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: 101 106 107 108 109E111E113E115E116E122 ------------------------------------------------------------------------------ 255 7 57 11 24 12 13 8 14 18 11 256 9 61 6 11 10 11 7 11 13 8 257 6 79 11 14 12 11 11 15 11 9 258 14 67 6 10 5 9 10 8 11 9 259 8 93 7 17 13 10 8 13 9 7 260 12 222 11 12 8 10 8 16 11 25 261 8 128 17 22 6 11 9 9 14 10 ------------------------------------------------------------------------------ ALL 9 115 10 16 10 11 9 13 13 13 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 255 256 257 258 259 260 261 STATION ------------------------------------------------------------------------------ BIPD 1051.778 1052.530 1050.862 1051.594 1.006 0.985 1.045 1.009 BORG 1044.250 1049.298 1045.782 1030.873 1045.988 1064.089 0.925 0.930 0.988 0.980 1.057 0.973 BRUG 1047.376 1051.687 1046.413 1033.290 1052.956 1067.066 1.041 0.930 0.957 1.001 0.989 0.989 CSIR 1050.791 1050.134 1048.316 1045.340 1059.599 1060.853 0.976 1.016 0.962 1.051 1.036 1.030 DLFT -56.977 -53.222 -56.410 -68.649 -32.515 0.950 0.920 0.958 1.000 0.978 GRAB 104.022 87.265 105.572 123.996 0.981 1.022 1.001 1.023 GODZ 103.925 112.341 104.379 96.528 106.671 126.472 1.029 1.041 1.022 1.021 1.850 1.007 HERP 1009.363 1068.258 3.462 1.997 IRKZ 99.880 98.363 97.960 92.364 102.509 118.765 0.975 0.939 0.932 0.953 0.946 0.955 KHAB 94.267 98.174 92.157 92.666 97.286 113.944 1.009 0.985 0.965 0.984 0.953 0.988 KR0G 33.966 36.391 31.583 24.163 40.666 59.188 0.904 0.872 0.892 0.936 0.913 0.916 LINR 1053.684 1050.847 1054.389 1054.181 1.020 0.975 0.943 1.001 MDVZ 102.136 104.239 103.593 90.396 107.506 124.310 0.969 0.907 0.929 0.960 0.946 0.980 METZ 84.348 91.730 88.894 76.766 94.159 115.994 0.932 0.926 0.945 0.969 0.947 0.982 MTKA 98.970 102.419 95.729 101.084 105.727 123.449 1.059 1.004 0.968 0.973 1.417 1.609 OS0G 89.147 92.077 90.039 78.527 93.701 113.139 0.931 0.915 0.937 0.980 0.950 0.970 REYZ 127.176 120.096 105.982 123.988 144.394 0.934 0.934 0.980 0.922 0.963 SUNM -51.741 -53.333 -50.526 -47.504 -40.330 -39.401 1.189 1.125 1.106 1.128 1.092 1.185 THU2 89.016 94.964 87.524 92.481 116.803 0.895 0.885 0.878 1.254 0.910 USNX 1039.169 1051.776 1042.262 1034.881 1048.231 1062.057 1.072 1.074 1.012 1.017 0.959 1.002 VSLD 1045.536 1050.458 1043.180 1032.101 1050.273 1063.956 0.971 0.957 1.001 1.030 1.015 1.006 WTZZ 102.713 106.741 107.623 91.106 112.223 133.631 0.962 0.947 0.980 1.013 1.004 1.034 YARR 108.571 110.234 114.782 118.488 1.023 1.055 1.025 1.048 ZIMZ 74.164 75.642 77.673 49.971 0.952 0.930 0.972 2.632 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 255 86802 2183 0.0014 256 93612 2440 0.0014 257 108894 2665 0.0013 258 96181 2190 0.0014 259 81977 2007 0.0014 260 88307 2295 0.0014 261 78073 1804 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1027 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 3 PPP 0 25 36 BRUG 7 PPPPPPP 7 8 13 DLFT 6 PPPP PP 2 3 11 GODZ 7 PPPPPPP -
