolerances to lower bandwidth and higher latency, the viability of introducing such features grows.

    There’s no mistaking the fact that VMware continues to hold the leadership role in server virtualization, but as the feature sets of the top vendors continue to converge and competing solutions continue to accumulate more robust, they may contemplate more of this feature bundling and simplified licensing in the future. For now, vSphere 6 maintains its situation as the cream of the crop.


    Innovation: EGNOS in Northeastern Europe

    We examine the performance of EGNOS in Finland, which lies near the northeast periphery of the coverage area, and how this performance can subsist improved now and in the future.

    By Mohammad Zahidul H. Bhuiyan, Heidi Kuusniemi, Auryn Soderini, Salomon Honkala and Simo Marila

    INNOVATION INSIGHTS with Richard Langley

    “[O]NE ORBIT, WITH A RADIUS OF 42,000 KM, has a period of exactly 24 hours. A body in such an orbit, if its plane coincided with that of the earth’s equator, would revolve with the earth and would thus subsist stationary above the identical spot on the planet. … [A] transmission received from any point on the hemisphere could subsist broadcast to the all of the visible mug of the globe, and thus the requirements of every solitary feasible services would subsist met.” So wrote writer and futurist Arthur C. Clarke in his October 1945 Wireless World article “Extra-terrestrial Relays: Can Rocket Stations Give World-wide Radio Coverage?,” envisaging the geostationary orbit (GEO) communication satellite.

    The first GEO satellite was Syncom III, orbited by the United States in August 1964. Since then, more than 1,000 satellites acquire been launched into what is known as the Clarke Belt and around 450 are presently active. Most of them are used for civil or military communication. Some are used for direct-to-user TV and radio. Some are used for weather monitoring and other kinds of surveillance. And some are used for augmenting GPS.

    While GPS is a remarkable positioning system, its real-time accuracy using L1-frequency pseudorange measurements and its instantaneous integrity are not enough for some applications such as aircraft navigation. That is why the U.S. Federal Aviation Administration developed the Wide region Augmentation System (WAAS), the first satellite-based augmentation system (SBAS). WAAS provides differential correction data and integrity information to GPS users in existent time throughout most of North America using a “bent pipe” from a ground station through the GEO satellite to a user’s equipment. It uses a state-space-domain correction approach, which provides corrections for the satellite orbit and clock data transmitted by GPS satellites along with ionospheric propagation delays, every solitary computed from measurements collected by a continent-wide tracking network.

    The WAAS concept has been duplicated for other regions. Three other SBASs are in full operation: the European Geostationary Navigation Overlay Service (EGNOS), Japan’s Multifunctional Transport Satellite Satellite-based Augmentation System, and India’s GPS-aided GEO Augmented Navigation System. Russia’s System for Differential Correction and Monitoring is currently in development.

    One hitch with GEO satellites whatever their office is their inability to service elevated latitudes well. At a latitude of 65°, a GEO satellite has an altitude angle of only around 17° at most and at 75°, it’s about 6° or less. Even if a GEO satellite is above the local horizon, communication might subsist difficult due to the longer signal path length between the satellite and the user.

    And so it is with GEO satellites used for SBAS at elevated latitudes. And there is an additional problem that even if the signals from an SBAS satellite can subsist received, corrections for some GPS satellites will not subsist received if they are outside the coverage region of the SBAS tracking network. In this month’s column, they examine the performance of EGNOS in Finland, which lies near the northeast periphery of the EGNOS coverage area, and how this performance can subsist improved now and in the future.

    FIGURE 1. Finnish national GNSS network, FinnRef. The three stations highlighted in red had the worst positioning accuracy in their analyses.

    The European Geostationary Navigation Overlay Service (EGNOS) is the first European-operated satellite navigation system and is a precursor to Galileo, Europe’s independent global navigation satellite system (GNSS), now being deployed. EGNOS, as a satellite-based augmentation system (SBAS) similar to the U.S. Wide region Augmentation System (WAAS), was developed with the vision to ameliorate the performance of GNSSs, such as GPS and Galileo. At the moment, EGNOS only augments GPS, making it suitable for safety-critical applications such as flying aircraft or navigating ships through narrow channels.

