It seems that after a gradual start the IGSLEO project is now making great strides. CHAMP orbit comparisons are now posted to the world http://nng.esoc.esa.de/gps/campaign.html/> and http://nng.esoc.esa.de/gps/slr.html/>, (though there are still several holdouts among you), SAC-C and Jason-1 are functioning smoothly, and GRACE is approaching a March launch. Together these will give us five geodetic flight receivers to work/play with, four of them providing occultation as well as POD data. This appears to be the dawn of the long-awaited age of geodetic flight GPS. The real challenge is not POD, though that provides a nice limbering-up exercise; rather, the real challenge is to integrate GPS LEO data into the full mix of IGS geodetic products, providing (possibly) improved GPS orbits and other geodetic products. That will become a major focus over the next year. I believe most of you will be attending the CHAMP Science Team meeting in Postdam later this month. That will provide an excellent venue for a most timely meeting of the IGSLEO pilot project. We may need 3-4 hours to cover the agenda. I would suggest Tuesday afternoon, Jan 22, as a possible meeting time. That overlaps a poster session and group meetings on Magnetics, but it may offer the least conflict for LEO interests. If you have an alternative proposal, please pass it along. Here are some proposed agenda items: 1. Brief mission recap: CHAMP, SAC-C, Jason-1, GRACE (Yunck) 2. CHAMP POD analysis overview (Boomkamp) 3. Brief CHAMP POD analysis reports (GFZ, JPL, ESA, NCL, AIUB, CSR, CNES, UNB, ASI, DEOS, TUM) 4. Data access and archives & network support (Neilan et al) 5. Station operations - reports and issues (TBD) 6. Hot issues in POD: bias fixing, integrated data analysis (Rothacher et al) 7. Extending the campaign to SAC-C, Jason-1, and GRACE (All) 8. Towards operational IGS POD products - a Pilot service? (All) 9. Integration of LEO data into traditional IGS products (All) 10. Plans for next meeting (All) Please respond with your: -- availability for a Jan 22 afternoon (2-6 pm) meeting in Potsdam -- suggested alternative times -- proposed agenda modifications. Thanks to all. Tom T. P. Yunck Ph: 818-354-3369 JPL, M/S 238-540 Fax: 818-393-6686 4800 Oak Grove Drive e-mail: tom.yunck@jpl.nasa.gov Pasadena, CA 91109
