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: 101E106 107E108E109 111 113 115 116 122 ------------------------------------------------------------------------------ 297 16 12 9 17 11 11 24 14 27 10 298 8 8 7 5 9 14 17 9 27 7 299 10 5 9 8 12 22 18 12 18 10 300 6 8 13 17 17 20 11 31 25 6 301 8 -- 7 13 18 11 13 13 32 11 302 13 -- 10 13 13 19 10 22 25 10 303 11 -- 9 13 12 22 17 17 24 6 ------------------------------------------------------------------------------ ALL 11 8 9 13 14 18 16 18 26 9 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 297 298 299 300 301 302 303 STATION ------------------------------------------------------------------------------ BIPD 1045.537 1057.754 1068.317 1.045 1.089 1.613 BORG 1039.405 1032.859 1050.989 1046.887 1067.456 1076.674 1057.555 0.960 1.027 1.001 1.011 1.035 1.003 0.986 CSIR 1068.637 1071.141 1050.657 1.034 1.126 1.068 DLFT -61.057 -63.896 -46.690 -54.012 -32.364 -24.301 -42.783 0.958 1.026 1.010 1.023 1.059 1.009 0.978 GRAB 93.339 91.226 107.667 101.742 119.788 124.400 110.834 1.009 1.056 1.031 1.073 1.073 1.037 1.008 HERP 1053.265 1053.074 1077.040 1050.435 1084.582 1085.597 1058.108 3.121 4.522 3.524 3.489 3.287 2.704 3.003 IRKZ 92.612 91.464 97.655 92.661 122.370 115.035 107.644 0.964 1.023 0.979 1.047 1.115 1.062 1.021 KHAB 82.471 86.676 92.163 87.528 115.796 113.533 103.191 0.964 1.029 0.998 1.080 1.107 1.090 1.049 KR0G 26.874 27.943 38.996 29.874 53.988 57.836 41.522 0.896 0.971 0.948 0.966 0.998 0.983 0.922 METZ 84.485 90.128 95.679 83.065 109.640 108.403 98.193 0.976 1.577 1.003 1.013 1.044 1.933 0.961 MTKA 93.745 100.332 98.367 97.373 121.883 118.964 107.070 0.994 1.060 1.001 1.101 1.149 1.116 1.122 OS0G 80.245 79.692 93.974 87.036 107.657 113.964 98.372 0.941 0.996 0.977 1.013 1.041 1.001 0.952 REYZ 114.018 115.543 125.046 109.233 140.285 153.557 133.307 0.926 0.991 0.953 1.025 1.010 0.998 0.941 SUNM -46.752 -58.977 -40.962 -49.661 -39.232 -41.580 -49.341 1.103 1.157 1.123 1.238 1.396 1.497 1.425 THU2 83.700 81.391 94.532 81.042 109.744 117.134 100.043 0.882 0.929 0.932 0.969 1.006 0.967 0.950 TSKA 87.391 117.967 102.460 98.565 1.102 1.970 1.547 1.123 USNX 1046.226 1037.294 1081.391 1054.107 0.973 1.022 1.153 1.064 VSLD 1041.145 1034.484 1051.205 1043.070 1067.389 1068.865 1063.097 1.013 1.093 1.041 1.204 1.085 1.319 1.299 WTZZ 99.673 96.512 115.144 110.745 130.253 133.298 117.071 1.011 1.065 1.025 1.068 1.093 1.054 1.014 YARR 103.971 98.262 108.271 112.981 128.088 123.888 111.921 1.016 1.086 1.017 1.070 1.135 1.091 1.038 ZIMZ 70.467 70.437 88.583 80.567 100.526 103.167 88.721 1.009 1.064 1.042 1.055 1.092 1.030 0.995 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 297 88395 1996 0.0014 298 81121 1783 0.0013 299 88192 1920 0.0013 300 90985 1982 0.0014 301 87660 2107 0.0014 302 84478 1906 0.0013 303 93090 1975 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1033 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 18 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ DLFT 7 PPPPPPP 2 2 3 GRAB 7 PPPPPPP 2 2 4 HERP 4 PPP P -
