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: 101 103 104 106 107 108 109 110 111 113 116 117E120E122E ------------------------------------------------------------------------------ 164 11 12 17 10 21 37 20 72 50 30 54 20 10 9 165 15 12 22 22 18 63 33 33 16 51 22 9 14 11 166 14 11 20 12 15 81 40 40 17 34 44 13 12 15 167 8 29 24 17 20 131 9 42 14 26 40 19 13 14 168 10 14 28 10 19 55 20 37 28 26 28 20 13 11 169 6 11 18 6 12 261 51 83 18 55 53 33 11 17 170 13 13 24 30 13 115 25 56 31 47 71 22 9 21 ------------------------------------------------------------------------------ ALL 11 16 22 17 17 127 31 55 28 40 47 20 12 14 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 164 165 166 167 168 169 170 STATION ------------------------------------------------------------------------------ BIPD 1061.605 1070.964 1080.631 1083.260 1076.608 1067.496 1.098 1.631 0.968 1.022 1.004 0.963 BORG 1055.125 1051.479 1057.482 1071.497 1078.798 1080.911 1062.241 0.868 0.894 0.901 1.071 0.923 1.127 0.857 BRUG 1058.827 1053.075 1061.447 1076.669 1078.702 1078.060 1065.807 0.880 0.890 0.874 0.895 0.945 0.964 0.883 CSIR 1060.889 1064.542 1058.959 1079.991 1082.519 1083.511 1068.447 0.927 1.017 0.914 0.961 1.011 1.053 0.937 DLFT -42.485 -48.435 -43.886 -30.380 -29.894 -34.000 -37.668 0.871 0.947 0.917 0.882 0.924 0.930 0.900 GODZ 115.267 110.496 122.246 132.983 136.763 134.431 114.185 0.984 1.505 0.953 2.497 1.123 1.124 1.177 HERP 1058.057 1055.742 1078.694 1076.063 1073.395 1063.558 0.924 0.946 0.887 0.994 1.229 0.959 KHAB 101.231 111.295 125.627 111.707 106.865 0.858 0.969 1.104 1.119 0.961 KR0G 41.686 41.717 38.604 57.168 62.356 58.203 44.769 3.131 0.909 2.211 0.802 0.924 1.003 0.868 LDS1 -880.954 -889.093 -883.124 -875.371 -881.255 -885.178 -879.226 1.874 1.200 1.167 1.099 1.082 1.160 1.097 LINR 1060.163 1067.907 1059.041 1071.183 1114.969 1077.466 0.906 0.898 0.623 0.911 1.785 1.080 MTKA 92.841 98.023 106.908 125.638 119.596 112.823 0.967 0.955 0.885 1.026 1.127 1.041 NPLC 1056.826 1051.803 1060.552 1075.401 1064.226 1078.928 1063.962 0.885 0.920 0.905 0.885 1.326 0.986 0.886 OS0G 92.848 90.710 84.436 107.033 112.783 103.141 91.851 0.879 0.987 2.724 1.013 0.929 1.046 0.986 REUN 104.985 2.999 REYZ 127.603 133.988 148.228 147.826 144.958 129.284 0.992 1.062 0.972 1.064 1.067 0.948 SUNM -43.176 -34.543 -43.043 -32.017 -21.895 -32.862 0.934 1.011 0.990 1.020 1.049 0.938 THU2 95.200 96.362 102.520 111.076 117.247 116.588 103.302 0.923 0.875 1.011 0.879 0.939 0.978 0.787 USNX 1052.635 1048.525 1056.999 1062.584 1064.384 1073.616 1059.185 0.924 0.912 0.908 0.953 0.976 1.095 0.929 VSLD 1056.675 1051.127 1058.987 1069.787 1076.299 1074.961 1063.083 0.890 0.892 0.881 0.730 0.960 0.971 0.876 WTZZ 117.011 111.138 121.411 136.883 143.885 126.540 114.939 0.892 0.904 0.950 0.922 1.062 1.070 1.027 YARR 112.498 124.781 111.566 124.038 138.340 135.531 118.290 0.955 0.941 1.077 0.942 1.016 1.094 0.973 ZIMZ 86.542 89.594 91.402 98.370 114.151 100.165 92.501 0.963 1.166 1.333 1.430 1.004 1.003 0.875 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 164 44677 1532 0.0012 165 51078 1700 0.0013 166 42220 1918 0.0014 167 64962 2116 0.0014 168 71842 2532 0.0014 169 61590 2396 0.0013 170 72064 2302 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1014 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 21 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PPPPPP 4 11 37 BORG 7 PPPPPPP 4 11 27 BRUG 7 PPPPPPP 3 6 12 DLFT 7 PPPPPPP 2 1 7 GODZ 7 PPPPPPP -
