Six initial conditions and nine radiation pressure para- meters per satellite were determined. No pseudo-stochastic pulses have been introduced up to now. - So far only receivers providing dual frequency GPS and GLONASS or dual fre- quency GLONASS measurements were included in the solution. - The daily orbit results stem from the middle day of a 5-day arc. - The satellite clock values included in the precise orbit files are broadcast clock values for the GLONASS satellites (no improvement done so far) and precise CODE estimates for the GPS satellites. - The following sites are constrained to their ITRF97 coordinates: - KR0G 10422M001 (Kiruna, Sweden) - METZ 10503M005 (Metsahovi, Finland) - OS0G 10402M004 (Onsala, Sweden) - SUNM 50143M001 (Brisbane, Australia) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1043N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10437.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 2 92 343108 9559 1.2 3 94 358976 10002 1.2 4 102 387754 10518 1.2 5 106 390005 10352 1.2 6 107 400597 10338 1.2 7 104 400575 10237 1.2 8 105 406713 10035 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109 111 113 115 116 122E ------------------------------------------------------------------------------- 2 5 7 6 9 7 18 12 5 12 3 6 5 9 8 6 11 10 4 8 4 4 3 6 7 5 16 9 3 4 5 4 7 5 6 6 12 11 5 7 6 4 4 4 9 5 16 8 -- 5 7 5 6 4 4 5 19 18 -- 3 8 4 4 4 4 5 13 23 -- 7 ------------------------------------------------------------------------------- ALL 4 5 6 7 6 15 14 4 7 ------------------------------------------------------------------------------- Remark: These RMS values may be too optimistic, because we fit the middle days of 5-day arcs with a 7-day arc. ------------------------------------------------------------------------------- WEEKLY COORDINATE COMPARISON OF 1-DAY (Z1) SOLUTIONS ------------------------------------------------------------------------------- TOTAL NUMBER OF STATIONS: 26 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 3 PP P 14 66 7 BRUG 13101M005 6 PPPPPP 12 7 35 CRAR 66001M004 7 PPPPPPP 14 38 15 DAVR 66010M001 4 PPPP 39 12 7 DLFT 13502M006 7 PPPPPPP 1 1 8 GATR 7 PPPPPPP 6 7 7 GOPE 11502M002 7 PPPPPPP 1 3 3 GRAB 11001M004 4 PPPP 1 1 2 IRKZ 12313M003 6 PPPPPP 2 6 10 KHAB 12361M001 7 PPPPPPP 4 4 14 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LHAZ 21613M002 4 P P PP 2 4 15 METZ 10503M005 5 PPPPP - - - CONSTRAINED MTBG 11030M001 7 PPPPPPP 2 2 10 MTKA 21741S002 7 PPPPPPP 7 5 10 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REUN 97401M003 5 P P PPP 13 13 27 REYZ 10202M003 7 PPPPPPP 3 2 4 SUNM 50143M001 5 PPPPP - - - CONSTRAINED THU2 43001M002 7 PPPPPPP 6 4 26 VSLD 13502M008 5 PPP PP 13 25 30 WTZZ 14201M014 7 PPPPPPP 1 2 3 YARR 50107M006 2 PP - - - CONSTRAINED ZIMJ 14001M006 6 PPPPPP 2 2 4 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
