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: ------------------------------------------------------------------------------- COX1036N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10367.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 318 120 451320 11140 1.2 319 120 456040 11311 1.2 320 120 448261 10883 1.2 321 120 444335 10846 1.2 322 115 421796 10409 1.1 323 111 414327 10090 1.1 324 111 417055 10098 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101E107E109 111 113 115 122 ------------------------------------------------------------------------------- 318 2 4 7 7 8 7 5 319 6 5 7 14 7 9 10 320 4 5 6 9 5 14 7 321 7 6 8 11 8 9 8 322 3 5 4 7 7 8 3 323 6 6 9 11 8 14 8 324 5 5 8 7 7 11 6 ------------------------------------------------------------------------------- ALL 5 5 7 10 7 11 7 ------------------------------------------------------------------------------- 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: 27 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 6 PPPPPP 15 28 55 BORG 12205M004 7 PPPPPPP 5 10 11 DAVR 66010M001 6 PPPPPP 6 10 8 DLFT 13502M006 7 PPPPPPP 2 2 3 GATR 5 PP P PP 1 2 7 GODZ 40451M123 6 PPPPPP - - - CONSTRAINED GOPE 11502M002 7 PPPPPPP 2 1 4 GRAB 11001M004 7 PPPPPPP 1 1 4 IRKZ 12313M003 7 PPPPPPP 4 3 5 KHAB 12361M001 6 PPPPPP 5 4 8 KR0G 10422M001 6 PPPPPP - - - CONSTRAINED LHAZ 21613M002 7 PPPPPPP 4 5 17 MDVZ 12309M004 5 PPP PP 2 4 6 METZ 10503M005 7 PPPPPPP - - - CONSTRAINED MTBG 11030M001 5 PP PPP 1 1 9 MTKA 21741S002 7 PPPPPPP 6 5 11 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REUN 97401M003 2 PP 6 13 18 REYZ 10202M003 5 PPPPP 2 5 8 SUNM 50143M001 3 PPP 7 6 4 THU2 43001M002 7 PPPPPPP 4 4 11 TSKA 21730M003 7 PPPPPPP 6 6 13 VSLD 13502M008 7 PPPPPPP 3 7 24 WTZZ 14201M014 7 PPPPPPP 1 1 4 YARR 50107M006 5 PPPPP - - - CONSTRAINED ZIMJ 14001M006 7 PPPPPPP 2 2 6 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
