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 ITRF96 coordinates: - GODZ 40451M123 (Greenbelt, USA) - 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: ------------------------------------------------------------------------------- COX1013N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10137.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 157 97 265466 8714 1.4 158 99 268760 9100 1.4 159 100 269842 9119 1.4 160 101 273731 9472 1.3 161 97 262889 9024 1.3 162 94 243474 8682 1.3 163 93 229627 8283 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101E103E104E106E107E108E109 110 111 113 116 117E120E122E ------------------------------------------------------------------------------- 157 6 9 7 20 10 13 13 74 35 35 34 12 17 9 158 6 7 6 14 11 8 21 44 48 20 21 10 12 7 159 5 12 8 16 6 12 12 23 22 22 13 13 21 11 160 6 9 9 14 7 8 21 37 34 40 32 14 13 13 161 4 9 6 14 7 8 14 27 25 13 14 9 4 8 162 7 12 5 19 7 8 15 24 23 35 26 10 10 12 163 6 8 8 12 10 9 19 21 25 39 30 11 11 15 ------------------------------------------------------------------------------- ALL 6 10 7 16 8 10 17 40 31 31 25 11 13 11 ------------------------------------------------------------------------------- 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: 24 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 6 PPPPPP 48 376 444 BIPD 10094M001 3 PP P 0 16 56 BORG 12205M004 7 PPPPPPP 3 6 22 BRUG 13101M005 7 PPPPPPP 4 5 11 DLFT 13502M006 7 PPPPPPP 3 2 6 GODZ 7 PPPPPPP - - - FIXED HERP 13212M009 7 PPPPPPP 16 25 40 KR0G 10422M001 7 PPPPPPP - - - FIXED LDS1 13215M001 7 PPPPPPP 3 2 13 LINR 50124M001 6 PPP PPP 10 7 33 MDVZ 2 PP 1 2 6 MTKA 21741S002 6 PPPPPP 13 22 20 NPLC 13234M001 7 PPPPPPP 5 11 40 OS0G 10402M004 7 PPPPPPP - - - FIXED REUN 97401M003 7 PPPPPPP 19 57 23 REYZ 10202M003 2 P P 4 15 1 STRR 50119M002 5 PPPPP 5 7 9 SUNM 50143M001 7 PPPPPPP - - - FIXED THU2 43001M002 5 PPP PP 5 5 7 VSLD 13502M008 7 PPPPPPP 9 5 29 WTZZ 14201M014 7 PPPPPPP 3 3 4 YARR 50107M006 4 PPPP - - - FIXED ZIMJ 14001M006 7 PPPPPPP 3 2 3 ZIMZ 14001M005 6 PPPPPP - - - FIXED -------------------------------------------------------------------------------
