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) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1044N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10447.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 9 79 325980 8409 1.1 10 99 416595 10631 1.1 11 99 424749 10714 1.1 12 100 438475 10952 1.1 13 96 431546 10705 1.1 14 90 404906 10149 1.1 15 88 398141 9980 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109 111 113 115 116 122 ------------------------------------------------------------------------------- 9 4 5 5 6 7 4 6 -- 6 10 2 3 3 8 2 4 3 -- 4 11 3 2 5 6 2 3 2 -- 4 12 6 5 6 7 5 7 6 -- 6 13 5 3 7 4 4 3 3 -- 3 14 5 5 8 5 4 6 4 10 4 15 2 3 5 6 5 5 5 10 4 ------------------------------------------------------------------------------- ALL 4 4 6 6 5 5 4 10 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: 23 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BRUG 13101M005 2 PP 1 12 21 CRAR 66001M004 6 PPPP PP 6 17 12 DAVR 66010M001 7 PPPPPPP 13 7 8 DLFT 13502M006 7 PPPPPPP 3 1 3 GATR 7 PPPPPPP 8 10 9 GOPE 11502M002 7 PPPPPPP 2 1 3 GRAB 11001M004 7 PPPPPPP 2 1 4 IRKZ 12313M003 7 PPPPPPP 2 9 7 KHAB 12361M001 7 PPPPPPP 5 10 5 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LHAZ 21613M002 6 PP PPPP 5 11 10 METZ 10503M005 6 PPPPPP - - - CONSTRAINED MTBG 11030M001 7 PPPPPPP 2 1 3 MTKA 21741S002 7 PPPPPPP 7 10 6 NPLC 13234M001 1 P - - - OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REUN 97401M003 7 PPPPPPP 5 11 23 REYZ 10202M003 6 PPPPPP 3 5 9 THU2 43001M002 7 PPPPPPP 6 6 13 WTZZ 14201M014 7 PPPPPPP 2 1 4 YARR 50107M006 6 PPPPPP - - - CONSTRAINED ZIMJ 14001M006 6 PPPPPP 3 1 3 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
