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) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1016N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10167.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 178 83 230388 8445 1.4 179 79 225664 8236 1.4 180 82 226415 8381 1.4 181 85 235202 8586 1.4 182 88 243168 9304 1.4 183 87 231205 9244 1.5 184 90 218293 9290 1.5 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 103 104 106 107 108 109 110 111 113 115 116 117E120E122E ------------------------------------------------------------------------------- 178 4 4 6 16 6 8 7 21 10 10 21 13 13 6 6 179 6 4 5 19 3 7 14 15 9 7 17 11 11 8 11 180 5 6 5 11 4 11 10 8 6 7 21 18 9 8 8 181 4 6 7 18 9 12 10 10 14 13 16 10 9 9 11 182 9 8 7 12 8 14 12 20 18 12 19 21 8 8 6 183 7 7 7 16 6 16 22 16 7 24 23 23 10 10 8 184 12 9 9 16 14 26 10 17 9 31 19 12 20 9 10 ------------------------------------------------------------------------------- ALL 7 7 7 15 8 15 13 16 11 17 19 16 12 8 9 ------------------------------------------------------------------------------- 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 ------------------------------------------------------------------------------- 3SNA 49918S001 4 PP PP 78 105 40 BORG 12205M004 7 PPPPPPP 2 9 16 BRUG 13101M005 7 PPPPPPP 3 7 14 DLFT 13502M006 7 PPPPPPP 2 5 7 GODZ 5 PPP PP - - - FIXED HERP 13212M009 7 PPPPPPP 11 20 44 KHAB 6 P PPPPP 16 18 11 KR0G 10422M001 7 PPPPPPP - - - FIXED LDS1 13215M001 3 PPP 2 10 8 LINR 50124M001 5 PP PPP 9 28 26 MDVZ 7 PPPPPPP 6 4 11 MTKA 21741S002 7 PPPPPPP 16 20 18 NPLC 13234M001 7 PPPPPPP 8 15 54 OS0G 10402M004 7 PPPPPPP - - - FIXED REYZ 10202M003 7 PPPPPPP 3 5 15 SUNM 50143M001 7 PPPPPPP - - - FIXED THU2 43001M002 5 PPPPP 4 5 4 VSLD 13502M008 6 PPP PPP 4 11 13 ZIMJ 14001M006 7 PPPPPPP 2 6 5 ZIMZ 14001M005 7 PPPPPPP - - - FIXED -------------------------------------------------------------------------------
