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 3-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. - At present only the site ZIMZ (Zimmerwald, Switzerland) was constrained to its ITRF96 coordinates. ------------------------------------------------------------------------------- FILES AVAILABLE THROUGH ANONYMOUS FTP: ------------------------------------------------------------------------------- COR0980N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COR09807.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ THREE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 291 51 192240 4389 1.4 292 34 136825 3115 1.4 293 37 149754 3434 1.4 294 37 169252 3624 1.4 295 32 136298 3150 1.4 296 24 108660 2551 1.4 297 21 91450 2209 1.4 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103 104 106 109 110 111 112 113 115 116 117 118 120 122 ------------------------------------------------------------------------------- 291 35 24 21 79 127 90 96 89 90 71 22 19 32 28 292 28 22 27 69 122 69 97 71 85 68 50 16 19 25 293 30 38 28 78 97 65 78 62 75 83 21 14 19 24 294 24 29 42 53 91 48 59 48 60 67 31 23 18 20 295 31 29 60 62 72 75 64 57 64 96 44 35 15 27 296 25 24 31 62 110 91 53 70 70 97 44 29 26 36 297 39 27 43 95 124 112 84 88 89 104 31 31 26 23 ------------------------------------------------------------------------------- ALL 31 28 38 72 108 81 77 71 77 85 36 25 23 26 ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- WEEKLY COORDINATE COMPARISON OF 1-DAY (Z1) SOLUTIONS ------------------------------------------------------------------------------- TOTAL NUMBER OF STATIONS: 16 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- BORG 12205M004 2 PP 4 1 7 BRUG 13101M005 6 PPPPPP 8 6 5 DLRA 14208M002 3 P P P 10 7 16 GATR 2 PP 37 15 6 GODZ 6 PPPPPP 5 14 10 IRKZ 7 PPPPPPP 3 7 11 KHAB 7 PPPPPPP 6 11 5 KR0G 10422M001 6 PPPPP P 6 3 6 LDS1 13215M001 2 PP 3 3 9 METZ 10503M005 6 PPPPP P 6 5 9 MTKA 21741S002 1 P - - - OS0G 10402M004 1 P - - - REYZ 10202M003 5 PPPPP 5 3 3 SL1X 40446S001 2 PP 1 1 4 VSLD 13502M008 1 P - - - ZIMZ 14001M005 7 PPPPPPP 2 1 1 -------------------------------------------------------------------------------
