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: ------------------------------------------------------------------------------- COX1015N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10157.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 171 96 257069 9289 1.3 172 96 252045 9234 1.4 173 95 247623 9172 1.3 174 93 254534 9337 1.3 175 89 246163 9178 1.3 176 86 234051 8750 1.3 177 84 229813 8370 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 103 104 106 107 108 109 110 111 113 115 116 117E120E122E ------------------------------------------------------------------------------- 171 9 5 8 17 6 11 26 17 13 14 -- 18 11 6 10 172 8 5 6 8 8 11 17 17 7 8 -- 24 6 4 11 173 7 6 7 17 7 19 8 16 9 9 -- 18 8 5 8 174 8 4 6 7 6 13 15 11 6 12 -- 22 5 7 10 175 8 3 7 8 4 12 12 13 6 17 -- 20 6 8 9 176 8 8 5 7 3 5 14 14 7 18 16 18 7 10 13 177 8 6 4 10 7 10 15 27 8 7 16 24 9 11 5 ------------------------------------------------------------------------------- ALL 8 6 6 12 6 12 16 17 8 13 16 21 8 8 10 ------------------------------------------------------------------------------- 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: 22 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 6 PPP PPP 69 67 86 BIPD 10094M001 4 PPPP 5 10 26 BORG 12205M004 7 PPPPPPP 2 6 24 BRUG 13101M005 7 PPPPPPP 3 2 13 DLFT 13502M006 7 PPPPPPP 1 1 5 GODZ 7 PPPPPPP - - - FIXED HERP 13212M009 7 PPPPPPP 13 27 54 KHAB 7 PPPPPPP 3 12 10 KR0G 10422M001 7 PPPPPPP - - - FIXED LDS1 13215M001 5 PPPPP 2 6 18 LINR 50124M001 6 PPPPPP 22 39 42 MDVZ 2 PP 0 1 4 MTKA 21741S002 7 PPPPPPP 5 18 9 NPLC 13234M001 7 PPPPPPP 12 21 54 OS0G 10402M004 7 PPPPPPP - - - FIXED REYZ 10202M003 7 PPPPPPP 3 4 10 SUNM 50143M001 7 PPPPPPP - - - FIXED THU2 43001M002 6 PPPPPP 4 3 7 VSLD 13502M008 7 PPPPPPP 3 3 15 WTZZ 14201M014 2 PP 0 2 3 ZIMJ 14001M006 7 PPPPPPP 2 2 5 ZIMZ 14001M005 7 PPPPPPP - - - FIXED -------------------------------------------------------------------------------
