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: IRKZ OS0G YARR ZIMZ. 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: 101E103E104E106E107E108E109 110 111 113 116 117 120 122 ------------------------------------------------------------------------------ 129 13 11 11 18 16 18 21 28 21 18 29 15 10 12 130 8 10 13 12 12 16 14 9 18 39 19 15 4 16 131 6 13 8 17 12 14 22 17 14 40 22 17 10 11 132 15 11 18 16 9 30 21 15 16 16 17 13 12 9 133 19 8 11 15 11 21 39 20 24 21 48 8 17 12 134 8 14 10 15 17 15 27 24 27 14 12 11 13 9 135 9 20 10 16 12 17 20 23 20 18 15 11 11 13 ------------------------------------------------------------------------------ ALL 12 13 12 16 13 19 25 20 20 26 26 13 11 12 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 129 130 131 132 133 134 135 STATION ------------------------------------------------------------------------------ 3SNA 1029.079 1038.725 1041.094 1052.819 1037.232 1048.089 .903 .943 .938 .917 .909 .886 BIPD 1040.377 1040.712 1044.934 1052.637 1044.571 1055.945 1057.686 .893 .913 1.077 1.028 .938 .947 .905 BORG 1033.470 1035.506 1038.944 1047.766 1041.397 1049.437 1051.355 .848 .834 .857 .843 .835 .848 .828 BRUG 1036.342 1039.037 1041.935 1054.060 1043.483 1054.224 1055.702 .834 .840 .886 .846 .853 .862 .838 CSIR 1040.089 1040.606 1043.091 1045.490 1048.250 1053.693 .893 .934 1.461 1.329 .924 .934 DLFT -68.690 -66.035 -61.812 -48.352 -59.585 -49.375 -48.254 .828 .804 .895 .832 .830 .847 .851 GODZ 89.556 95.023 92.682 107.041 97.537 106.810 112.606 .908 .974 1.020 .915 1.037 1.820 .841 HERP 1037.329 1038.343 1040.997 1053.050 1045.214 1053.794 .847 .953 .923 1.037 .934 .967 IRKZ 100.412 92.722 1.036 .831 KR0G 25.379 24.037 30.047 36.715 27.850 35.222 40.123 .837 .824 .904 .838 .826 .822 .803 LDS1 -910.286 -910.011 -901.570 -888.222 -902.861 -892.880 -892.915 1.048 1.101 1.599 1.074 1.154 1.110 1.167 MDVZ 94.215 87.994 100.452 104.090 95.329 105.524 107.096 .877 .905 .865 .846 .829 .948 .993 MTKA 87.290 84.224 90.674 98.639 90.118 100.045 101.164 .871 .828 .935 .947 .813 .845 .899 NPLC 1039.650 1041.261 1063.012 1041.736 1053.887 1054.272 1.090 .895 1.163 .852 1.357 .877 OS0G 70.255 68.864 75.883 85.275 68.927 87.394 87.113 .920 .896 .874 .968 2.356 .882 .847 STRR 59.417 77.332 80.012 71.609 78.450 88.836 .998 .923 .913 .880 .910 .970 SUNM -45.737 .981 THU2 77.314 80.908 86.226 95.045 76.876 89.840 97.877 .833 .801 .857 .806 2.955 .910 .819 TSKA 71.697 83.897 87.200 79.920 1.005 .937 .941 .813 USNX 1025.832 1035.511 1034.976 1050.982 1045.478 1053.216 .891 .896 .908 .885 .883 .895 VSLD 1035.965 1035.088 1039.813 1053.741 1045.026 1052.547 1052.906 .859 .856 .888 .876 .851 .875 .846 WTZG 999295.835 .979 WTZZ 87.806 99.521 106.832 101.779 114.769 115.698 .987 .897 .997 .998 .948 .990 YARR 95.910 94.984 105.991 105.632 97.325 100.134 107.000 1.135 .887 .852 .919 .845 .965 .979 ZIMZ 66.181 62.281 70.567 79.374 72.025 80.919 85.081 .932 .928 .892 .924 .899 .854 .898 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 129 56029 2009 .0013 130 77147 2481 .0014 131 70642 2710 .0012 132 77819 2444 .0014 133 75325 2277 .0015 134 66504 2262 .0013 135 69236 2219 .0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1009 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 6 PPPPPP 130 33 686 BIPD 7 PPPPPPP 4 11 19 BORG 7 PPPPPPP 3 7 15 BRUG 7 PPPPPPP 1 7 11 DLFT 7 PPPPPPP 1 2 7 GODZ 7 PPPPPPP 12 20 11 HERP 6 PPPPPP 13 8 29 IRKZ 2 PP -