    Additionally, EGNOS besides supports new applications in many different sectors, such as agriculture (for high-precision spraying of fertilizers), transport (enabling automatic road-tolling or pay-per-use insurance schemes) or even precise personal navigation services for universal and specific use.

    At present, there are two operational geostationary Earth orbiting (GEO) satellites and until March 2017, these satellites had pseudorandom noise code (PRN) numbers 120 and 136 that simultaneously broadcast EGNOS correction messages to European GPS users. The PRN satellites 120 and 136 are located at 15.5°W and 5.0°E. (Since March, PRN 123 has replaced PRN 136 as one of the operational EGNOS satellites.) The exercise of EGNOS in the northern Europe is much more challenging than elsewhere in Europe due to the relatively low-elevation angle of some EGNOS satellites as seen from there of about 14° or less.

    To ameliorate their understanding of the privilege performance of EGNOS in Finnish territory, they recently carried out a project entitled “Finland’s EGNOS Monitoring and Performance Evaluation (FEGNOS).” At the northeastern edge of the EGNOS coverage area, the availability of the EGNOS geostationary satellites is compromised due to their low-elevation angles. The Finnish Geospatial Research Institute (FGI) at the National Land Survey of Finland (NLS) maintains a network of 20 permanent GNSS reference stations (FinnRef) every solitary over Finland. The core objective of the FEGNOS project is to evaluate the performance of EGNOS at every solitary of those reference stations to determine if the EGNOS system performance reaches its target in Finland.

    Building on their initial research, in this article they report on the analysis of EGNOS performance at every solitary 20 FinnRef stations for a year-long time-frame from November 2015 until October 2016. As it is of minute to compare the performance of EGNOS in a geographic region where EGNOS satellite visibility can subsist impecunious due to low-elevation angle, they assessed the performance of EGNOS by comparing the receivers’ own decoded SBAS messages against the SBAS messages provided by the EGNOS Data Access Service (EDAS). The daily EDAS SBAS messages can subsist freely downloaded from the EDAS server with prior authentication from EDAS. The performance analysis has been carried out for the following three cases:

  • Applying EGNOS corrections obtained from the EDAS server
  • Applying EGNOS corrections obtained from the receiver-decoded (Rx-decoded) EGNOS messages
  • GPS stand-alone solution without any EGNOS corrections.
  • We carried out the data analysis using the EGNOS analyzing instrument called PEGASUS (which originally stood for Prototype EGNOS Analysis Using SAPPHIRE, where SAPPHIRE stands for Satellite and Aircraft Database Programme for System Integrity Research) from Eurocontrol. The results complicated that the Rx-decoded EGNOS performance is not as honorable as the performance obtained from the EDAS-offered message corrections. The ongoing sustain and erudition learned from the project has helped to identify weaknesses of the EGNOS system at elevated northern latitudes.

    FINNISH NATIONAL GNSS NETWORK, FINNREF

    The Finnish National GNSS network, FinnRef, was established on the initiative of the Nordic Geodetic Commission and the director generals of the Nordic Mapping Authorities in the 1990s. FinnRef is Part of the Nordic GNSS network, and some stations of the FinnRef network besides contribute to the global International GNSS Service (IGS) network and to the European Permanent Network (EPN). The primary office of FinnRef is to tender geodetic-grade GNSS measurements, which acquire been continuously used for forming and maintaining the national coordinate system (EUREF-FIN). In addition, the FinnRef network is used for many GNSS-related research activities. For example, it is now feasible to resolve the positioning performance of different augmentation services via the FinnRef network. Currently, FinnRef besides offers an open positioning service based on the differential GNSS (DGNSS) corrections for GPS and GLONASS.

