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 120E122E ------------------------------------------------------------------------------ 192 11 8 89 20 9 9 27 16 24 19 38 53 37 19 193 8 7 177 15 13 12 12 16 21 16 17 74 35 9 194 8 12 101 18 16 10 16 39 17 12 22 69 45 16 195 13 8 103 10 12 15 11 29 11 7 17 31 22 10 196 4 11 50 18 6 13 23 24 17 13 25 43 23 11 197 13 10 75 8 18 9 17 16 14 19 17 31 18 9 198 12 10 70 15 7 11 32 27 16 23 21 50 18 13 ------------------------------------------------------------------------------ ALL 10 10 102 15 12 11 21 25 18 16 24 53 30 13 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 192 193 194 195 196 197 198 STATION ------------------------------------------------------------------------------ 3SNA 1004.272 989.465 1006.851 1005.320 1015.943 1027.389 1005.570 1.193 1.133 1.135 1.087 1.052 1.061 1.066 BIPD 1003.783 1012.680 1013.730 1.040 0.958 0.989 BORG 997.526 997.075 1005.736 1011.840 1013.180 1020.045 1007.976 0.887 0.854 1.015 1.067 0.882 0.852 0.860 BRUG 1001.215 999.197 1009.904 1012.105 1015.571 1024.628 1009.920 0.916 0.847 0.888 0.947 0.878 0.867 0.865 CSIR 1017.362 1016.590 1022.644 1024.169 1012.661 0.903 0.971 0.947 0.888 0.931 DLFT -101.695 -102.418 -91.805 -91.291 -84.739 -77.946 -92.047 0.847 0.809 0.825 0.853 0.823 0.823 0.815 GODZ 60.052 58.495 72.862 68.729 74.142 89.732 68.738 0.895 0.900 0.909 0.909 0.876 0.861 0.869 HERP 1002.729 1000.237 1011.810 1006.215 1016.061 1025.202 1011.400 0.956 0.893 0.917 1.007 0.901 0.910 0.860 IRKZ 53.258 54.564 79.280 67.302 69.867 72.598 63.260 0.879 0.826 3.227 0.844 0.852 0.841 0.821 KHAB 47.325 48.795 60.802 63.236 67.262 68.153 57.128 0.882 0.818 0.850 0.844 0.855 0.838 0.833 KR0G -12.071 -12.494 -5.800 -3.143 3.135 8.969 -1.700 0.795 0.759 0.784 0.799 0.780 0.779 0.767 LDS1 -957.008 -939.427 -937.078 -938.276 -929.082 -919.451 -935.739 1.667 1.079 1.134 1.237 1.215 1.230 1.219 LINR 1007.312 1007.560 1018.980 1018.158 1029.275 1027.526 1009.973 0.938 1.395 0.874 0.909 0.925 0.912 0.878 MDVZ 57.705 58.279 64.916 66.902 73.699 77.959 65.812 0.844 0.789 0.820 0.834 0.817 0.820 0.804 MTKA 49.268 49.571 65.463 66.463 70.387 72.788 59.273 0.899 0.860 0.861 0.872 0.870 0.848 0.831 NPLC 1002.063 997.801 1008.606 1007.149 1013.474 1028.144 1.029 0.858 0.917 0.949 0.891 1.418 OS0G 47.198 44.857 50.244 51.952 60.034 64.119 54.577 0.870 0.825 0.876 0.882 0.859 0.850 0.871 REUN 58.216 1.628 REYZ 97.985 81.600 0.952 0.813 SUNM -77.800 -96.031 -81.622 -84.689 -74.261 -75.507 -91.102 1.024 0.920 0.931 0.926 0.918 0.958 0.952 THU2 46.382 43.961 56.633 54.763 58.313 67.526 54.049 0.798 0.765 0.791 0.796 0.780 0.773 0.761 USNX 997.616 991.223 1007.163 1003.587 1012.386 0.921 0.929 0.928 0.952 0.944 VSLD 998.503 996.252 1006.250 1006.664 1014.083 1021.182 1007.881 0.915 0.863 0.912 0.944 0.894 0.870 0.852 WTZZ 66.338 70.987 72.568 81.518 69.146 1.164 0.885 0.858 0.838 0.837 YARR 60.227 58.127 73.013 0.899 0.874 0.892 ZIMZ 31.333 32.007 43.893 42.869 46.403 54.220 40.058 0.864 0.837 1.402 0.991 0.877 0.851 0.848 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 192 82391 2523 0.0015 193 82028 2551 0.0016 194 75689 2593 0.0015 195 84851 2989 0.0016 196 84058 2743 0.0016 197 88176 2828 0.0016 198 90381 2735 0.0016 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1018 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 24 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 7 PPPPPPP 12 82 110 BIPD 3 PPP 4 2 24 BORG 7 PPPPPPP 3 9 23 BRUG 7 PPPPPPP 2 6 12 DLFT 7 PPPPPPP 3 2 6 GODZ 7 PPPPPPP -
