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 ------------------------------------------------------------------------------ 213 9 10 -- 17 5 10 18 15 10 17 27 10 19 214 8 10 -- 15 20 16 26 8 5 6 20 7 7 215 7 12 -- 13 7 14 18 8 7 7 12 6 13 216 8 14 -- 17 26 8 42 14 9 9 13 10 16 217 8 19 -- 11 12 15 30 9 10 6 14 8 8 218 9 19 31 16 10 6 25 15 12 5 16 8 3 219 7 12 37 9 13 7 24 12 11 10 11 10 8 ------------------------------------------------------------------------------ ALL 8 14 34 14 15 11 27 12 10 10 17 9 12 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 213 214 215 216 217 218 219 STATION ------------------------------------------------------------------------------ 3SNA 1054.554 1085.327 1065.547 1071.905 1052.327 1053.088 1.036 1.052 1.036 1.046 1.002 0.969 BIPD 1056.811 1089.025 1077.130 1071.085 1066.819 1058.217 0.993 0.968 0.965 2.059 1.126 1.026 BORG 1052.904 1084.915 1068.164 1059.321 1062.470 1050.651 0.893 0.895 0.955 0.892 0.878 0.895 BRUG 1055.252 1088.708 1074.236 1072.438 1061.903 1065.876 1056.112 0.907 0.911 0.897 0.922 0.900 0.904 0.917 CSIR 1060.464 390153.016 1066.503 1065.185 1059.972 0.978 112907.328 0.922 0.946 0.996 DLFT -50.479 -17.564 -32.469 -35.098 -42.945 -39.626 -48.683 0.889 0.882 0.858 0.876 0.874 0.869 0.877 GODZ 111.197 143.634 135.958 112.795 121.971 115.481 112.965 0.920 0.939 1.324 1.397 0.926 0.945 0.943 HERP 1058.570 1088.098 1074.971 1073.004 1060.755 1062.857 1057.601 1.008 0.952 0.954 1.043 1.015 1.044 0.979 IRKZ 109.507 137.176 122.972 120.417 112.118 114.907 106.450 0.924 0.900 0.874 0.863 0.894 0.876 0.869 KHAB 117.284 116.000 104.509 110.918 0.912 0.886 0.904 0.901 KR0G 39.835 69.737 56.417 52.742 46.176 47.600 37.982 0.832 0.840 0.818 0.814 0.825 0.839 0.841 LDS1 -893.370 -851.264 -873.721 -864.999 -884.833 -883.243 -892.115 1.347 1.304 1.284 1.614 1.512 1.563 1.609 LINR 1060.727 1099.564 1080.453 1061.523 1072.479 0.956 0.992 0.968 0.959 0.915 MDVZ 109.015 142.878 125.914 121.018 116.852 120.058 108.607 0.887 0.896 0.863 0.860 0.862 0.910 0.854 MTKA 105.402 132.240 121.520 116.298 108.637 116.527 108.548 0.944 0.968 0.917 0.917 0.941 0.868 0.872 OS0G 95.332 128.892 114.652 110.149 101.847 105.536 93.919 0.940 0.954 0.903 0.880 0.898 0.935 0.972 REYZ 129.009 158.992 143.278 143.909 134.307 169.001 0.903 0.919 0.878 0.879 0.895 4.780 SUNM -37.095 0.955 THU2 98.626 128.267 112.768 111.789 104.609 105.792 97.630 0.820 0.832 0.817 0.812 0.817 0.791 0.788 USNX 1047.687 1082.123 1062.958 1064.279 1059.929 1053.509 1052.525 0.954 0.969 0.979 0.978 0.930 0.916 0.935 VSLD 1052.173 1090.095 1069.919 1066.962 1057.254 1061.660 1052.904 0.939 1.699 0.941 0.963 0.944 0.947 0.963 WTZZ 111.288 142.948 131.561 126.416 113.532 122.857 111.098 0.929 0.904 0.939 0.898 1.254 0.939 0.935 YARR 111.979 144.102 129.352 127.195 117.297 121.580 116.687 0.926 0.930 0.928 0.922 0.893 0.877 0.939 ZIMZ 82.217 115.140 100.620 97.076 90.737 91.043 83.913 0.903 0.905 0.866 0.882 0.890 0.914 0.930 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 213 85152 2272 0.0015 214 84359 2452 0.0015 215 89450 2637 0.0016 216 86324 2285 0.0016 217 86693 2405 0.0016 218 82537 2471 0.0016 219 80664 2299 0.0015 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1021 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 21 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 6 PPPP PP 14 31 78 BIPD 5 PPP PP 4 16 80 BRUG 7 PPPPPPP 9 7 17 DLFT 7 PPPPPPP 2 3 4 GODZ 7 PPPPPPP -
