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 ITRF96 coordinates: - GODZ 40451M123 (Greenbelt, USA) - KR0G 10422M001 (Kiruna, Sweden) - OS0G 10402M004 (Onsala, Sweden) - SUNM 50143M001 (Brisbane, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1022N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10227.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 220 98 351852 10519 1.4 221 100 370256 10982 1.5 222 101 381668 11200 1.5 223 102 398927 11426 1.5 224 100 406049 11374 1.4 225 96 403012 10974 1.4 226 91 385027 10598 1.4 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 104 106 107 108 109 110 111 113 115 116 120 122 ------------------------------------------------------------------------------- 220 6 5 65 78 5 5 6 7 6 14 8 6 32 221 5 4 24 84 5 5 6 7 4 24 6 2 40 222 3 8 23 65 6 5 7 6 4 20 10 4 33 223 5 4 5 85 4 8 7 5 5 20 10 2 34 224 7 5 12 62 10 5 15 9 4 19 11 4 26 225 6 3 15 74 9 5 12 12 3 20 9 2 32 226 5 4 17 52 9 4 9 9 4 17 6 4 19 ------------------------------------------------------------------------------- ALL 5 5 29 72 7 5 9 8 4 19 9 4 31 ------------------------------------------------------------------------------- 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: 24 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 6 PPPPPP 38 44 171 BIPD 10094M001 7 PPPPPPP 21 58 94 BRUG 13101M005 7 PPPPPPP 3 6 10 DLFT 13502M006 7 PPPPPPP 1 2 4 GATR 7 PPPPPPP 11 7 22 GODZ 1 P - - - FIXED HERP 13212M009 7 PPPPPPP 8 21 43 IRKZ 7 PPPPPPP 4 11 59 KHAB 6 PPPPPP 8 14 14 KR0G 10422M001 7 PPPPPPP - - - FIXED LDS1 13215M001 5 PPPPP 2 3 28 LINR 50124M001 3 PPP 5 13 37 MDVZ 6 PPPP PP 4 4 7 MTBG 11030M001 5 PPPPP 1 4 3 MTKA 21741S002 7 PPPPPPP 11 20 14 OS0G 10402M004 7 PPPPPPP - - - FIXED REUN 97401M003 2 PP 17 61 12 REYZ 10202M003 6 PPPPPP 4 2 6 SUNM 50143M001 7 PPPPPPP - - - FIXED THU2 43001M002 7 PPPPPPP 4 4 10 VSLD 13502M008 7 PPPPPPP 4 5 13 WTZZ 14201M014 7 PPPPPPP 1 3 4 ZIMJ 14001M006 7 PPPPPPP 2 2 4 ZIMZ 14001M005 7 PPPPPPP - - - FIXED -------------------------------------------------------------------------------
