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: 101 103 104 106 107 108 109 110 111 113 115 116 120 122 ------------------------------------------------------------------------------ 206 8 18 15 -- 6 15 20 17 11 15 21 19 7 7 207 9 11 6 -- 9 20 15 33 19 12 22 15 6 10 208 6 30 11 -- 8 9 9 34 21 13 27 16 6 8 209 10 -- 14 -- 10 11 19 27 13 5 28 6 12 13 210 9 -- 24 -- 10 12 11 31 16 17 37 7 10 11 211 9 -- 13 -- 7 6 7 16 14 14 24 7 7 15 212 17 -- 13 -- 13 12 15 20 13 16 29 11 11 13 ------------------------------------------------------------------------------ ALL 10 21 15 -- 9 13 14 26 16 13 28 13 9 11 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 206 207 208 209 210 211 212 STATION ------------------------------------------------------------------------------ 3SNA 1027.541 1052.931 1061.290 1077.254 1077.102 1056.697 1042.646 1.022 1.032 1.036 1.228 1.242 2.234 1.021 BIPD 1052.322 1057.220 1080.217 1085.615 1046.076 1050.248 1.151 0.972 1.152 1.217 1.042 1.030 BORG 1033.450 1048.894 1055.069 1074.897 1077.263 1043.592 0.977 1.045 0.875 1.008 1.070 0.910 BRUG 1039.964 1049.545 1058.028 1078.893 1079.013 1045.131 1048.397 0.892 0.930 0.923 1.028 1.096 1.004 0.936 CSIR 1046.036 1048.007 1056.362 1079.275 1042.715 1051.367 0.982 0.973 0.982 1.157 0.980 1.008 DLFT -62.757 -40.093 -25.133 -57.803 0.863 1.323 1.022 0.906 GODZ 95.569 110.381 115.792 121.341 151.656 105.751 105.499 1.188 0.913 0.929 1.639 1.591 0.946 0.925 HERP 1039.707 1053.258 1060.750 1080.937 1078.375 1046.322 1051.943 1.009 1.059 1.039 1.142 1.175 1.008 1.008 IRKZ 91.259 105.810 103.621 123.168 132.924 96.302 94.432 0.876 0.862 0.853 0.950 1.042 0.864 0.878 KHAB 81.435 102.909 98.829 121.055 89.492 0.893 0.880 0.893 0.969 0.936 KR0G 22.805 35.844 40.887 62.568 65.282 29.550 28.109 0.815 0.793 0.815 1.099 0.985 0.834 0.835 LDS1 -912.613 -901.224 -885.385 -857.200 -857.694 -900.958 -894.842 1.355 1.208 1.217 1.486 1.502 1.362 1.385 LINR 1038.496 1060.662 1061.346 1076.496 1046.203 1055.200 0.937 0.908 0.987 1.086 0.936 1.020 MDVZ 93.177 106.052 107.086 129.451 136.231 99.636 99.387 0.867 0.836 0.847 0.963 1.011 0.879 0.874 MTKA 84.953 105.881 99.871 120.809 127.373 93.286 94.430 0.901 0.884 0.923 0.989 1.054 0.887 0.916 NPLC 1029.096 1069.974 1.364 1.436 OS0G 81.345 89.174 99.047 119.922 123.149 82.933 87.743 0.924 0.907 0.904 1.060 1.106 0.948 0.938 REYZ 109.722 125.699 130.826 148.860 156.131 117.218 120.771 0.869 0.874 0.871 0.950 0.990 0.891 0.896 THU2 78.888 98.345 98.958 111.083 123.832 88.103 86.719 0.803 0.805 1.061 1.049 1.086 0.814 0.809 USNX 1029.474 1075.698 1042.578 1045.109 0.941 1.105 0.985 0.971 VSLD 1036.325 1046.451 1067.307 1075.477 1041.049 1044.649 0.920 0.921 1.273 1.105 0.986 0.977 WTZG -704.053 2.888 WTZZ 99.956 107.028 113.387 131.650 135.860 101.268 103.469 0.886 0.876 0.889 1.000 1.057 0.944 0.941 YARR 99.609 104.085 109.230 122.843 133.751 99.692 105.407 0.890 0.886 0.948 0.973 1.078 0.918 0.952 ZIMZ 68.635 76.832 85.556 104.838 107.962 73.930 76.863 0.870 0.859 0.871 0.981 1.053 0.933 0.914 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 206 94888 2883 0.0015 207 85773 2765 0.0016 208 84056 2676 0.0016 209 72516 2270 0.0016 210 76946 2103 0.0015 211 45962 1788 0.0016 212 91414 2566 0.0016 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1020 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 21 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 7 PPPPPPP 149 189 154 BIPD 6 PPPPPP 5 16 19 BORG 2 PP 2 45 9 BRUG 7 PPPPPPP 3 4 5 DLFT 4 P P P P 1 1 4 GODZ 7 PPPPPPP -
