3) ION GPS 2001 MEETING BROCHURE READY TO BE MAILED

The ION GPS 2001 brochure is at the printer as of May 14 and will be in the mail by the end of the week! Give it a few weeks in the mail, especially if you live overseas. If you don't have your copy by June 15, email us at courses@navtechgps.com and we will check the status for you. In the meantime, the ION expects to have the conference and online registration on its website by June 1.

This is the largest GPS meeting in the world, with over 2000 attendees and about 100 exhibitors - be there for product releases and the most important GPS/GNSS technical papers of the year!

A note to Navtech's GPSetc Newsletter from the ION's webmaster:

"The ION GPS 2001 program will be available online at the ION website (www.ion.org) by Friday, May 18, 2001. After June 1, 2001 the title of each paper will be linked to the corresponding abstract. An electronic Book of Abstracts will also be available for download in PDF format.

This year ION is introducing a PDA version of the program (Palm, WinCE, Visor, Web Enabled Cellphones, etc). Registrants can download the program onto their handheld devices. Each time a user synchronizes, the latest program updates will be reflected on the PDA. Assuming registrants synchronize just prior to departing for the meeting, they will have a program that's more up-to-date than the on-site printed version.

All the links and information regarding GPS 2001 are on the ION website at www.ion.org/meetings.html 

Thank you,

Rick Buongiovanni, Information Manager, Institute of Navigation"

5) GPS 2 SOPS REPORT ON CONSTELLATION STATUS

"CLASSIFICATION: UNCLASSIFIED

The GPS Constellation Sustainment and Assessment Team (CSAT) met on 10 May in Los Angeles. This team of GPS Joint Program Office (JPO), 2d Space Operations Squadron (2 SOPS), and other U.S. Air Force and contractor representatives meets quarterly to assess the current status of the GPS constellation and make decisions regarding the sustainment of GPS. During the May 10 meeting, the CSAT cancelled the planned launch of SVN-45 (IIR-8) on 16 August 2001. The CSAT determined that the constellation health did not dictate an August launch. The CSAT is investigating moving the launch schedule for March 2002 into November 2001 if the need arises. Reducing the number of IIR launches now improves the chances of modifying more of the IIR satellites to include a second civil signal on L2 and M-Code on L1 and L2 A GPS IIR satellite is kept at Cape Canaveral at all times to support an emergency launch. An emergency launch is theoretically possible within 60-days of call-up. Of the 28 operational satellites, those that have exhibited performance problems have been positioned to minimize the impact of a failure. PRNs 15 and 17 (both in the D plane) have been positioned to cover each other in the event of a failure. If PRN 15 or 17 fails, 2 SOPS will request an emergency launch into the D plane. An emergency launch could also be requested in the event of an unexpected failure of a GPS satellite in a critical slot."

6) GPS CONSTELLATION STATUS - ERRATA

We had a misprint In our previous newsletter. Please note that PRN18 is actually SVN54, not SVN48 as we stated in the Constellation Status new item of our April 13 newsletter.

back to top

7) GLONASS STATUS REPORT

In summary, there are now 7 GLONASS satellites in orbit, a loss of one since our last newsletter of April 14. Satellite #781, Frequency 9, launched July 24, 1995, was set "unusable" on April 24, 2001. Of the remaining operating satellites, one was launched in 1995, three were launched in 1998 and three in 2000. The Federations' report is updated daily.

See http://mx.iki.rssi.ru/SFCSIC/english.html for GLONASS updates from the Russian Federation's Ministry of Defence.

8) HISTORY NOTE ON SELECTIVE AVAILABILITY

Selective Availability (SA) was turned off on May 2, 2000, providing the full accuracy of the GPS Standard Positioning Service (SPS) to users worldwide. So, for the past year, unaided accuracies have been determined by equipment, multipath, atmospheric conditions, etc., but are no longer affected by any intentional degradation of the signal by the US Department of Defense. Accuracies are surprisingly good (5 - 10 m.) with even the least expensive GPS units. The Technical Editor of this newsletter noted a marked improvement in his in-car nav system's ability to do its job well.

9) GNSS MEETING REPORT FROM SEVILLA, SPAIN

The meeting in Sevilla, Spain May 8-11, 2001 had over 530 delegates and over 20 exhibits, many of them quite large (the exhibits, not the delegates!). The technical focus of the meeting was the developmental Galileo system. Proceedings of the meeting will be available in 2-3 months and we will publish the contact information for that at a later date.

The meeting's social events were highlighted by lavish fireworks that were followed by a banquet, dancing, and a party that ended at 2 in the morning! Apparently, fun was had by all. The next GNSS meeting will be 27-30 May, 2002 in Copenhagen, Denmark.

back to top

10) GALILEO STATUS REPORT

This information collected by Mr. McDonald at the GNSS meeting in Sevilla, Spain May 8-11, 2001:

There was discussion of moving the operational date from 2008 forward by two years to 2006 by accelerating the program. The EU has a commitment of $100 million from participating governments, and an additional $100 million has been committed by industry. Further decision on full commitment to an operational system is currently planned for December, 2001. The current work is still developmental. It was repeatedly stated by various Europeans that Galileo should be viewed as an addition to GPS, not a competitor. They expect the first 30 satellite deployment of Galileo to cost about 3-4 billion Euros. (Euro = $.89 in May 2001)

Technical Editor's Note: A political comment made by Mr. Jac Spaans during the meeting was that while the US has made promises about sustaining GPS in a mode that is useful to the world, the US has broken promises, specifically the Koyoto Accord (regarding the environment), and cannot be relied upon. This thinking has been a motivator in developing the system, but it appears that parties from both the US and Europe feel that an additional system will create a powerful capability, not just a strong alternative.
