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 109E111E113E115E122 ------------------------------------------------------------------------------ 72 8 7 12 17 8 10 13 9 73 7 13 14 14 11 8 12 11 74 6 6 13 17 15 15 16 22 75 7 11 10 28 19 6 13 11 76 10 11 7 15 9 13 15 10 77 6 14 8 18 10 7 15 12 78 6 9 10 13 13 10 23 10 ------------------------------------------------------------------------------ ALL 7 10 11 18 13 10 16 13 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 072 073 074 075 076 077 078 STATION ------------------------------------------------------------------------------ BIPD 1037.255 1044.097 1032.407 1018.425 1017.088 999.034 1011.501 1.210 1.220 1.261 1.294 1.227 1.224 1.175 BORG 1034.757 1038.291 1028.151 1011.935 1013.370 991.717 1004.123 1.197 1.315 1.209 1.188 1.503 1.346 1.139 BRUG 1042.809 1.393 CRAR -134.728 -130.932 -149.665 -151.383 -164.664 0.697 0.692 0.700 0.708 0.723 CSIR 1045.428 1047.363 1036.432 1029.218 1021.007 1011.628 1022.700 1.179 1.258 1.241 1.217 1.197 1.167 1.123 DAVR -4.820 -6.466 1.635 1.508 DLFT -65.609 -57.643 -70.704 -85.256 -88.129 -104.093 -101.313 1.059 1.082 1.116 1.104 1.088 1.067 1.068 GRAB 87.431 97.041 84.509 68.582 67.556 47.921 58.633 1.096 1.112 1.151 1.130 1.135 1.099 1.109 GODZ 103.454 104.863 89.393 81.662 72.550 56.330 70.570 1.154 1.171 1.154 1.096 1.128 1.105 1.127 GOPE 76.656 86.230 73.216 60.577 57.899 37.161 46.065 1.090 1.093 1.130 1.120 1.116 1.092 1.086 HERP 1038.117 1038.787 1004.608 998.322 1003.333 1.368 1.854 1.672 1.158 1.148 KR0G 22.923 31.106 13.050 4.173 0.063 -12.693 -8.505 0.993 1.019 1.021 1.002 1.023 1.024 1.029 LHAZ 40.087 58.309 24.032 13.678 1.110 1.151 1.221 1.164 MTBG -56.184 -55.498 -64.328 -83.851 -94.784 -98.505 -98.204 1.411 1.382 1.420 1.384 1.299 1.242 1.290 MTKA 89.294 94.296 70.834 74.102 50.450 55.731 55.489 1.091 1.086 1.136 1.147 1.358 1.165 1.188 NPLC 1037.773 1049.159 1032.959 1019.465 1018.114 1002.037 1010.816 1.124 1.353 1.142 1.157 1.145 1.140 1.093 OS0G -61.055 -53.237 -66.903 -82.596 -85.503 -98.378 -93.561 1.030 1.075 1.084 1.084 1.064 1.045 1.046 REYZ 116.310 125.702 112.498 93.626 89.977 72.998 86.274 1.057 1.060 1.056 1.040 1.069 1.034 1.054 STR2 -19.685 -14.776 -28.171 -31.746 -48.578 -39.801 -52.047 1.413 1.352 1.377 1.459 1.574 1.509 1.515 SUNM -72.661 -68.332 -81.080 1.326 1.250 1.273 THU2 82.482 87.695 70.847 59.693 53.537 42.708 46.494 1.007 0.998 0.999 0.983 0.999 1.003 1.007 TSKA 82.767 84.111 61.631 64.264 56.179 46.953 45.165 1.099 1.105 1.146 1.155 1.199 1.191 1.183 USNX 1040.851 1039.104 1027.086 1019.371 1009.245 994.659 1008.144 1.229 1.264 1.210 1.181 1.222 1.162 1.155 VSLD 1027.164 1034.470 1029.336 1006.954 1009.600 987.257 999.428 1.131 1.228 1.105 1.325 1.364 1.221 1.542 WTZZ 95.766 104.734 92.138 78.525 81.667 59.083 67.419 1.103 1.135 1.135 1.143 1.155 1.119 1.106 YARR 99.370 106.273 91.857 91.939 70.572 75.314 1.049 1.076 1.120 1.164 1.208 1.194 ZIMZ 63.947 76.450 63.914 48.311 47.003 24.383 38.207 1.084 1.120 1.149 1.146 1.142 1.087 1.097 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 072 103168 2488 0.0013 073 102373 2463 0.0012 074 100663 2316 0.0013 075 94597 2259 0.0012 076 86215 2268 0.0012 077 99539 2474 0.0013 078 94759 2388 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1053 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 26 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 7 PPPPPPP 6 12 41 BORG 7 PPPPPPP 5 5 26 BRUG 1 P -
