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: 101 104 106 107 108 109 110 111 113 115 116 120 122 ------------------------------------------------------------------------------ 220 12 16 72 93 9 13 17 10 10 27 21 18 33 221 12 14 27 116 10 8 7 8 9 21 25 21 45 222 11 9 26 111 17 10 17 7 10 40 24 14 50 223 20 10 14 161 12 12 23 16 9 31 22 19 56 224 17 10 14 57 8 12 24 16 9 24 14 15 21 225 15 8 20 64 12 9 27 13 10 30 17 16 23 226 25 16 21 61 14 11 24 18 12 26 16 10 26 ------------------------------------------------------------------------------ ALL 17 13 33 101 12 11 21 13 10 29 20 17 39 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 220 221 222 223 224 225 226 STATION ------------------------------------------------------------------------------ 3SNA 1053.057 1063.599 1041.402 1037.664 1039.111 1.024 1.005 1.021 1.029 1.007 BIPD 1053.531 1068.648 1050.402 1048.275 1047.191 1027.561 3.341 1.155 1.031 0.973 0.991 1.033 BORG 1052.307 1064.112 1043.581 1039.216 1043.326 1043.596 1023.724 0.926 0.870 0.862 0.878 0.982 1.070 0.905 BRUG 1057.149 1068.306 1046.869 1043.384 1044.195 1044.873 1026.254 0.959 0.881 0.883 0.899 0.935 0.938 0.966 CSIR 1054.530 1073.565 1049.110 1044.669 1042.551 1036.652 1033.235 0.978 0.972 0.962 0.978 0.928 0.916 0.970 DLFT -48.343 -36.429 -58.340 -62.109 -60.563 -62.379 -78.029 0.864 0.862 0.853 0.850 0.870 0.862 0.884 GODZ 99.535 1.248 HERP 1055.240 1070.860 1047.415 1043.743 1047.373 1041.747 1024.004 0.970 0.960 0.942 0.962 1.014 0.982 1.061 IRKZ 112.120 121.919 95.904 87.884 84.407 91.956 82.544 0.855 0.874 0.855 0.844 1.302 0.834 0.839 KHAB 119.376 97.901 84.389 80.350 86.867 80.233 0.887 0.902 0.874 0.908 0.867 0.860 KR0G 39.718 54.965 32.916 26.792 25.788 27.494 11.961 0.795 0.806 0.798 0.826 0.821 0.801 0.801 LDS1 -900.107 -876.797 -899.358 -902.868 -893.990 1.760 1.235 1.222 1.242 2.079 LINR 1073.849 1051.674 1056.937 0.934 0.966 0.999 MDVZ 111.255 122.377 100.287 94.458 94.988 81.525 0.848 0.851 0.848 0.833 0.939 0.862 MTKA 109.305 118.900 100.737 86.909 85.844 89.323 82.335 0.874 0.890 0.920 0.886 0.939 0.896 0.865 OS0G 97.961 106.440 85.010 82.429 83.542 82.969 68.888 1.236 0.849 0.832 0.838 0.837 0.844 0.860 REUN 65.310 90.927 2.128 1.584 REYZ 141.874 120.823 113.314 114.396 115.520 101.421 1.243 0.850 0.865 0.871 0.869 0.878 SUNM -39.258 -32.061 -56.541 -42.599 -53.328 -55.201 -67.304 0.961 1.007 1.037 1.047 0.948 1.047 1.306 THU2 98.154 112.583 91.101 81.297 80.862 86.955 70.560 0.776 0.800 0.784 0.821 0.816 0.846 0.838 USNX 1047.457 1061.592 1042.426 1039.542 1033.913 1038.563 0.944 0.944 0.950 0.982 0.973 0.945 VSLD 1052.248 1064.557 1042.978 1039.782 1044.766 1041.527 1023.460 0.947 0.922 0.919 0.948 1.155 0.962 0.999 WTZG -725.982999284.381 999284.481 2.171 1.072 0.988 WTZZ 114.580 124.219 103.149 98.158 103.391 101.592 87.275 0.896 0.883 0.874 0.888 0.899 0.903 0.931 YARR 110.985 125.036 104.682 103.110 94.944 92.571 92.452 0.912 0.917 0.925 0.919 0.890 0.864 0.889 ZIMZ 82.909 95.944 77.077 70.852 73.755 72.573 54.430 0.879 0.870 0.867 0.874 0.880 0.882 0.902 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 220 75201 2096 0.0015 221 91701 2613 0.0016 222 93738 2748 0.0016 223 103362 2811 0.0015 224 82960 2266 0.0013 225 35149 1572 0.0013 226 92649 2476 0.0016 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1022 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 6 PPPPPP 132 133 233 BIPD 7 PPPPPPP 13 17 105 BRUG 7 PPPPPPP 3 7 8 DLFT 7 PPPPPPP 1 3 5 GODZ 1 P -
