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) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1042N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10427.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 360 102 334722 9408 1.2 361 100 324266 9166 1.2 362 99 317028 8805 1.1 363 96 313514 8715 1.1 364 90 303148 8372 1.1 365 89 318900 8706 1.1 1 89 326405 9070 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109 111 113 115 116 122E ------------------------------------------------------------------------------- 360 4 3 4 8 6 4 3 14 6 361 3 5 5 13 5 10 4 6 5 362 3 3 3 11 9 8 7 5 5 363 4 5 4 7 5 4 2 4 6 364 5 5 3 11 7 9 6 8 3 365 4 6 4 11 8 5 6 7 6 1 5 4 6 10 5 4 5 7 5 ------------------------------------------------------------------------------- ALL 4 5 4 10 7 7 5 8 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: 25 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 6 PPP PPP 13 40 36 BORG 12205M004 6 PPPPPP 9 12 13 BRUG 13101M005 7 PPPPPPP 10 9 23 CRAR 66001M004 7 PPPPPPP 55 60 27 DLFT 13502M006 7 PPPPPPP 2 3 2 GODZ 40451M123 6 PPPPPP - - - CONSTRAINED GOPE 11502M002 7 PPPPPPP 3 2 6 GRAB 11001M004 4 PPPP 2 3 9 HERP 13212M009 2 PP 3 1 45 IRKZ 12313M003 3 PP P 10 3 1 KHAB 12361M001 1 P - - - KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LHAZ 21613M002 7 PPPPPPP 10 5 31 METZ 10503M005 7 PPPPPPP - - - CONSTRAINED MTBG 11030M001 7 PPPPPPP 3 2 6 MTKA 21741S002 2 PP 6 1 5 NPLC 13234M001 6 PPPPPP 13 23 47 OS0G 10402M004 5 PPPPP - - - CONSTRAINED REUN 97401M003 7 PPPPPPP 25 48 46 REYZ 10202M003 7 PPPPPPP 3 2 4 THU2 43001M002 7 PPPPPPP 5 3 6 TSKA 21730M003 2 PP 5 0 5 VSLD 13502M008 6 PPPPPP 5 10 15 WTZZ 14201M014 7 PPPPPPP 3 2 7 ZIMZ 14001M005 7 PPPPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
