IGS orbits and Earth rotation parameters are fixed. Six initial conditions and nine radiation pressure parameters per satellite are determined for GLONASS satellites. The middle day of a 3-day-arc is used for the daily orbit results. The daily orbit files include GPS satellite clock values from IGS estimates and broadcasted values for GLONASS satellite clocks. The coordinates of the following stations are contrained to ITRF-97: GODZ IRKZ OS0G YARR ZIMZ WTZZ. GLONASS/GPS TIME OFFSET: Code observations of combined GLONASS/GPS receivers are used to determine the GLONASS/GPS time offset. This offset includes the modulo 1 sec system time scale difference of GLONASS and GPS and an additional offset between the receiver's 'GPS clock' and 'GLONASS clock'. The additional offset is receiver dependent. TRANSFORMATION PARAMETERS BETWEEN ITRF AND PZ90: The transformation parameters are derived from GLONASS precise orbits (given in ITRF) and GLONASS broadcast orbits (given in PZ90). ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ ORBIT REPEATABILITY, DAILY SOLUTIONS COMPARED TO 7-DAY-ARC (CM): ------------------------------------------------------------------------------ GLONASS Satellites: 101 106 107 108 109 111 113 115 116 122 ------------------------------------------------------------------------------ 269 10 8 14 12 39 14 8 16 20 11 270 8 7 8 8 34 10 8 10 15 13 271 7 4 9 9 36 8 10 16 18 11 272 9 10 9 14 21 7 11 12 19 10 273 9 7 13 9 40 9 10 16 11 10 274 8 9 8 7 36 9 10 17 23 8 275 7 8 8 10 44 6 9 18 14 17 ------------------------------------------------------------------------------ ALL 8 8 10 10 36 9 10 15 17 12 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 269 270 271 272 273 274 275 STATION ------------------------------------------------------------------------------ BORG 1065.008 1079.327 1078.096 1072.244 1062.674 1060.239 1078.514 0.948 0.950 0.924 0.926 1.010 0.991 0.999 BRUG 1068.137 1084.347 1081.716 1.006 0.987 0.941 CSIR 1064.354 1075.362 1078.378 1073.993 1054.741 1.024 1.033 1.000 0.994 2.228 DLFT -32.020 -20.309 -20.397 -29.502 -40.798 -38.561 -20.533 0.987 0.973 0.945 0.931 1.018 0.997 1.012 GRAB 120.852 134.207 133.741 123.706 113.217 114.188 133.487 1.000 0.997 0.962 0.938 1.056 1.028 1.028 GODZ 127.921 135.386 135.329 127.975 116.691 138.415 1.025 1.010 1.034 1.024 1.046 1.010 HERP 1076.417 1.325 IRKZ 113.234 132.473 133.691 110.876 106.524 134.178 0.999 0.993 0.984 1.112 0.994 0.987 KHAB 107.874 126.679 131.362 117.960 107.723 98.953 128.477 1.023 1.024 1.009 0.959 1.059 0.994 0.980 KR0G 55.001 67.988 69.972 60.428 49.205 42.424 69.835 0.925 0.917 0.897 0.880 0.944 0.926 0.952 LINR 1081.367 1080.854 1068.080 1063.679 1086.350 1.026 0.976 1.068 1.033 1.023 MDVZ 125.297 135.729 138.904 127.536 117.044 113.343 135.897 1.001 0.980 0.937 0.918 0.996 0.995 1.001 METZ 111.075 120.542 125.418 114.083 102.230 95.080 125.524 0.964 0.955 0.937 0.909 0.999 0.992 1.023 MTKA 112.427 132.128 132.741 121.966 113.121 103.484 137.859 1.045 1.037 1.052 0.979 1.048 0.994 0.997 OS0G 110.699 124.286 125.346 114.950 107.678 101.869 123.596 0.960 0.970 0.933 0.921 1.001 0.975 0.985 REYZ 159.365 155.667 149.983 139.080 134.669 153.082 0.951 0.954 0.912 0.984 0.982 0.959 SUNM -21.759 -22.804 -14.996 -43.983 -7.065 1.187 1.168 1.185 1.382 1.128 THU2 123.101 126.734 115.354 106.073 94.473 125.226 0.909 0.902 0.881 0.917 0.933 0.921 USNX 1061.532 1074.485 1071.201 1064.525 1064.279 1054.535 1077.061 1.032 1.031 1.066 1.013 1.013 1.015 1.002 VSLD 1066.070 1081.611 1079.010 1073.766 1062.227 1062.357 1078.894 0.999 0.991 0.982 0.958 1.069 1.025 1.066 WTZZ 127.733 143.706 142.905 133.320 123.330 125.653 138.962 1.001 1.010 0.970 0.958 1.087 1.042 1.028 YARR 135.559 135.488 112.494 142.878 1.013 1.000 1.078 1.052 ZIMZ 87.961 95.146 1.937 1.034 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 269 73844 1929 0.0014 270 95524 2215 0.0014 271 97804 2382 0.0014 272 80237 1962 0.0014 273 70975 2548 0.0014 274 95306 2116 0.0014 275 92647 2097 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1029 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BORG 1 P -
