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: - GODZ 40451M123 (Greenbelt, USA) - KR0G 10422M001 (Kiruna, Sweden) - METZ 10503M005 (Metsahovi, Finland) - OS0G 10402M004 (Onsala, Sweden) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1031N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10317.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 283 92 409908 10266 1.3 284 90 400747 10141 1.3 285 92 415797 10424 1.2 286 91 415648 10138 1.2 287 92 420656 10266 1.2 288 89 411448 9994 1.2 289 91 418705 10143 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 106 107 108 109 111 113 115 116 122 ------------------------------------------------------------------------------- 283 9 10 6 8 4 10 5 7 8 9 284 6 4 4 5 4 3 4 11 10 6 285 7 8 7 9 9 10 9 11 14 8 286 8 7 7 6 9 7 8 6 10 7 287 7 5 6 8 5 7 7 5 12 6 288 10 9 9 8 12 14 11 10 13 7 289 7 4 6 7 12 12 9 8 15 5 ------------------------------------------------------------------------------- ALL 8 7 7 7 9 10 8 9 12 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: 21 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- DLFT 13502M006 6 P PPPPP 3 3 4 GATR 7 PPPPPPP 5 8 17 GODZ 40451M123 6 PPPPPP - - - CONSTRAINED GRAB 11001M004 6 P PPPPP 2 3 2 IRKZ 12313M003 7 PPPPPPP 4 11 8 KHAB 12361M001 7 PPPPPPP 7 13 11 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LINR 50124M001 7 PPPPPPP 12 41 41 MDVZ 12309M004 7 PPPPPPP 2 1 4 METZ 10503M005 7 PPPPPPP - - - CONSTRAINED MTBG 11030M001 6 PPP PPP 3 2 2 MTKA 21741S002 7 PPPPPPP 9 15 14 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REYZ 10202M003 7 PPPPPPP 2 3 6 SUNM 50143M001 2 PP 1 4 3 THU2 43001M002 7 PPPPPPP 5 4 7 VSLD 13502M008 6 P PPPPP 5 14 13 WTZZ 14201M014 6 PPP PPP 2 2 5 YARR 50107M006 7 PPPPPPP - - - CONSTRAINED ZIMJ 14001M006 7 PPPPPPP 1 3 5 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
