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) - METZ 10503M005 (Metsahovi, Finland) - OS0G 10402M004 (Onsala, Sweden) - SUNM 50143M001 (Brisbane, Australia) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1027N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10277.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 255 93 372397 9556 1.3 256 94 382571 9812 1.3 257 94 382751 9685 1.3 258 95 391527 9891 1.3 259 94 392699 9681 1.3 260 90 381339 9303 1.3 261 91 389215 9548 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 106 107 108 109E111E113E115E116E122 ------------------------------------------------------------------------------- 255 6 26 5 5 10 10 9 13 8 7 256 9 22 6 8 9 12 13 10 8 8 257 5 15 4 5 5 5 8 8 4 4 258 6 8 4 2 7 7 7 4 5 5 259 4 11 7 6 6 8 8 5 4 4 260 5 17 7 4 5 7 5 9 7 5 261 6 -- 11 8 6 10 9 7 5 7 ------------------------------------------------------------------------------- ALL 6 17 7 6 7 9 9 9 6 6 ------------------------------------------------------------------------------- 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: 24 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 3 PPP 0 33 23 BRUG 13101M005 7 PPPPPPP 7 8 14 DLFT 13502M006 6 PPPP PP 2 4 6 GATR 2 PP 1 2 5 GODZ 7 PPPPPPP - - - FIXED GRAB 11011M004 5 PPPPP 2 4 4 HERP 13212M009 1 P - - - IRKZ 7 PPPPPPP 5 5 10 KHAB 7 PPPPPPP 5 8 10 KR0G 10422M001 7 PPPPPPP - - - FIXED LINR 50124M001 4 PPPP 6 21 39 MDVZ 7 PPPPPPP 2 3 5 METZ 10503M005 7 PPPPPPP - - - FIXED MTBG 11030M001 7 PPPPPPP 3 3 6 MTKA 21741S002 6 PPPPPP 7 8 12 OS0G 10402M004 7 PPPPPPP - - - FIXED REYZ 10202M003 6 PPPPPP 3 5 8 SUNM 50143M001 6 PPPPPP - - - FIXED THU2 43001M002 6 PPP PPP 4 3 9 VSLD 13502M008 7 PPPPPPP 4 6 9 WTZZ 14201M014 7 PPPPPPP 2 2 6 YARR 50107M006 4 PPPP - - - FIXED ZIMJ 14001M006 6 P PPPPP 2 2 9 ZIMZ 14001M005 4 PPPP - - - FIXED -------------------------------------------------------------------------------
