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-96: 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: 101 103 104 106 107 108 109 110 111 113 115 116 117E120E122E ------------------------------------------------------------------------------ 171 12 12 13 19 18 79 41 70 46 66 0 35 20 10 17 172 12 11 19 19 40 126 75 34 41 27 0 55 24 8 12 173 31 16 14 18 34 77 21 17 16 37 0 51 33 7 15 174 24 20 17 17 15 34 15 43 19 20 0 23 19 10 11 175 11 19 29 14 12 21 18 20 27 45 0 31 25 14 12 176 16 14 18 20 13 19 32 21 19 19 22 81 21 11 12 177 16 15 29 17 11 22 38 34 23 32 23 58 18 20 10 ------------------------------------------------------------------------------ ALL 19 16 21 18 23 66 39 38 29 38 22 51 23 12 13 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 171 172 173 174 175 176 177 STATION ------------------------------------------------------------------------------ 3SNA 1044.912 1032.659 1048.228 1045.896 0.958 1.954 0.954 0.909 BIPD 1046.492 1047.726 1047.012 1051.791 0.955 0.978 0.983 0.918 BORG 1041.731 1043.504 1041.873 1043.709 1046.438 1041.644 1051.041 0.861 1.205 0.885 0.843 0.871 1.271 1.094 BRUG 1045.544 1044.847 1045.126 1047.912 1048.909 1045.630 1050.140 0.870 0.907 0.899 0.844 0.829 0.834 0.843 CSIR 1048.836 1045.507 1050.281 1050.146 1053.983 1051.382 1055.332 0.933 0.921 0.937 0.941 0.928 0.893 0.857 DLFT -57.734 -51.215 -54.894 -54.495 -54.864 -59.162 -53.907 0.874 0.879 0.910 0.860 0.826 0.826 0.838 GODZ 100.163 104.113 106.154 104.336 103.521 86.957 104.822 1.130 1.096 0.977 1.067 0.924 2.401 0.868 HERP 1041.704 1052.558 1049.129 1050.839 1050.930 1046.303 1053.823 0.993 0.996 0.939 0.889 0.858 0.921 0.909 KHAB 94.790 96.415 100.074 90.221 97.156 89.410 92.228 0.999 0.855 0.928 0.858 1.050 0.859 1.245 KR0G 15.258 40.011 31.591 22.034 32.453 28.536 33.239 3.567 0.941 0.910 1.627 0.748 0.759 0.756 LDS1 -901.473 -887.437 -893.938 -890.962 1.114 1.113 1.083 1.095 LINR 1047.157 1053.509 1056.962 1042.690 1049.484 1058.428 0.904 0.891 0.919 0.916 1.293 0.876 MDVZ 95.040 98.608 1.550 0.957 MTKA 97.435 89.656 98.807 86.370 96.390 90.825 92.269 1.072 1.110 1.036 1.063 0.921 0.872 0.916 NPLC 1042.452 1044.167 1041.410 1045.540 1048.407 1044.803 1047.606 0.899 0.907 0.922 0.858 0.859 0.839 0.856 OS0G 79.524 81.773 74.847 81.879 83.291 80.926 88.432 0.914 0.992 1.011 0.888 0.830 0.856 0.915 REYZ 115.482 123.674 117.491 118.599 122.059 111.430 119.543 0.993 0.864 0.877 0.907 1.005 1.027 0.997 SUNM -46.339 -41.586 -36.030 -52.241 -45.096 -32.815 -37.238 0.960 0.897 0.968 1.025 0.981 0.934 0.935 THU2 85.039 93.659 91.165 87.710 93.377 86.271 0.951 0.805 0.886 0.825 0.996 0.778 USNX 1037.437 1046.157 1042.541 1041.297 1040.899 1042.834 1043.987 0.919 0.927 0.924 0.943 0.896 0.902 0.860 VSLD 1042.775 1044.116 1043.538 1045.535 1046.783 1043.199 1047.317 0.883 0.892 0.902 0.857 0.832 0.852 0.844 WTZG -710.164 0.997 WTZZ 103.231 103.295 0.992 0.979 YARR 105.786 103.151 102.336 92.058 107.254 112.760 111.935 0.975 1.033 0.960 0.959 1.115 1.121 0.925 ZIMZ 71.532 77.121 75.723 76.418 73.169 71.829 76.176 0.936 1.002 1.041 0.968 0.910 0.912 0.904 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 171 59418 2347 0.0014 172 69693 2296 0.0014 173 65446 2230 0.0015 174 59407 2350 0.0014 175 38619 1793 0.0013 176 51895 1664 0.0013 177 52657 1463 0.0015 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1015 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 2 P P 1 186 10 BIPD 4 PPPP 4 12 25 BORG 6 PPPPPP 2 9 24 BRUG 5 PPPPP 3 3 9 DLFT 7 PPPPPPP 1 2 4 GODZ 7 PPPPPPP -
