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 ------------------------------------------------------------------------------ 199 7 22 16 70 13 11 12 18 12 22 22 25 14 13 200 8 14 15 64 12 16 13 14 7 14 16 22 10 9 201 9 30 6 24 15 9 20 22 10 9 17 13 15 10 202 6 22 29 60 14 15 15 10 24 10 9 11 19 9 203 6 21 11 43 8 11 11 18 17 12 22 15 14 12 204 5 21 10 67 8 9 5 7 15 7 22 18 13 7 205 9 15 14 55 23 22 16 12 8 9 23 20 19 8 ------------------------------------------------------------------------------ ALL 7 21 16 57 14 14 14 15 15 13 19 18 15 10 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 199 200 201 202 203 204 205 STATION ------------------------------------------------------------------------------ 3SNA 1021.203 1020.520 1050.396 1019.138 1027.541 1024.047 1020.011 1.136 1.113 3.435 0.923 0.951 0.976 1.053 BIPD 1019.565 1024.585 1030.214 1023.619 1.125 1.082 0.983 3.004 BORG 1013.656 1022.699 1017.081 1021.335 1025.098 1023.182 1025.308 0.852 0.849 0.875 0.876 0.876 0.917 0.895 BRUG 1016.023 1019.296 1023.884 1024.451 1025.048 1027.779 0.912 0.867 0.902 0.905 0.916 0.927 CSIR 1017.900 1028.777 1024.580 1028.392 1028.222 1024.972 1039.157 0.934 0.927 0.897 0.896 0.964 0.982 0.928 DLFT -87.451 -77.853 -81.517 -76.556 -72.864 -75.489 -75.592 0.823 0.827 0.833 0.845 0.839 0.879 0.888 GODZ 71.488 93.430 80.887 82.812 87.177 83.533 82.762 1.042 5.815 0.894 0.865 0.864 0.865 0.913 HERP 1015.063 1022.847 1019.615 1024.884 1030.231 1032.121 1035.243 0.890 0.932 0.896 0.902 0.911 0.997 1.006 IRKZ 69.127 79.058 71.036 75.148 75.761 80.397 81.023 0.844 0.815 0.840 0.829 0.826 0.857 0.868 KHAB 66.632 76.778 69.590 71.662 71.930 76.190 74.380 0.840 0.833 0.853 0.847 0.825 0.869 0.882 KR0G 1.635 13.042 7.137 9.288 12.524 9.741 12.166 0.761 0.783 0.774 0.791 0.769 0.801 0.804 LDS1 -932.274 -922.521 -924.430 -925.330 -923.414 -921.757 1.170 1.165 1.198 1.248 1.216 1.293 LINR 1035.813 1021.879 1026.848 1036.730 1036.960 1038.637 0.922 0.886 0.871 0.906 0.943 0.946 MDVZ 71.452 82.386 76.655 83.019 82.100 79.961 0.803 0.798 0.813 0.815 0.860 0.855 MTKA 69.115 81.942 71.201 72.918 74.766 80.530 75.628 0.846 0.874 0.880 0.852 0.835 0.880 0.883 OS0G 55.493 67.423 66.748 71.206 67.774 65.526 67.887 1.063 0.854 0.859 0.897 0.883 0.936 0.944 REYZ 97.676 97.044 100.739 101.470 99.695 100.013 0.831 0.830 0.843 0.821 0.860 0.861 SUNM -77.919 -77.636 -72.849 1.030 0.918 0.920 THU2 58.060 70.078 63.392 68.229 73.402 69.228 70.122 0.752 0.783 0.784 0.788 0.774 0.819 0.794 USNX 1009.912 1021.782 1014.632 1017.022 1023.703 1017.049 1017.888 0.913 0.943 0.941 0.887 0.903 0.921 0.976 VSLD 1013.887 1020.940 1016.391 1021.117 1023.894 1022.359 1024.473 0.857 0.867 0.881 0.904 0.902 0.940 0.927 WTZZ 73.777 82.830 79.684 84.234 86.444 85.822 88.557 0.836 0.839 0.862 0.865 0.864 0.892 0.904 YARR 86.208 89.141 0.971 0.898 ZIMZ 45.070 54.318 50.216 55.561 58.375 57.343 56.913 0.840 0.833 0.849 0.858 0.852 0.889 0.881 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 199 79067 2465 0.0015 200 80173 2561 0.0016 201 98067 2714 0.0016 202 86463 2656 0.0016 203 97332 2796 0.0017 204 94560 2857 0.0015 205 95449 3141 0.0015 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1019 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 6 PP PPPP 24 119 151 BIPD 3 P PP 4 6 45 BORG 7 PPPPPPP 3 5 17 BRUG 7 PPPPPPP 4 7 12 DLFT 7 PPPPPPP 1 3 4 GODZ 6 P PPPPP -
