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 LHAZ 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: 101 107 108 109 111 113 115 122 ------------------------------------------------------------------------------ 86 8 13 19 11 11 15 22 20 87 8 31 8 11 10 16 13 21 88 10 26 20 14 15 14 10 20 89 23 11 22 9 17 12 6 12 90 8 9 29 27 23 19 7 10 91 14 13 17 16 35 36 4 8 92 10 11 20 18 28 16 11 15 ------------------------------------------------------------------------------ ALL 13 18 20 16 22 20 12 16 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 086 087 088 089 090 091 092 STATION ------------------------------------------------------------------------------ BIPD 1043.728 1046.637 1038.901 1051.739 1055.150 1047.188 1061.238 1.198 1.229 1.330 1.225 1.275 1.218 1.218 BORG 1037.430 1042.376 1033.301 1046.463 1053.516 1041.419 1056.473 1.113 1.115 1.206 1.256 1.484 1.144 1.150 CRAR -148.754 -139.798 -143.261 -131.103 -124.342 -119.886 0.712 0.712 0.702 0.696 0.724 0.712 CSIR 1044.335 1047.583 1041.652 1054.466 1059.981 1052.154 1062.519 1.111 1.100 1.151 1.288 1.280 1.218 1.179 DAVR 15.846 23.031 18.959 33.368 40.102 40.812 46.860 1.442 1.400 1.365 1.334 1.385 1.447 1.557 DLFT -62.313 -56.522 -53.336 -50.009 -58.119 -43.145 1.073 1.072 1.109 1.124 1.101 1.066 GRAB 92.085 97.581 87.487 104.685 108.128 95.711 110.999 1.115 1.119 1.175 1.164 1.168 1.118 1.105 GODZ 98.902 1.167 GOPE 80.501 87.443 78.218 91.346 94.926 86.051 100.888 1.089 1.104 1.170 1.144 1.141 1.107 1.089 HERP 1035.188 1049.378 1032.839 1046.978 1060.042 1044.529 1058.715 1.252 1.945 1.308 1.130 1.007 1.441 1.141 KR0G 28.176 29.112 23.855 33.941 37.621 34.886 44.036 0.992 1.015 1.032 1.019 1.015 1.020 1.017 LHAZ 53.143 48.610 46.827 50.457 64.043 1.156 1.162 1.159 1.180 1.162 MTBG -69.037 -57.024 -81.031 -51.970 -50.548 -61.007 -40.751 1.259 1.312 1.471 1.350 1.355 1.316 1.258 MTKA 87.707 92.641 90.148 100.315 96.708 109.362 1.138 1.127 1.079 1.179 1.179 1.184 NPLC 1043.423 1047.372 1036.356 1050.240 1048.966 1061.789 1.107 1.110 1.188 1.133 1.146 1.158 OS0G -53.025 -65.278 -46.295 -52.642 -38.154 1.037 1.155 1.398 1.073 1.052 REYZ 115.820 117.903 112.932 124.888 126.647 127.499 144.874 1.040 1.047 1.091 1.057 1.035 1.056 1.030 THU2 82.272 84.095 82.154 87.823 91.397 90.809 99.831 0.988 1.021 1.025 1.008 0.977 0.992 1.005 TSKA 79.656 80.366 81.527 80.435 89.449 86.175 100.405 1.152 1.156 1.121 1.079 1.152 1.165 1.181 USNX 1035.219 1040.188 1037.591 1044.518 1042.088 1045.752 1052.283 1.168 1.209 1.242 1.241 1.136 1.192 1.209 VSLD 1043.301 1035.296 1044.363 1049.407 1041.010 1.114 1.235 1.060 1.228 0.906 WTZZ 99.712 106.881 96.621 103.649 117.840 102.691 110.583 1.125 1.122 1.191 1.254 1.295 1.223 1.187 YARR 93.160 95.932 94.379 105.210 109.767 114.653 120.904 1.165 1.105 1.072 1.104 1.201 1.152 1.162 ZIMZ 68.264 75.687 64.949 79.972 83.299 71.694 88.173 1.085 1.127 1.166 1.151 1.154 1.117 1.106 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 086 89696 2229 0.0013 087 80507 2068 0.0012 088 80640 2119 0.0014 089 73247 1880 0.0012 090 78223 1936 0.0013 091 71710 1918 0.0013 092 82223 1882 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1055 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 7 PPPPPPP 12 21 82 BORG 7 PPPPPPP 4 5 17 CRAR 5 PPP PP 25 58 33 DAVR 6 PPP PPP 40 18 27 DLFT 6 PP PPPP 2 3 2 GODZ 1 P -
