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 ------------------------------------------------------------------------------ 227 11 10 30 21 20 17 16 9 17 20 18 14 12 228 7 6 24 7 22 16 18 6 16 20 16 23 15 229 14 12 33 20 11 13 14 13 18 29 24 26 13 230 13 12 29 23 46 16 23 10 13 27 24 15 18 231 20 15 44 23 55 13 40 34 18 25 35 13 27 232 26 27 40 26 22 13 57 23 11 23 17 13 16 233 11 21 37 24 28 10 39 17 10 22 19 30 16 ------------------------------------------------------------------------------ ALL 16 16 34 21 32 14 33 18 15 24 23 20 17 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 227 228 229 230 231 232 233 STATION ------------------------------------------------------------------------------ BORG 1049.672 1056.064 1049.997 1048.818 1034.173 1037.795 1026.207 0.912 0.887 0.882 0.862 0.862 0.903 0.889 BRUG 1054.277 1059.578 1053.253 1051.819 1038.817 1042.193 1028.959 0.937 0.921 0.899 0.887 0.906 0.938 0.919 CSIR 1050.946 1060.967 1053.415 1053.972 1034.353 0.990 0.965 0.979 0.949 0.923 DLFT -50.453 -46.939 -52.278 -54.868 -68.253 -64.904 -77.078 0.881 0.866 0.866 0.842 0.845 0.877 0.862 HERP 1056.165 1059.337 1052.069 1052.671 1037.446 1042.127 1026.908 0.988 1.045 0.945 0.923 1.159 1.087 1.028 IRKZ 99.604 107.042 102.448 100.994 0.834 0.871 0.909 0.833 KHAB 96.171 102.613 72.196 0.846 0.880 0.843 KR0G 37.583 41.124 37.210 35.604 23.793 0.815 0.797 0.831 0.771 1.426 LINR 1067.163 1062.774 1041.602 1037.035 1030.688 0.989 0.983 0.981 0.903 0.950 MDVZ 106.601 111.612 103.934 81.719 0.862 0.844 0.880 0.841 MTKA 99.970 104.824 102.062 103.986 75.826 0.873 0.889 0.944 0.901 0.873 OS0G 95.530 98.376 93.026 91.623 78.543 81.471 70.315 0.857 0.838 0.903 0.817 0.829 0.856 0.849 REYZ 127.952 134.330 130.872 126.502 108.449 108.738 99.448 0.861 0.871 0.859 0.845 0.866 0.898 0.852 SUNM -51.527 -56.948 1.037 1.140 THU2 92.656 94.917 88.381 79.680 79.099 70.068 0.812 0.830 0.798 0.793 0.826 0.781 USNX 1019.423 0.924 VSLD 1052.402 1055.381 1049.250 1037.151 1025.881 1018.700 0.980 0.952 0.904 1.268 1.151 1.240 WTZG -699.632 -703.803 -706.586 -713.538 -727.460 1.438 1.730 1.249 1.483 1.285 WTZZ 109.181 117.427 110.229 108.794 95.066 98.979 88.122 0.894 0.959 0.903 0.856 0.870 0.898 0.893 YARR 98.181 120.062 112.611 105.700 95.895 90.312 82.385 0.913 0.933 0.914 0.893 0.919 0.880 0.877 ZIMZ 104.785 65.733 68.850 58.514 5.191 1.106 0.902 0.891 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 227 85295 2278 0.0016 228 77837 2290 0.0015 229 67980 2001 0.0015 230 51809 1405 0.0014 231 43795 1453 0.0013 232 46193 1249 0.0014 233 73185 1960 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1023 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 17 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BRUG 7 PPPPPPP 4 3 11 DLFT 7 PPPPPPP 2 2 4 HERP 7 PPPPPPP 26 38 79 IRKZ 4 PPPP -