    The FinnRef network was renewed during the 2012–2013 timeframe. The renewed FinnRef network now consists of 20 GNSS reference stations, as shown in device 1. The raw GNSS data from every solitary 20 reference stations is used in the FEGNOS project for EGNOS performance monitoring and analysis.

    DATA COLLECTION

    EGNOS signal monitoring at every solitary FinnRef stations was carried out for one year from Nov. 4, 2015, until Oct. 31, 2016. There are in total about 360 days of data from the 20 stations out of a feasible 366 days (2016 was a leap year). The day-of-year (DOY) information for the collected data set is detailed in TABLE 1. No data was available during DOY 233 and 234 of 2016 due to a technical frailty at the FinnRef stations. There are 57 days of data from the year 2015 and 303 days of data from 2016.

    Table 1. DOY information for the year-long data set.

    Each FinnRef station is equipped with a dual-frequency geodetic-grade receiver. Each receiver generates 1-hour binary proprietary data files with a 1-Hz data rate. Data is pushed to the network server and saved at the conclusion of each hour. This means that there are in total 24 data sets for each solitary day for one solitary station. every solitary the stations’ binary data files are then organized under one directory, which is named after DOY for that particular year. The FEGNOS data Collection instrument (FEGCoT) was developed in Matlab to collect data every day automatically from every solitary 20 FinnRef stations.

    These three steps are followed for automatic data collection:

  • Collect: 1-Hz hourly data is collected from the FinnRef server, and then saved to the local arduous disk for further processing.
  • Convert: The saved raw binary-formatted hourly data files from the receivers are converted to RINEX observation, navigation and SBAS data files via the receiver manufacturer’s converter.
  • Combine: In this step, every solitary 24 one-hour data sets from each station are combined into one solitary 24-hour data set for every RINEX file type (that is, observation, navigation and SBAS files).
  • The combined 24-hour RINEX data file for each station is then processed using the PEGASUS software. The key configuration parameters used in the data analysis are listed in TABLE 2. (Note that airborne accuracy designator refers to specifications in the WAAS Minimum Operational Performance Standards,  MOPS.)

    TABLE 2. PEGASUS configuration parameters.

    Two PEGASUS modules are used for data analysis:

  • Convertor module: The Convertor module translates the RINEX observation, navigation and SBAS data into a generic format, which can then subsist used by the GNSS_Solution module for detailed analysis. Convertor can besides exercise input from different GNSS/SBAS receivers and then transform the recorded binary data into readable ASCII data.
  • GNSS_Solution module: The GNSS_Solution module is used to compute a position solution in conformance with the MOPS for GNSS receivers used in avionics (GPS, SBAS or ground-based augmentation systems). In other words, the GNSS_Solution module can subsist considered as a post-processing MOPS-compliant GNSS receiver. It interfaces with other PEGASUS components, notably the Convertor module.
  • The altitude cut-off angle and the minimum accepted signal-to-noise ratio are kept low so as to acquire more satellites available for user-position computation. (The European Global Navigation Satellite Systems Agency (GSA) advises that sweep measurements from EGNOS satellites not subsist used for position computation.)

    A Matlab-script was written to download EDAS-provided daily SBAS messages automatically from the EDAS server. every solitary the PEGASUS-related processing was besides executed by a Matlab-based script.

    ANALYSIS OF RESULTS

    We analyzed the EGNOS/GPS performance for the above-mentioned cases with the collected year-long data set from the 20 FinnRef stations. The operational time or uptime of each FinnRef station was monitored throughout the FinnRef network nodes on a daily basis. The mediocre uptime of each station for the one-year data set is shown in device 2. The “b” in station names indicates one of the two data streams available from each station. The device shows that most of the stations were up for more than 98% of the time, while only few acquire uptimes close to 95%.

    FIGURE 2. Station uptime for every solitary FinnRef stations for the year-long data set.

