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 ITRF97 coordinates: - GODZ 40451M123 (Greenbelt, USA) - KR0G 10422M001 (Kiruna, Sweden) - OS0G 10402M004 (Onsala, Sweden) - YARR 50107M006 (Yaragadee, Australia) - ZIMZ 14001M005 (Zimmerwald, Switzerland) ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX1052N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX10527.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 65 97 336894 9309 1.1 66 94 321716 9275 1.1 67 96 332183 9334 1.1 68 97 335600 9416 1.1 69 98 350179 9774 1.2 70 103 366896 9818 1.2 71 105 380144 9763 1.1 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 101 107 108 109E111E113E115E122 ------------------------------------------------------------------------------- 65 5 6 5 9 12 6 7 6 66 9 7 7 14 9 -- 12 9 67 7 4 5 5 13 6 5 6 68 7 7 7 7 5 3 4 6 69 6 4 3 4 9 2 7 6 70 5 3 8 6 7 5 10 6 71 4 5 5 5 11 5 11 8 ------------------------------------------------------------------------------- ALL 6 5 6 8 10 5 9 7 ------------------------------------------------------------------------------- Remark: These RMS values may be too optimistic, because we fit the middle days of 5-day arcs with a 7-day arc.
