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: ------------------------------------------------------------------------------- COX1040N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10407.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 346 123 452342 11451 1.2 347 120 448614 11051 1.2 348 122 456661 11295 1.2 349 125 466869 11451 1.2 350 122 453583 11038 1.2 351 121 448080 10807 1.2 352 123 449401 11015 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109 113 115 116 122E ------------------------------------------------------------------------------- 346 6 4 4 8 5 12 4 6 347 4 4 3 5 5 7 5 6 348 3 4 4 3 8 4 7 3 349 5 4 4 4 6 11 5 4 350 3 5 8 6 4 5 5 6 351 7 5 7 5 6 10 5 6 352 7 5 5 -- 18 10 7 6 ------------------------------------------------------------------------------- ALL 5 5 5 5 9 9 5 5 ------------------------------------------------------------------------------- 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: 28 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 7 PPPPPPP 16 20 62 BORG 12205M004 6 PPP PPP 8 11 13 BRUG 13101M005 7 PPPPPPP 6 3 11 DAVR 66010M001 5 PPP PP 42 31 10 DLFT 13502M006 7 PPPPPPP 2 2 5 GATR 7 PPPPPPP 6 10 12 GODZ 40451M123 6 PP PPPP - - - CONSTRAINED GOPE 11502M002 7 PPPPPPP 2 3 4 GRAB 11001M004 7 PPPPPPP 4 4 3 HERP 13212M009 3 PPP 29 56 67 IRKZ 12313M003 7 PPPPPPP 5 7 8 KHAB 12361M001 7 PPPPPPP 6 7 4 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LHAZ 21613M002 7 PPPPPPP 5 6 9 METZ 10503M005 5 PPPPP - - - CONSTRAINED MTBG 11030M001 6 PPPPPP 3 3 3 MTKA 21741S002 7 PPPPPPP 6 6 3 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REUN 97401M003 7 PPPPPPP 21 33 42 REYZ 10202M003 5 PPPPP 3 2 5 SUNM 50143M001 7 PPPPPPP 22 32 27 THU2 43001M002 5 PP PPP 5 5 10 TSKA 21730M003 7 PPPPPPP 6 6 3 VSLD 13502M008 7 PPPPPPP 4 6 15 WTZZ 14201M014 7 PPPPPPP 2 3 5 YARR 50107M006 5 PPPPP - - - CONSTRAINED ZIMJ 14001M006 6 PPPPPP 5 4 3 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