    According to EGNOS Open Service (OS) horizontal and vertical accuracy requirements, the 95% Horizontal Navigation System oversight (HNSE) should subsist less than 3 meters, and the 95% vertical Navigation System oversight (VNSE) should subsist less than 4 meters in the EGNOS service provision area. The horizontal and vertical position errors at a defined time epoch are computed as the unlikeness between the estimated navigation position and the actual position in horizontal and vertical planes, respectively. The HNSE (95%) and VNSE (95%) were computed for every solitary FinnRef stations with the year-long data set.

    The yearly EGNOS performance in terms of HNSE (95%) and VNSE (95%) are shown in FIGURES 3 and 4, respectively. It can subsist observed that GPS+EGNOS offers significant accuracy improvement compared to GPS stand-alone solutions for every solitary of the stations. vertical accuracy improvement for EGNOS is greater than the horizontal improvement, mostly due to the better mitigation of ionospheric oversight compared to stand-alone GPS. They besides observed that the Rx-decoded EGNOS performance is not as honorable as the performance when corrections are obtained from the EDAS server. This might subsist due to the impecunious visibility of the EGNOS satellites at northeastern latitudes, which resulted in data aging or partial data loss of EGNOS messages.

    FIGURE 3. HNSE (95%) for every solitary FinnRef stations.

    FIGURE 4. VNSE (95%) for every solitary FinnRef stations.

    In FIGURES 5 and 6, the daily EGNOS performance in terms of VNSE (95%) are shown for the two cases: 1) applying EGNOS corrections from EDAS-provided EGNOS messages, and 2) applying EGNOS corrections from Rx-decoded EGNOS messages, respectively.

    FIGURE 5. VNSE (95%) performance over time with GPS+EGNOS (EDAS) corrections.

    FIGURE 6. VNSE (95%) performance over time with GPS+EGNOS (Rx-decoded) corrections.

    For a better understanding, the percentage of EGNOS OS requirement failure when analyzed on a daily basis with EDAS offered corrections is presented in device 7.

    FIGURE 7. Percent of EGNOS OS requirement failure with EDAS-provided EGNOS correction messages.

    The percentage of EGNOS OS requirement failure was computed from the number of days where the HNSE (95%) ≥3 meters in the case of horizontal navigation solution oversight and VNSE (95%) ≥ 4 meters in the case of vertical navigation solution error. As observed from Figures 5 and 7, the EDAS offered EGNOS corrections fail to meet the OS requirement only in a few instances. Similarly, the percentage of EGNOS OS requirement failure when analyzed on a daily basis with Rx-decoded corrections is presented in device 8. It can subsist easily seen from Figures 6 and 8 that the Rx-decoded EGNOS performance fails to meet the OS requirement in many instances. However, the daily fluctuations are averaged out when the year-long data is taken into account, providing satisfactory performance on the whole.

    FIGURE 8. Percent of EGNOS OS requirement failure with Rx-Decoded EGNOS correction messages.

    The yearly EGNOS performance in terms of VNSE (99%) is shown in device 9.

    FIGURE 9. Sorted VNSE (99%) performance with GPS+EGNOS (EDAS) corrections for every solitary FinnRef stations.

    The three stations with the worst accuracy are highlighted in red in device 1. These stations are located on the northeastern rim of the EGNOS coverage area. The EGNOS User Differential sweep oversight Indicator (UDREI) device for three stations (FINb, VIRb, and SAVb) is shown in device 10(a), 10(b) and 10(c), respectively.

    FIGURE 10. EGNOS UDREI as seen at (a) FINb, (b) VIRb and (c) SAVb.

    The stations were chosen so that they portray a wide geographical spread over Finland. According to device 10, the satellite UDREI values are in the sweep of 14 and 15 (marked as blue) at the northeastern edge of the sky plot. A UDREI of 14 indicates “not monitored” and 15 indicates “do not use” for a particular satellite. Even though the satellites had a qualify altitude angle with respect to the user, the EGNOS system was unable to tender corrections to those satellites in the northeastern sky. Relatively lower availability of GPS satellites coupled with the lower number of EGNOS Ranging and Integrity Monitoring Stations (RIMS) at northeastern latitudes contributed to the poorer than expected positioning performance in the northeastern coverage region of EGNOS.

