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) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1004N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10047.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 94 125 454022 13109 1.2 95 120 448828 12715 1.2 96 115 413492 11984 1.2 97 113 399599 11819 1.2 98 110 383103 11406 1.2 99 106 384678 11335 1.2 100 107 386843 11353 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 103 104 106 107 108 109 110 111 113 116 117 120 122 ------------------------------------------------------------------------------- 94 4 -- 7 3 4 5 3 5 8 6 6 5 6 6 95 3 -- 3 4 4 4 2 12 7 5 5 4 4 6 96 5 -- 5 7 3 5 4 7 8 5 5 3 5 5 97 3 -- 3 5 4 5 4 6 6 7 4 3 4 4 98 5 38 5 6 4 7 4 7 5 5 5 4 9 7 99 3 35 4 5 5 5 3 7 4 7 4 6 4 7 100 4 23 4 5 4 6 3 5 5 6 5 7 9 7 ------------------------------------------------------------------------------- ALL 4 33 5 5 4 5 3 7 6 6 5 5 6 6 ------------------------------------------------------------------------------- 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: 26 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 6 PPPPPP 24 49 79 BIPD 10094M001 6 PPP PPP 3 5 34 BORG 12205M004 7 PPPPPPP 3 3 15 BRUG 13101M005 6 PPPPPP 3 6 12 DLFT 13502M006 6 PPPPPP 2 2 3 DLRA 14208M002 7 PPPPPPP 3 5 17 GODZ 6 PP PPPP - - - FIXED HERP 13212M009 5 PPPPP 9 12 50 IRKZ 7 PPPPPPP 5 4 5 KR0G 10422M001 7 PPPPPPP - - - FIXED LDS1 13215M001 7 PPPPPPP 3 5 13 LINR 50124M001 6 PPP PPP 14 137 43 *) MDVZ 7 PPPPPPP 2 3 4 METZ 10503M005 7 PPPPPPP - - - FIXED MTKA 21741S002 7 PPPPPPP 6 4 5 NPLC 13234M001 7 PPPPPPP 28 40 104 OS0G 10402M004 7 PPPPPPP - - - FIXED REUN 97401M003 3 PPP 13 23 15 *) SL1X 40446S001 6 P PPPPP 3 13 14 STRR 50119M002 7 PPPPPPP 16 114 31 *) THU2 43001M002 6 PP PPPP 2 3 3 TSKA 21730M003 6 PPPPP P 6 5 5 VSLD 13502M008 7 PPPPPPP 6 6 23 WTZZ 14201M014 7 PPPPPPP 2 2 3 YARR 50107M006 4 PPPP - - - FIXED ZIMZ 14001M005 7 PPPPPPP - - - FIXED ------------------------------------------------------------------------------- *) Very isolated sites -------------------------------------------------------------------------------
