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. - Two different types of orbit fits were performed to check the consistency of the orbit results (see tables below): - One 7-day arc through all daily orbit solutions of the week. - Seven 3-day arcs. Note that the RMS values in the table are referred to the middle day of the corresponding 3-day arc. ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX0982N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09827.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ THREE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 305 42 216292 4774 1.4 306 41 213980 4722 1.3 307 42 211160 4808 1.3 308 44 221938 5012 1.3 309 46 228441 5018 1.3 310 45 228250 4955 1.3 311 41 205934 4666 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- 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 ------------------------------------------------------------------------------- 305 20 25 31 135 59 122 33 146 113 49 28 22 19 17 306 19 17 32 102 39 97 32 148 83 54 25 30 22 19 307 34 25 31 95 47 87 44 -- 84 53 23 16 20 20 308 27 22 31 49 32 44 61 -- 67 76 21 22 22 20 309 33 28 31 104 37 98 99 66 88 45 20 16 25 22 310 30 24 34 103 48 98 -- 77 99 65 21 22 19 19 311 32 25 49 135 52 137 -- 108 121 67 26 27 22 27 ------------------------------------------------------------------------------- ALL 28 24 34 107 46 101 59 114 95 59 24 23 21 21 ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM 3-DAY FITS THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103 104 106 109 110 111 112 113 115 116 117 118 120 122 ------------------------------------------------------------------------------- 305 6 7 18 11 30 9 24 10 14 29 10 13 5 7 306 10 9 10 14 27 8 7 9 10 27 8 14 5 4 307 10 10 8 16 17 8 16 -- 14 15 8 10 5 4 308 10 8 8 6 17 7 63 -- 12 20 9 8 5 4 309 8 7 9 8 11 9 41 4 8 20 5 6 7 6 310 8 7 15 8 12 10 -- 9 7 13 5 7 7 8 311 8 5 14 10 8 16 -- 8 7 19 9 7 5 8 ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- WEEKLY COORDINATE COMPARISON OF 1-DAY (Z1) SOLUTIONS ------------------------------------------------------------------------------- TOTAL NUMBER OF STATIONS: 17 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 7 MMMMMMM 5 14 19 BORG 12205M004 7 MMMMMMM 5 5 4 BRUG 13101M005 7 MMMMMMM 5 6 3 DLRA 14208M002 7 MMMMMMM 7 6 7 GODZ 7 MMMMMMM 4 1 3 IRKZ 7 MMMMMMM 4 5 19 KHAB 7 MMMMMMM 5 9 16 KR0G 10422M001 7 MMMMMMM 5 5 2 LDS1 13215M001 7 MMMMMMM 5 8 6 LRBA 10093M001 7 MMMMMMM 5 6 1 METZ 10503M005 7 MMMMMMM 5 4 4 MTKA 21741S002 4 MMMM 7 7 5 OS0G 10402M004 7 MMMMMMM 5 5 2 REYZ 10202M003 7 MMMMMMM 4 4 2 SL1X 40446S001 7 MMMMMMM 2 2 3 VSLD 13502M008 7 MMMMMMM 9 12 8 ZIMZ 14001M005 7 WWWWWWW 3 2 2 ------------------------------------------------------------------------------- # Coordinate Estimates: 116 5 6 8 -------------------------------------------------------------------------------
