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: - GODZ 40451M123 (Greenbelt, USA) - KR0G 10422M001 (Kiruna, Sweden) - METZ 10503M005 (Metsahovi, Finland) - OS0G 10402M004 (Onsala, Sweden) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1034N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10347.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 304 87 392211 9238 1.2 305 89 389505 9119 1.2 306 90 384385 9230 1.2 307 91 384909 9325 1.2 308 92 385132 9428 1.2 309 95 389181 9679 1.1 310 95 396547 10062 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101E107E108E109 111 113 115 116 122 ------------------------------------------------------------------------------- 304 5 8 8 6 8 5 5 2 3 305 5 11 8 2 4 6 2 7 4 306 5 7 5 9 6 7 4 4 2 307 7 7 4 5 5 5 6 9 6 308 7 4 4 4 5 8 6 6 1 309 -- 7 5 9 9 5 9 5 4 310 -- 7 7 9 8 3 7 4 5 ------------------------------------------------------------------------------- ALL 6 8 6 7 7 6 6 6 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: 21 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BORG 12205M004 4 PPPP 2 15 25 DLFT 13502M006 7 PPPPPPP 2 2 6 GATR 6 PP PPPP 3 3 5 GODZ 40451M123 7 PPPPPPP - - - CONSTRAINED GRAB 11001M004 7 PPPPPPP 1 2 4 IRKZ 12313M003 7 PPPPPPP 4 9 9 KHAB 12361M001 7 PPPPPPP 6 9 9 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED METZ 10503M005 7 PPPPPPP 2 1 2 MTBG 11030M001 6 PPPPPP - - - CONSTRAINED MTKA 21741S002 5 PPP PP 7 13 10 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REYZ 10202M003 7 PPPPPPP 2 2 6 SUNM 50143M001 7 PPPPPPP 5 11 17 THU2 43001M002 5 P PPPP 3 3 4 TSKA 21730M003 7 PPPPPPP 6 10 13 VSLD 13502M008 7 PPPPPPP 5 6 14 WTZZ 14201M014 7 PPPPPPP 2 2 5 YARR 50107M006 7 PPPPPPP - - - CONSTRAINED ZIMJ 14001M006 5 P PPPP 2 4 6 ZIMZ 14001M005 6 PPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
