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: ------------------------------------------------------------------------------- COX1029N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10297.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 269 90 384670 9477 1.3 270 89 389972 9311 1.3 271 89 381617 9290 1.3 272 93 402235 9592 1.3 273 94 401345 9581 1.3 274 93 398710 9489 1.3 275 95 402853 9687 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 106 107 108 109 111 113 115 116 122 ------------------------------------------------------------------------------- 269 4 5 3 4 31 6 4 12 11 5 270 5 6 5 5 26 3 5 8 13 5 271 4 4 4 3 24 8 5 8 15 5 272 6 6 4 6 19 7 4 6 9 4 273 7 6 5 6 21 9 4 7 10 6 274 4 5 5 4 25 10 5 8 9 6 275 4 3 5 5 32 6 8 9 11 5 ------------------------------------------------------------------------------- ALL 5 5 4 5 26 7 5 8 11 5 ------------------------------------------------------------------------------- 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: 22 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BRUG 13101M005 1 P - - - DLFT 13502M006 7 PPPPPPP 2 3 6 GATR 7 PPPPPPP 3 7 9 GODZ 40451M123 6 PPPP PP - - - CONSTRAINED GRAB 11001M004 7 PPPPPPP 3 6 6 IRKZ 12313M003 6 PPP PPP 6 9 12 KHAB 12361M001 7 PPPPPPP 7 9 12 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LINR 50124M001 5 PPPPP 27 28 44 MDVZ 12309M004 7 PPPPPPP 2 2 8 METZ 10503M005 7 PPPPPPP - - - CONSTRAINED MTBG 11030M001 7 PPPPPPP 3 6 7 MTKA 21741S002 7 PPPPPPP 9 7 11 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REYZ 10202M003 6 PPPPPP 2 4 10 SUNM 50143M001 5 PPP PP 11 12 10 THU2 43001M002 6 PPPPPP 4 2 11 VSLD 13502M008 7 PPPPPPP 4 7 12 WTZZ 14201M014 7 PPPPPPP 2 5 8 YARR 50107M006 6 PPPPPP - - - CONSTRAINED ZIMJ 14001M006 7 PPPPPPP 2 3 8 ZIMZ 14001M005 2 PP - - - CONSTRAINED -------------------------------------------------------------------------------
