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 117E120E122E ------------------------------------------------------------------------------ 178 7 16 18 26 23 59 58 67 23 48 26 46 23 12 18 179 11 7 40 16 27 65 17 56 14 23 29 37 21 13 14 180 12 12 19 14 21 39 28 27 21 48 54 42 18 18 16 181 13 14 28 20 19 26 36 35 9 29 20 24 22 17 17 182 18 10 17 21 22 45 11 55 12 36 51 44 17 12 5 183 17 6 19 16 14 24 17 24 39 22 27 44 32 12 23 184 17 23 27 24 15 26 28 59 11 27 37 23 41 12 14 ------------------------------------------------------------------------------ ALL 14 14 25 20 21 43 32 49 21 35 37 38 26 14 16 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 178 179 180 181 182 183 184 STATION ------------------------------------------------------------------------------ 3SNA 1051.094 1052.132 1028.748 1028.994 0.908 0.878 0.911 0.994 BIPD 1046.872 1035.055 1027.164 1.008 0.918 2.149 BORG 1052.412 1049.762 1045.932 1046.795 1026.678 1028.193 1024.785 0.796 0.838 0.839 0.838 0.857 0.868 0.839 BRUG 1055.938 1054.420 1048.417 1049.911 1031.695 1031.238 1028.851 0.814 0.894 0.847 0.865 0.853 0.860 0.867 CSIR 1062.789 1054.681 1051.958 1048.061 1034.896 1040.651 1043.023 0.889 0.902 0.874 0.915 0.904 0.923 0.954 DLFT -48.619 -48.879 -53.334 -52.477 -70.168 -72.384 -75.885 0.996 0.850 0.848 0.891 0.857 0.828 0.843 GODZ 117.474 109.895 107.494 90.705 75.142 1.058 1.036 1.072 0.981 1.780 HERP 1059.559 1053.069 1048.898 1049.321 1032.628 1030.389 1031.423 0.835 0.868 0.863 0.898 0.852 0.856 0.867 KHAB 101.674 97.390 95.737 74.018 81.875 79.108 0.821 0.829 0.838 0.834 1.030 0.838 KR0G 37.678 31.327 34.209 35.974 19.724 26.022 12.635 0.883 0.902 0.809 0.850 1.515 1.782 0.892 LDS1 -914.511 -911.504 -913.827 1.168 1.109 1.131 LINR 1059.965 1056.545 1035.620 1048.471 1045.285 0.862 0.853 0.883 0.879 0.872 MDVZ 114.250 98.772 104.702 103.133 84.951 87.688 80.569 1.835 1.209 0.902 0.855 0.979 0.824 0.997 MTKA 103.562 99.421 99.742 94.868 77.534 85.346 78.023 0.905 0.827 0.953 0.956 0.864 1.048 0.843 NPLC 1055.344 1052.870 1046.881 1046.527 1030.089 1027.488 1029.050 0.822 0.843 0.859 0.863 0.877 0.864 0.867 OS0G 99.011 89.570 87.968 93.565 70.040 78.625 69.966 0.792 0.871 0.912 1.097 1.935 2.711 0.839 REYZ 120.547 121.464 125.480 119.106 103.787 107.352 99.369 0.884 0.928 0.849 0.820 0.976 0.811 0.880 SUNM -29.971 -34.158 -37.859 -36.086 -53.698 -48.296 -51.494 0.918 0.901 0.880 0.947 0.954 0.939 0.911 THU2 87.963 88.234 68.499 74.114 70.121 1.199 0.781 0.803 0.813 0.783 USNX 1050.457 1050.984 1047.273 1040.437 1024.746 1022.041 1026.601 0.870 0.852 0.895 0.891 0.887 0.901 0.928 VSLD 1053.514 1051.817 1044.665 1028.704 1023.204 1025.398 1.086 0.834 1.067 0.954 1.214 0.874 ZIMZ 83.363 82.236 79.770 87.609 65.506 59.882 55.046 0.850 0.813 0.896 1.049 0.989 0.830 0.926 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 178 41669 1529 0.0015 179 46232 1692 0.0014 180 54688 1871 0.0015 181 55182 1744 0.0015 182 56186 2115 0.0016 183 56177 2110 0.0015 184 41980 1798 0.0015 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1016 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 20 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 2 PP 114 28 36 BIPD 1 P -
