SOFTWARE USED: GPSOBS/BAHN5 2. MODELS AND CONSTANTS USED a) General: no changes with respect to previous runs b) Satellite Force Model: no changes with respect to previous runs The following table gives an overview over the satellites that have been used for the different one-day-arc solutions: '+' used, '-' not used. __________________________________________________________________________ PRN02| 03| 11| 12| 13| 14| 15| 16| 17| 18| 19| 20| 21| 23| 24| 25| 26| 28| ____-|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| DAY| | | | | | | | | | | | | | | | | | | 194|+| + | + | + | + | + | + | + | + | + | + | + | + | + | + | + | | + | 195|+| + | + | + | + | + | + | + | + | + | + | + | + | + | + | + | | + | 196|+| + | + | + | + | + | + | + | + | + | + | + | + | + | - | + | | + | 197|+| + | + | + | + | + | + | + | + | + | + | + | - | + | + | - | | + | 198|+| + | + | + | + | + | + | + | + | + | + | + | + | + | + | + | | + | 199|+| + | + | + | + | + | + | + | + | + | + | + | + | + | + | + | | + | 200|+| + | + | + | + | + | + | + | + | + | + | + | + | + | + | + | | + | c) Ground Stations (if being estimated, one position (X,Y,Z) every day): The following table gives an overview over the ground stations, that have been included into the GPS-data processing at ESOC. Except where otherwise noted ("remarks"), corrections are taken from IGS Mail No. 33 - IGS site information and coordinates - (Boucher and Altamimi). __________________________________________________________________________ | | | GPS WEEK 653 | | | | 1 1 1 1 1 1 2 | | | | 9 9 9 9 9 9 0 | SITE | COUNTRY |CODE| 4 5 6 7 8 9 0 | REMARKS --------------------|-------------|----|---------------------|------------ Algonquin | Canada |ALGO| F F F F F F F | CANB/Tidbinbilla | Australia |TIDB| E E E E E ----- | Bern Penticton | U.S.A. |DRAO| E E E E E E E | Fairbanks | U.S.A/Alaska|FAIR| F F F F F F F | Goldstone | U.S.A. |GOLD| E E E E E E E | Herstmonceux | U.K. |HERS| ------------------- | Kokee Park | U.S.A/Hawaii|KOKB| E E E E E E E | Kourou (ESA) | French Guyan|KOUR| ------------------- | Madrid | Spain |MADR| F F F F F F F | Maspalomas (ESA) | Spain/Can.Is|MASP| E E E E E E E | Matera | Italy |MATE| ----- E ----------- | McMurdo | Antarctica |MCMU| E E E E E E E | IGS Mail 44 Metsahovi | Finland |METS| ------------------- | Ny Alesund/Spitzb.| Norway |NYAL| ----- E ----------- | Onsala | Norway |ONSA| ------------------- | Pamate/Tahiti | France |PAMA| E E E E E E E | IGS Mail 44 Santiago | Chile |SANT| ------------------- | IGS Mail 35 Tai-Shi | Taiwan |TAIW| ----- E ----------- | Bern Tromsoe | Norway |TROM| ------------------- | Usuda | Japan |USUD| E E E E -------- | Wettzell | Germany |WETB| ----- E ----------- | Yaragadee | Australia |YAR1| F F F F F F F | Yellowknife | Canada |YELL| F F F F F F F | with: "F" ... coordinates of ground station kept fixed, "E" ... coordinates of ground station estimated, "-" ... ground station not included on that day. In the case of Canberra and Ny Alesund, the 4-Char ID's have changed: CANB ===> TIDB (Tidbinbilla) NALL ===> NYAL (Ny Alesund) d) Earth Rotation Parameters: no changes with respect to previous runs e) Observations: no changes with respect to previous runs 3. PARAMETERS TO BE ESTIMATED PER 1-DAY ARC a) Satellite Parameters per Spacecraft: no changes with respect to previous runs b) Station related parameters per ground station: no changes with respect to previous runs c) Earth Rotation Parameters: no changes with respect to previous runs 4. PARAMETERS TO BE KEPT FIXED IN THE SOLUTION a) Satellite Parameters per Spacecraft: no changes with respect to previous runs b) Station related parameters per Ground Station: no changes with respect to previous runs 5.
