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) - OS0G 10402M004 (Onsala, Sweden) - SUNM 50143M001 (Brisbane, Australia) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1061N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10617.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 128 98 378332 9713 1.1 129 97 377420 9526 1.1 130 95 363634 9389 1.2 131 96 363604 9451 1.2 132 92 346690 8935 1.2 133 88 328559 8461 1.2 134 89 323507 8295 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101E107E108E111 113 115 116 122 ------------------------------------------------------------------------------- 128 5 4 4 53 5 7 6 3 129 4 3 2 47 4 3 3 2 130 5 5 3 46 3 5 6 3 131 6 5 5 21 7 4 6 3 132 4 7 5 38 7 5 5 5 133 5 8 5 51 8 8 6 3 134 5 8 3 64 8 8 12 4 ------------------------------------------------------------------------------- ALL 5 6 4 47 6 6 7 3 ------------------------------------------------------------------------------- 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: 21 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 7 PPPPPPP 13 29 61 BORG 12205M004 5 PPP PP 5 11 6 CRAR 66001M004 7 PPPPPPP 2 7 9 DAVR 66010M001 6 PPPPPP 7 4 7 DLFT 13502M006 6 PPPP PP 2 3 6 GOPE 11502M002 7 PPPPPPP 2 3 3 GRAB 11001M004 7 PPPPPPP 2 3 3 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED MTBG 11030M001 7 PPPPPPP 4 3 5 MTKA 21741S002 7 PPPPPPP 5 20 9 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REUN 97401M003 7 PPPPPPP 9 17 31 REYZ 10202M003 7 PPPPPPP 2 5 11 SUNM 50143M001 7 PPPPPPP - - - CONSTRAINED THU2 43001M002 4 PPPP 1 2 4 TSKA 21730M003 6 PPPPPP 5 21 5 VSLD 13502M008 7 PPPPPPP 8 9 22 WTZZ 14201M014 7 PPPPPPP 4 3 4 YARR 50107M006 6 PPPPPP - - - CONSTRAINED ZIMJ 14001M006 6 PPPPPP 2 2 4 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
