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: - 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: ------------------------------------------------------------------------------- COX1057N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10577.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 100 97 336382 9301 1.1 101 99 341071 9095 1.1 102 101 347724 8900 1.1 103 102 350403 8653 1.1 104 105 357485 8941 1.1 105 108 367866 9417 1.1 106 107 366837 9359 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109 111 113 115 122 ------------------------------------------------------------------------------- 100 8 10 10 4 4 6 4 4 101 5 8 6 4 9 5 7 3 102 7 8 10 7 8 6 5 7 103 5 8 9 6 5 7 3 5 104 7 7 6 8 9 5 6 4 105 7 6 3 9 9 5 4 3 106 9 7 9 5 -- 5 4 4 ------------------------------------------------------------------------------- ALL 7 8 8 6 7 5 5 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: 23 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 7 PPPPPPP 6 27 77 BORG 12205M004 7 PPPPPPP 3 4 13 CRAR 66001M004 1 P - - - DAVR 66010M001 7 PPPPPPP 6 5 10 DLFT 13502M006 7 PPPPPPP 2 1 3 GATR 6 PPPPP P 8 6 12 GOPE 11502M002 7 PPPPPPP 1 1 4 GRAB 11001M004 7 PPPPPPP 2 3 3 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LHAZ 21613M002 4 PPPP 7 2 17 MTBG 11030M001 7 PPPPPPP 2 1 5 MTKA 21741S002 5 PPPPP 12 4 3 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REUN 97401M003 7 PPPPPPP 6 14 16 REYZ 10202M003 7 PPPPPPP 3 5 6 SUNM 50143M001 4 PP PP - - - CONSTRAINED THU2 43001M002 7 PPPPPPP 2 2 6 TSKA 21730M003 6 PPPPPP 13 4 8 VSLD 13502M008 6 P PPPPP 2 4 20 WTZZ 14201M014 6 PP PPPP 2 2 4 YARR 50107M006 7 PPPPPPP - - - CONSTRAINED ZIMJ 14001M006 7 PPPPPPP 2 2 3 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
