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: - 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: ------------------------------------------------------------------------------- COX1023N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10237.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 227 89 382995 10621 1.4 228 85 367568 10182 1.4 229 86 360335 10320 1.4 230 85 355228 10035 1.4 231 84 353278 9731 1.4 232 79 323523 8979 1.3 233 77 308814 8652 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 104 106 107 108 109 110 111 113 115 116 120 122 ------------------------------------------------------------------------------- 227 4 8 23 5 3 12 13 6 11 12 11 6 4 228 5 6 21 8 6 14 12 6 7 20 14 10 4 229 3 7 22 8 8 7 11 8 7 7 7 5 5 230 3 4 20 7 6 12 6 5 7 8 8 7 4 231 4 3 23 7 5 10 16 5 5 7 8 4 5 232 4 3 26 8 6 9 12 7 6 5 4 9 2 233 5 5 28 6 4 8 13 5 10 8 6 6 4 ------------------------------------------------------------------------------- ALL 4 5 23 7 6 11 12 6 8 11 9 7 4 ------------------------------------------------------------------------------- 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: 20 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BRUG 13101M005 7 PPPPPPP 4 1 13 DLFT 13502M006 7 PPPPPPP 2 3 8 GATR 5 PPPPP 8 7 23 HERP 13212M009 7 PPPPPPP 19 30 30 IRKZ 6 PPPPPP 5 11 18 KHAB 7 PPPPPPP 9 15 15 KR0G 10422M001 5 PPPPP - - - FIXED LINR 50124M001 5 PP PPP 14 20 91 MDVZ 7 PPPPPPP 2 5 12 MTBG 11030M001 7 PPPPPPP 3 3 9 MTKA 21741S002 7 PPPPPPP 9 16 12 OS0G 10402M004 7 PPPPPPP - - - FIXED REYZ 10202M003 7 PPPPPPP 4 4 9 SUNM 50143M001 5 P PPPP - - - FIXED THU2 43001M002 6 PPP PPP 6 2 8 VSLD 13502M008 6 PPP PPP 5 4 16 WTZZ 14201M014 7 PPPPPPP 4 2 10 YARR 50107M006 7 PPPPPPP - - - FIXED ZIMJ 14001M006 7 PPPPPPP 4 4 14 ZIMZ 14001M005 4 P PPP - - - FIXED -------------------------------------------------------------------------------
