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. - Site ZIMZ (Zimmerwald, Switzerland) and site YARR (Yaragadee, Australia) were constrained to their ITRF96 coordinates. ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX0993N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09937.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 17 100 391198 9993 1.4 18 100 403736 10390 1.4 19 104 425874 10940 1.4 20 108 430380 11321 1.4 21 111 445691 11437 1.4 22 111 446064 11131 1.4 23 111 431426 10785 1.4 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103 104 106 109 110 111 113 116 117 120 122 ------------------------------------------------------------------------------- 17 4 7 7 28 18 8 10 32 322 6 5 18 4 5 6 20 13 14 3 28 148 5 5 19 3 3 6 29 10 4 5 7 112 2 6 20 7 10 11 12 9 12 6 13 86 7 6 21 4 5 6 15 9 4 7 12 50 6 5 22 5 8 9 32 8 9 5 17 83 5 6 23 5 5 9 36 11 7 6 14 75 6 4 ------------------------------------------------------------------------------- ALL 5 6 8 26 12 9 6 20 151 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. - The 5-day arcs of GLONASS satellite no. 117 were splitted up between DOY 17 and DOY 18 due to satellite modeling problems. ------------------------------------------------------------------------------- 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 7 PPPPPPP 73 69 100 BIPD 10094M001 7 PPPPPPP 5 16 16 BORG 12205M004 7 PPPPPPP 3 9 19 BRUG 13101M005 7 PPPPPPP 3 9 25 CRAR 66001M004 5 PPPPP 11 13 17 CSIR 30310M001 1 P - - - HERP 13212M009 6 PPPPPP 19 60 88 IRKZ 6 P PPPPP 5 7 6 KHAB 7 PPPPPPP 6 13 10 KR0G 10422M001 5 PP PPP 3 3 6 LDS1 13215M001 6 PPP PPP 1 5 21 LINR 4 P PPP 34 6 17 LRBA 10093M001 7 PPPPPPP 2 5 8 MDVZ 7 PPPPPPP 4 7 6 METZ 10503M005 7 PPPPPPP 3 4 7 NPLC 13234M001 7 PPPPPPP 42 32 89 OS0G 10402M004 5 PP PPP 3 4 4 REUN 97401M003 6 PPP PPP 24 21 20 REYZ 10202M003 6 PPPPPP 2 3 8 STRR 50119M002 5 PPPPP 17 10 13 SUNM 50143M001 4 PPP P 3 6 6 THU2 43001M002 7 PPPPPPP 2 2 10 TSKA 21730M003 7 PPPPPPP 9 14 9 VSLD 13502M008 7 PPPPPPP 2 9 16 YARR 50107M006 7 PPPPPPP - - - FIXED ZIMZ 14001M005 7 PPPPPPP - - - FIXED -------------------------------------------------------------------------------
