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: - 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: ------------------------------------------------------------------------------- COX0996N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09967.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 38 108 452983 11286 1.3 39 113 489970 11609 1.3 40 118 525552 12142 1.3 41 123 564682 12420 1.3 42 128 605590 12999 1.2 43 127 605637 12981 1.2 44 125 610084 13161 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103 104 106 107 108 109 110 111 113 116 117 118 120 122 ------------------------------------------------------------------------------- 38 5 5 8 5 5 6 10 8 8 9 8 7 4 4 39 6 8 15 7 5 5 5 7 7 5 13 7 7 5 40 5 5 9 9 5 4 8 7 3 7 6 5 4 4 41 5 5 10 7 6 6 9 7 7 7 9 4 6 4 42 6 6 10 9 8 6 7 7 6 7 7 6 5 7 43 3 5 7 6 4 6 8 3 3 4 8 4 4 4 44 6 5 7 9 9 6 12 12 7 4 8 5 6 7 ------------------------------------------------------------------------------- ALL 5 5 10 7 6 6 9 8 6 6 9 5 5 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: 28 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 7 PPPPPPP 30 74 48 BIPD 10094M001 6 PPPP PP 8 30 30 BORG 12205M004 7 PPPPPPP 4 4 16 BRUG 13101M005 7 PPPPPPP 6 11 17 DLRA 14208M002 7 PPPPPPP 3 9 19 HERP 13212M009 7 PPPPPPP 21 32 89 IRKZ 7 PPPPPPP 2 6 6 KHAB 7 PPPPPPP 2 9 5 KR0G 10422M001 7 PPPPPPP - - - CONSTRAINED LDS1 13215M001 6 PPPPPP 9 13 15 LINR 6 PPPPP P 5 53 37 LRBA 10093M001 7 PPPPPPP 7 10 3 MAGD 5 PPPPP 2 5 8 MDVZ 7 PPPPPPP 1 1 6 METZ 10503M005 5 P PPPP - - - CONSTRAINED NPLC 13234M001 6 PPPPPP 51 93 106 OS0G 10402M004 7 PPPPPPP - - - CONSTRAINED REUN 97401M003 3 P PP 16 36 24 STRR 50119M002 7 PPPPPPP 29 66 70 SUNM 50143M001 7 PPPPPPP 25 69 62 THU2 43001M002 5 PPPPP 5 6 7 TSKA 21730M003 7 PPPPPPP 4 13 6 VSLD 13502M008 7 PPPPPPP 3 6 9 WTZZ 14201M014 5 PPPPP 2 2 4 YAKT 5 PPPPP 2 6 6 YARR 50107M006 4 PPPP - - - CONSTRAINED ZIMJ 14001M006 5 PPPPP 3 2 4 ZIMZ 14001M005 5 PPPPP - - - CONSTRAINED -------------------------------------------------------------------------------
