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 109E111E113E115E116E120 122 ------------------------------------------------------------------------------ 248 9 45 29 7 14 5 13 10 65 60 14 249 11 48 24 8 11 7 8 8 57 59 15 250 7 59 28 14 6 13 15 8 63 47 15 251 8 56 42 9 6 6 13 9 84 90 17 252 10 122 68 31 12 15 16 17 177 148 56 253 13 199 98 33 14 7 15 16 130 142 47 254 11 202 61 26 10 10 13 11 124 -- 29 ------------------------------------------------------------------------------ ALL 10 123 56 21 11 10 14 12 108 100 32 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 248 249 250 251 252 253 254 STATION ------------------------------------------------------------------------------ BIPD 1051.809 1050.507 1056.843 1066.024 1.131 1.072 1.064 1.071 BORG 1045.522 1043.314 1046.425 1051.794 1057.406 0.932 0.939 0.965 1.038 0.975 BRUG 1038.980 1049.968 1047.111 1049.954 1055.223 1061.884 1.096 1.045 1.013 0.986 1.000 1.012 CSIR 1044.144 1046.455 1048.231 1049.710 371848.204 1.010 0.967 1.032 1.667 4978.844 DLFT -67.245 -56.422 -58.358 -57.341 -49.654 -43.112 0.909 0.943 0.916 0.956 0.960 1.003 GODZ 93.467 105.648 106.577 103.252 109.605 0.990 1.035 0.951 0.937 0.984 IRKZ 84.726 90.688 94.730 101.651 105.074 107.623 0.898 0.913 0.890 0.929 0.905 1.020 KHAB 78.245 84.166 92.167 95.066 102.661 102.986 0.927 0.928 0.913 0.931 0.921 1.026 KR0G 23.880 30.175 33.224 34.154 42.812 43.423 0.857 0.872 0.851 0.879 0.889 0.940 LINR 1040.781 1047.948 1057.151 1072.830 1.018 0.966 1.076 1.050 MDVZ 91.886 101.444 101.306 103.443 110.806 113.315 0.905 0.911 0.895 0.934 0.952 1.018 METZ 76.544 84.876 89.713 92.417 98.401 102.439 0.889 0.911 0.897 0.937 0.946 1.015 MTKA 82.451 90.905 96.222 103.060 104.381 108.681 0.944 0.935 0.939 0.941 0.931 1.038 OS0G 82.139 89.944 88.245 90.347 95.023 100.700 0.896 0.936 0.891 0.926 0.940 0.989 REYZ 117.771 119.538 119.944 119.442 129.048 0.920 0.871 0.883 0.916 0.969 SUNM -65.179 -58.110 -50.585 -55.934 -47.585 -40.236 1.082 1.055 1.072 1.061 1.142 1.212 THU2 76.318 83.758 86.851 88.607 94.339 96.700 0.857 0.875 0.820 0.841 0.854 0.935 USNX 1035.154 1043.440 1041.987 1043.202 1050.603 1047.911 1.015 1.060 1.038 0.987 1.000 1.059 VSLD 1037.562 1044.903 1044.499 1045.626 1050.872 1058.398 0.962 1.002 0.967 1.002 1.031 1.005 WTZZ 96.304 106.253 104.063 105.324 109.299 120.091 0.917 0.985 0.931 0.989 0.990 1.023 ZIMZ 66.873 74.838 76.076 77.401 81.057 88.148 0.925 0.968 0.941 0.974 0.975 1.017 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 248 86369 2200 0.0014 249 94934 2514 0.0014 250 88913 2247 0.0014 251 91048 2355 0.0014 252 88631 2510 0.0015 253 85167 2213 0.0015 254 82038 2175 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1026 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 20 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 5 PPPPP 2 6 36 BRUG 7 PPPPPPP 3 3 12 DLFT 7 PPPPPPP 1 3 6 GODZ 6 PPPPP P -
