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: 101E103E104E106E107E108E109 110 111 113 116 117 120 122 ------------------------------------------------------------------------------ 150 6 7 13 24 10 34 76 -- 24 31 33 14 11 14 151 12 6 12 21 6 55 18 42 13 24 30 17 10 9 152 5 12 15 20 12 28 21 40 22 26 21 13 17 16 153 6 7 13 22 11 52 17 48 27 55 43 25 18 22 154 7 9 13 27 14 81 18 42 31 30 20 13 22 12 155 14 6 10 10 26 45 25 39 30 16 22 17 18 13 156 17 3 10 22 30 49 31 78 43 48 39 24 11 21 ------------------------------------------------------------------------------ ALL 11 8 12 21 18 52 35 50 28 35 31 18 16 16 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 150 151 152 153 154 155 156 STATION ------------------------------------------------------------------------------ BIPD 1069.612 1075.528 1068.228 1071.852 1073.662 1.132 .910 .936 .997 1.353 BORG 1055.997 1068.017 1069.540 1061.760 1066.147 1062.916 1060.770 .906 .813 .832 .860 .868 .700 .882 BRUG 1058.662 1068.520 1071.903 1066.423 1070.043 1067.358 1064.502 .908 .819 .840 .845 .883 .894 .882 CSIR 1057.650 1074.469 1072.045 1069.380 1070.852 1069.470 1070.174 .934 .913 .940 .920 .899 .888 .895 DLFT -43.138 -32.970 -31.556 -38.778 -34.740 -34.818 -36.697 .953 .810 .810 .808 .842 .819 .845 GODZ 115.307 130.817 131.951 128.151 119.873 125.434 128.445 1.182 .975 1.103 .928 1.007 .893 .881 HERP 1071.130 1065.035 .876 .925 KR0G 46.050 56.320 56.338 56.329 56.015 56.821 50.241 .924 .960 .868 .866 .800 .841 .980 LDS1 -874.356 -878.166 -882.597 1.156 1.079 1.120 LINR 1075.600 1073.003 1066.282 1073.209 1075.730 .888 .883 .947 .883 .901 MDVZ 107.630 127.165 124.369 122.352 125.803 126.392 119.223 1.067 .858 .929 .875 .817 .845 1.043 MTKA 103.163 122.128 116.209 116.725 .908 .881 1.009 .883 NPLC 1058.099 1068.257 1066.401 1063.891 1064.885 1058.546 1063.550 .901 .850 .959 .858 1.156 1.278 .890 OS0G 93.001 107.104 103.548 101.059 102.743 101.469 .941 .806 .889 .868 .915 .868 REUN 114.232 131.571 104.067 123.276 113.190 119.355 1.910 1.658 1.562 1.609 1.518 2.572 REYZ 137.802 .973 STRR 105.611 110.799 .948 .974 SUNM -43.462 -25.301 -28.959 -30.262 -30.771 -19.198 -19.354 1.033 1.077 .966 1.013 1.015 .972 .995 THU2 100.929 111.418 113.223 113.068 107.616 113.178 106.353 .833 .817 .865 .856 .850 .875 1.006 USNX 1057.709 1065.636 1065.431 1066.137 1055.384 1061.849 1066.111 .946 .882 .885 .902 .902 .906 .923 VSLD 1057.319 1068.470 1070.246 1071.252 1068.644 1070.774 .921 .849 .862 .966 1.013 1.066 WTZZ 113.825 129.291 127.592 125.546 127.667 122.738 127.462 1.013 .824 .974 .957 .937 .987 1.037 YARR 105.150 123.850 122.623 123.656 132.417 133.915 1.126 1.014 1.094 1.056 .947 1.020 ZIMZ 87.111 99.623 101.192 96.780 97.351 96.735 78.009 .938 .837 .858 .854 .915 .870 2.477 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 150 58488 1979 .0013 151 57880 2219 .0013 152 63366 1930 .0012 153 65369 2062 .0014 154 66759 2149 .0014 155 58225 1744 .0015 156 63893 2081 .0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1012 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 5 PPPPP 13 11 44 BORG 7 PPPPPPP 4 4 8 BRUG 7 PPPPPPP 2 5 8 DLFT 7 PPPPPPP 2 3 5 GODZ 7 PPPPPPP -
