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) - 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: ------------------------------------------------------------------------------- COX1046N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10467.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 23 92 407645 10306 1.1 24 91 398234 10060 1.1 25 92 397773 9990 1.1 26 93 395220 9636 1.1 27 91 379823 9256 1.1 28 89 363707 8719 1.1 29 91 366600 8857 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109 111 113 115 116 122 ------------------------------------------------------------------------------- 23 3 3 3 6 5 7 7 6 4 24 3 4 4 3 6 2 5 17 4 25 3 3 3 3 5 3 6 6 4 26 4 4 3 5 5 5 5 7 4 27 3 3 5 4 6 3 4 7 3 28 2 2 2 3 4 3 4 7 3 29 5 2 3 5 4 5 4 9 4 ------------------------------------------------------------------------------- ALL 3 3 4 4 5 4 5 9 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: 24 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BORG 12205M004 4 PPPP 2 21 3 BRUG 13101M005 5 PPPP P 11 8 27 CRAR 66001M004 2 PP 5 11 2 DAVR 66010M001 4 PPPP 7 28 17 DLFT 13502M006 7 PPPPPPP 3 4 3 GATR 7 PPPPPPP 13 8 20 GOPE 11502M002 7 PPPPPPP 2 4 5 GRAB 11001M004 7 PPPPPPP 4 3 4 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LHAZ 21613M002 3 PP P 7 12 17 METZ 10503M005 6 PPP PPP - - - CONSTRAINED MTBG 11030M001 7 PPPPPPP 4 4 4 MTKA 21741S002 7 PPPPPPP 7 12 14 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REYZ 10202M003 7 PPPPPPP 3 3 6 SUNM 50143M001 3 PPP - - - CONSTRAINED THU2 43001M002 7 PPPPPPP 5 6 5 TSKA 21730M003 6 PPP PPP 9 12 15 VSLD 13502M008 3 PPP 5 25 14 WTZZ 14201M014 7 PPPPPPP 3 3 4 YARR 50107M006 5 PP PPP - - - CONSTRAINED ZIMJ 14001M006 7 PPPPPPP 4 3 6 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