    CONCLUSIONS

    In this article, they presented a summary of an analysis of EGNOS in Finland for a year-long period, and they explained their automated data collection and data analysis procedure. The following key observations can subsist made based on the analysis of the year-long data set:

  • The exercise of EGNOS significantly improves the positioning performance compared to GPS stand-alone operation.
  • The vertical accuracy improvement for EGNOS is higher than the horizontal improvement compared to GPS stand-alone performance.
  • The performance of EGNOS with the receivers’ own decoded message corrections is not as honorable as the performance obtained through EDAS-provided EGNOS corrections.
  • EGNOS does not tender corrections for those GPS satellites that are setting in the northeastern sky of the EGNOS coverage area.
  • The percentage of EGNOS OS requirement failure when analyzed on a daily basis with Rx-decoded corrections is significant. This is mostly due to the impecunious visibility of GEO satellites from northeastern latitudes.
  • These findings emphasize the fact that there is a mighty necessity at northeastern latitudes for an alternative solution to the GEO satellites broadcasting EGNOS corrections. The existing alternative solution is to download the corrections from the Internet through EDAS at the cost of an additional communication link. The other feasible alternative could subsist to broadcast corrections via inclined geosynchronous orbit satellites, or by some other means.

    IP PBXs Unwrapped

    As businesses hunt to migrate to IP-based telephony solutions, introductions of unadulterated IP and converged systems are on the rise, according to the latest research. Database publisher and analyst group TelecomTactics finds that unadulterated IP systems and converged systems portray a combined 70 percent of new system introductions in 2004 compared to only 35 percent in 2000. Traditional telephone systems that can subsist IP-enabled or those with no champion for VoIP are on the decline.

    Businesses are moving to capture handicap of IP-based solutions, but protection of their current gear investment remains a priority. The goal is to avoid elevated costs by retaining and reusing existing line and station cards and telephones on a new IP system. Converged systems that champion both packet and circuit switching are a honorable suitable since these systems accommodate connection to analog and digital telephones, as well as newer IP devices. In 2002, the enterprise telephony market experienced a surge in introductions of converged systems by Avaya, Mitel Networks, NEC, Siemens and other manufacturers.

    Pure IP platforms utilize IP peer-to-peer switching, connecting stations directly to each other through the IP network, but can incorporate optional gateways or interfaces for traditional analog and digital connections.

    IP networking benefits businesses with distributed locations and makes it more cost-effective to include petite fork offices in a network. In 2004, a number of manufacturers introduced unadulterated IP platforms, including 3Com, Comdial and Toshiba with petite and mid-sized offerings, and Cisco, NEC and Nortel Networks with platforms for larger enterprises (see system profiles).

    Businesses benefit from new IP-based employee productivity applications, including instant messaging, presence, IP audio and video conferencing and collaboration. Collaborative applications succor to reduce travel and facilitate communication among dispersed workgroups, allowing employees to easily share information from any location on a corporate network. Web-based conferencing lets conferees record presentations and exercise white-boarding or engage in face-to- mug video calls. Presence-based communication improves employee and customer interactions, allowing users to define how they wish to subsist reached (via desk phone, cell phone, e-mail, instant messaging or other media). New sophisticated, IP-based contact seat functionality adds agent/supervisor instant messaging, collaborative Web browsing, e-mail automated response, live Web chat and multimedia queuing/routing to title a few.

    Further studies complicated that champion for IP telephones on commerce telephony platforms continues to surge from only 20 percent in 1999 to more than 80 percent in 2004. Leading manufacturers are rounding out their IP phone portfolios, offering a sweep of choices from cost-effective, entry-level and mid-range phones to advanced models. By transmitting voice over a companys data network, IP telephones can reduce costs and easily extend office telephone features to a remote location such as a home or fork office. Corporate directory access, call-history logging, conversation record, great pixel-based displays, color touch-screens and even interoperability with a PDA are among the many well-liked IP telephone features.
