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: ------------------------------------------------------------------------------- COX0994N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09947.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 24 110 411793 10365 1.4 25 108 412816 10253 1.4 26 109 422296 10392 1.4 27 113 443645 11039 1.4 28 118 472027 11723 1.4 29 120 490266 12256 1.4 30 122 497343 12700 1.4 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103 104 106 107 108 109 110 111 113 116 117 120 122 ------------------------------------------------------------------------------- 24 5 9 13 -- -- 12 14 7 6 19 8 7 6 25 5 7 17 -- -- 4 17 7 5 23 7 5 4 26 4 6 10 -- -- 6 17 12 6 6 8 5 9 27 4 4 12 -- -- 5 18 7 6 12 6 5 9 28 7 6 9 -- -- 9 12 8 8 5 6 7 12 29 3 3 10 18 7 7 24 7 5 9 9 6 11 30 6 6 8 18 8 5 34 6 5 8 7 7 20 ------------------------------------------------------------------------------- ALL 5 6 12 18 7 7 21 8 6 13 7 6 11 ------------------------------------------------------------------------------- Remarks: - These RMS values may be too optimistic, because we fit the middle days of 5-day arcs with a 7-day arc. - Starting from DOY 029 the orbits for the newly launched GLONASS satellites with slot numbers 7 and 8 were determined. ------------------------------------------------------------------------------- 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 296 117 336 BIPD 10094M001 7 PPPPPPP 8 9 22 BORG 12205M004 7 PPPPPPP 6 8 19 BRUG 13101M005 7 PPPPPPP 7 10 18 CRAR 66001M004 7 PPPPPPP 13 16 16 CSIR 30310M001 4 P PPP 35 77 137 DLRA 14208M002 2 PP 6 2 21 HERP 13212M009 7 PPPPPPP 25 32 56 IRKZ 7 PPPPPPP 9 11 9 KHAB 7 PPPPPPP 12 6 7 KR0G 10422M001 3 PPP 4 3 13 LDS1 13215M001 7 PPPPPPP 6 15 26 LINR 6 PPPP PP 5 11 26 LRBA 10093M001 7 PPPPPPP 4 4 9 MDVZ 7 PPPPPPP 5 7 9 METZ 10503M005 7 PPPPPPP 4 2 13 NPLC 13234M001 7 PPPPPPP 69 43 72 OS0G 10402M004 6 P PPPPP 5 3 10 REUN 97401M003 7 PPPPPPP 8 17 20 STRR 50119M002 7 PPPPPPP 4 9 8 SUNM 50143M001 7 PPPPPPP 5 10 10 THU2 43001M002 6 PPPPPP 7 9 14 TSKA 21730M003 7 PPPPPPP 11 5 17 VSLD 13502M008 6 P PPPPP 4 8 23 YARR 50107M006 7 PPPPPPP - - - FIXED ZIMZ 14001M005 7 PPPPPPP - - - FIXED -------------------------------------------------------------------------------
