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) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1026N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10267.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 248 98 415034 10397 1.3 249 98 415993 10321 1.3 250 96 407666 10127 1.3 251 95 397303 9927 1.3 252 93 380866 9597 1.4 253 92 370231 9436 1.3 254 91 360219 9407 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 106 107 108 109E111E113E115E116E120 122 ------------------------------------------------------------------------------- 248 4 38 20 8 6 5 9 8 68 5 9 249 4 45 17 5 7 4 9 4 46 8 7 250 5 59 28 8 7 5 7 4 55 7 16 251 6 63 28 11 5 6 9 5 79 8 19 252 6 194 41 11 5 3 8 8 184 8 17 253 7 175 50 13 9 5 8 10 -- -- 30 254 8 195 47 15 9 9 13 10 135 -- 22 ------------------------------------------------------------------------------- ALL 6 129 35 11 7 6 9 7 107 8 19 ------------------------------------------------------------------------------- Remarks: - These RMS values may be too optimistic, because we fit the middle days of 5-day arcs with a 7-day arc. - The 5-day arcs of GLONASS satellite no. 106 were split up between DOY 251/252 and DOY 252/253 due to satellite modeling problems. ------------------------------------------------------------------------------- WEEKLY COORDINATE COMPARISON OF 1-DAY (Z1) SOLUTIONS ------------------------------------------------------------------------------- TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 5 PPPPP 4 10 52 BRUG 13101M005 7 PPPPPPP 2 5 14 DLFT 13502M006 7 PPPPPPP 1 2 5 GATR 4 PPPP 2 7 10 GODZ 6 PPPPP P - - - FIXED HERP 13212M009 2 PP 4 10 25 IRKZ 7 PPPPPPP 6 6 6 KHAB 7 PPPPPPP 9 6 5 KR0G 10422M001 7 PPPPPPP - - - FIXED LINR 50124M001 5 PP PPP 10 31 13 MDVZ 7 PPPPPPP 1 2 4 METZ 10503M005 7 PPPPPPP - - - FIXED MTBG 11030M001 7 PPPPPPP 2 1 5 MTKA 21741S002 7 PPPPPPP 10 6 3 OS0G 10402M004 7 PPPPPPP - - - FIXED REYZ 10202M003 6 PPPPPP 4 2 7 SUNM 50143M001 7 PPPPPPP - - - FIXED THU2 43001M002 7 PPPPPPP 4 6 7 VSLD 13502M008 7 PPPPPPP 5 8 14 WTZZ 14201M014 7 PPPPPPP 2 2 4 ZIMJ 14001M006 7 PPPPPPP 2 3 6 ZIMZ 14001M005 6 PPPPPP - - - FIXED -------------------------------------------------------------------------------
