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) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1028N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10287.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 262 93 408287 9934 1.3 263 92 407447 9934 1.3 264 92 401541 9794 1.3 265 94 399467 9981 1.3 266 92 393267 9729 1.3 267 88 368823 9292 1.3 268 89 370233 9207 1.4 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 106 107 108 109E111E113E115E116E122 ------------------------------------------------------------------------------- 262 9 14 11 10 14 9 9 14 18 9 263 14 18 16 13 14 17 13 14 12 13 264 10 11 10 7 9 7 7 8 11 7 265 7 11 10 7 6 9 9 8 10 7 266 13 13 14 12 10 13 10 12 16 13 267 4 7 6 6 8 7 8 8 15 5 268 8 10 7 10 12 14 11 15 18 9 ------------------------------------------------------------------------------- ALL 10 12 11 9 11 11 10 12 15 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: 21 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BRUG 13101M005 7 PPPPPPP 2 5 16 DLFT 13502M006 6 PPP PPP 3 4 8 GATR 6 PPPP PP 4 7 9 GODZ 6 PPPP PP - - - FIXED GRAB 11011M004 7 PPPPPPP 2 3 5 IRKZ 6 PPPP PP 8 7 9 KHAB 7 PPPPPPP 13 9 6 KR0G 10422M001 7 PPPPPPP - - - FIXED LINR 50124M001 5 PPPPP 7 39 31 MDVZ 7 PPPPPPP 3 2 4 METZ 10503M005 7 PPPPPPP - - - FIXED MTBG 11030M001 7 PPPPPPP 3 2 9 MTKA 21741S002 6 PPPPPP 11 9 10 OS0G 10402M004 7 PPPPPPP - - - FIXED REYZ 10202M003 7 PPPPPPP 2 1 7 SUNM 50143M001 6 PPPPPP - - - FIXED THU2 43001M002 7 PPPPPPP 6 2 3 VSLD 13502M008 6 PPP PPP 2 10 20 WTZZ 14201M014 7 PPPPPPP 1 1 6 YARR 50107M006 4 PPPP - - - FIXED ZIMJ 14001M006 7 PPPPPPP 2 3 6 -------------------------------------------------------------------------------
