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: 101 104 106 107 108 109E110E111E113E115E116E120 122 ------------------------------------------------------------------------------ 241 11 9 36 18 19 9 20 14 7 13 27 10 9 242 6 22 41 6 10 9 18 10 15 9 31 27 12 243 8 23 43 10 11 5 15 11 7 15 17 11 11 244 7 11 74 22 8 7 17 14 17 13 20 13 23 245 7 11 52 17 11 7 9 20 11 14 17 11 27 246 11 17 52 19 7 11 15 12 15 10 21 8 13 247 11 -- 57 12 12 15 21 16 10 13 25 7 11 ------------------------------------------------------------------------------ ALL 9 17 52 16 12 10 17 14 12 12 23 14 17 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 241 242 243 244 245 246 247 STATION ------------------------------------------------------------------------------ BIPD 1014.760 1032.711 1017.407 1039.513 1033.297 1036.935 1047.974 0.958 2.304 1.120 0.980 0.978 0.971 1.018 BORG 1011.042 1010.230 1012.091 1033.034 1028.015 1041.749 0.895 0.880 0.878 0.882 0.860 0.924 BRUG 1014.910 1036.102 1029.473 1035.758 1047.830 1.787 0.900 0.858 0.919 0.950 CSIR 1013.226 1013.715 1016.715 1035.260 1022.443 1046.027 0.926 0.954 1.006 0.983 0.971 0.991 DLFT -91.971 -89.984 -88.407 -68.020 -76.652 -72.206 -59.265 0.864 0.846 0.849 0.864 0.844 0.859 0.890 GODZ 71.316 78.424 77.248 87.741 79.066 95.357 103.469 0.898 0.886 0.863 0.886 0.871 0.897 0.931 HERP 1021.619 1048.406 1011.383 1037.334 3.033 3.451 4.710 3.892 IRKZ 68.793 65.704 67.314 79.190 83.335 96.602 0.829 0.788 0.834 0.876 0.862 0.902 KHAB 61.647 62.446 61.584 71.284 81.788 91.555 0.841 0.819 0.844 0.879 0.910 0.926 KR0G -1.863 1.684 -0.999 16.447 15.880 18.881 30.646 0.796 0.779 0.799 0.808 0.794 0.803 0.846 LINR 1019.779 1013.161 1023.148 1028.568 1033.779 1041.564 1051.644 0.899 0.908 0.934 0.951 0.971 0.963 0.955 MDVZ 69.504 69.302 68.451 87.239 84.505 87.147 99.103 0.836 0.821 0.841 0.869 0.830 0.863 0.901 METZ 43.279 24.725 56.760 89.355 84.227 1.705 3.444 1.082 1.246 0.903 MTKA 66.413 75.813 81.699 87.394 93.416 0.849 0.901 0.925 0.931 0.955 OS0G 55.889 57.824 56.672 75.823 71.390 76.444 85.116 0.848 0.830 0.835 0.853 0.822 0.848 0.875 REYZ 83.238 90.194 106.957 100.461 110.050 116.207 1.608 0.825 0.826 0.807 0.836 0.861 SUNM -81.822 -72.301 -64.291 -73.695 -62.924 -53.559 0.949 0.965 0.992 1.037 1.044 1.041 THU2 57.220 58.838 58.740 69.925 71.746 78.726 86.223 0.776 0.770 0.777 0.800 0.777 0.804 0.826 USNX 1008.622 1014.113 1026.545 1017.977 1034.543 1040.723 0.911 0.910 0.913 0.926 0.946 0.992 VSLD 1011.219 1013.164 1011.019 1006.003 1027.738 1031.710 1043.715 0.904 0.886 1.169 0.920 0.879 0.912 1.014 WTZZ 69.922 73.271 74.334 95.851 87.761 91.322 101.782 0.894 0.872 0.882 0.895 0.851 0.877 0.907 ZIMZ 41.181 44.582 46.265 66.624 58.601 60.882 73.344 0.879 0.869 0.873 0.881 0.849 0.895 0.911 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 241 71077 2223 0.0013 242 62426 1942 0.0013 243 86984 2453 0.0014 244 90190 2516 0.0015 245 83408 2366 0.0014 246 84483 2451 0.0014 247 93269 2578 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1025 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 20 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 7 PPPPPPP 16 66 57 BRUG 5 PPPPP 2 5 7 DLFT 7 PPPPPPP 2 2 3 GODZ 7 PPPPPPP -
