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) - METZ 10503M005 (Metsahovi, Finland) - OS0G 10402M004 (Onsala, Sweden) - SUNM 50143M001 (Brisbane, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1025N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10257.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 241 84 338781 9581 1.3 242 87 353967 10036 1.3 243 91 370152 10363 1.3 244 94 385791 10332 1.3 245 97 401613 10671 1.3 246 97 401783 10440 1.4 247 98 409302 10512 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 104 106 107 108 109E110E111E113E115E116E120 122 ------------------------------------------------------------------------------- 241 5 8 32 6 9 6 9 8 7 12 23 6 4 242 4 4 29 4 5 6 11 5 7 9 19 6 4 243 8 11 21 5 8 8 6 8 9 12 13 8 6 244 6 7 33 5 7 9 6 9 8 5 10 4 6 245 8 13 28 7 10 9 9 7 9 6 14 6 5 246 9 14 25 9 10 9 18 13 6 7 23 6 7 247 6 -- 26 5 5 6 11 10 5 9 21 5 5 ------------------------------------------------------------------------------- ALL 7 10 28 6 8 8 11 9 7 9 18 6 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: 22 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BIPD 10094M001 7 PPPPPPP 17 65 99 BRUG 13101M005 4 PPPP 2 8 11 DLFT 13502M006 7 PPPPPPP 3 3 6 GATR 1 P - - - GODZ 7 PPPPPPP - - - FIXED HERP 13212M009 3 PPP 20 70 80 IRKZ 7 PPPPPPP 7 8 11 KHAB 7 PPPPPPP 12 5 14 KR0G 10422M001 7 PPPPPPP - - - FIXED LINR 50124M001 6 PPPPPP 10 17 57 MDVZ 7 PPPPPPP 3 3 4 METZ 10503M005 5 PPP PP - - - FIXED MTBG 11030M001 7 PPPPPPP 3 3 9 MTKA 21741S002 5 PPPPP 18 2 11 OS0G 10402M004 7 PPPPPPP - - - FIXED REYZ 10202M003 6 PPPPPP 3 3 7 SUNM 50143M001 6 PPPPPP - - - FIXED THU2 43001M002 7 PPPPPPP 5 4 6 VSLD 13502M008 7 PPPPPPP 4 3 15 WTZZ 14201M014 7 PPPPPPP 3 3 6 ZIMJ 14001M006 7 PPPPPPP 3 3 5 ZIMZ 14001M005 7 PPPPPPP - - - FIXED -------------------------------------------------------------------------------
