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 ------------------------------------------------------------------------------ 79 10 13 13 11 8 10 17 13 80 10 5 16 10 7 12 25 6 81 14 6 14 12 15 12 19 8 82 16 5 14 8 22 14 12 14 83 6 5 9 26 15 29 12 10 84 8 6 11 15 7 16 7 11 85 7 12 13 14 9 21 16 9 ------------------------------------------------------------------------------ ALL 11 8 13 15 13 18 16 10 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 079 080 081 082 083 084 085 STATION ------------------------------------------------------------------------------ BIPD 1038.928 1041.820 1011.721 1041.852 1022.867 1035.184 1.320 1.265 1.278 1.274 1.203 1.196 BORG 1027.016 1035.901 1005.020 1010.181 1035.747 1014.612 1027.006 1.450 1.231 1.130 1.210 1.194 1.399 1.105 CRAR -152.404 -166.000 -172.699 -149.705 -151.032 -149.518 0.716 0.707 0.729 0.727 0.734 0.739 CSIR 1037.120 1036.251 1014.150 1011.850 1043.975 1029.440 1032.825 1.074 1.160 1.270 1.269 1.203 1.190 1.173 DAVR 10.825 18.180 -2.601 -9.825 26.448 12.054 9.749 1.451 1.442 1.392 1.411 1.543 1.501 1.517 DLFT -67.592 -65.567 -94.306 -93.682 -64.124 -82.980 -72.960 1.075 1.121 1.117 1.132 1.120 1.073 1.063 GRAB 88.328 89.909 61.278 61.590 92.592 72.296 83.048 1.094 1.159 1.127 1.164 1.153 1.102 1.085 GODZ 92.160 93.515 70.771 69.011 91.932 76.902 96.413 1.155 1.210 1.198 1.181 1.108 1.107 1.087 GOPE 78.264 79.745 51.303 53.317 81.465 63.378 69.595 1.079 1.141 1.112 1.151 1.139 1.110 1.073 HERP 1031.837 1002.238 1012.014 1034.198 1022.146 1032.241 1.299 1.727 1.598 1.290 1.283 1.336 KR0G 22.117 21.540 -3.567 -3.055 21.278 7.319 14.504 1.001 1.037 1.040 1.031 1.063 1.001 0.982 LHAZ 42.642 41.416 20.926 26.772 47.339 30.521 35.028 1.107 1.179 1.150 1.170 1.233 1.088 1.158 MTBG -68.587 -65.670 -88.789 -95.156 -73.822 -80.811 -81.346 1.285 1.426 1.398 1.394 1.372 1.274 1.242 MTKA 72.455 80.229 57.578 58.959 79.628 72.152 80.513 1.075 1.106 1.080 1.176 1.217 1.172 5.313 NPLC 1036.006 1008.811 1011.319 1041.021 1019.809 1034.670 1.106 1.147 1.164 1.152 1.120 1.110 OS0G -62.210 -59.610 -87.335 -87.776 -62.096 -77.309 -67.185 1.053 1.141 1.098 1.105 1.104 1.056 1.612 REYZ 114.758 116.594 89.012 92.207 115.552 94.250 107.339 1.061 1.090 1.092 1.082 1.086 1.046 1.017 STR2 -34.135 -30.311 -44.528 1.452 1.473 1.388 SUNM -99.032 -98.928 -91.231 1.258 1.360 1.438 THU2 75.260 74.781 53.609 47.954 75.291 60.966 73.509 1.013 1.029 1.027 1.017 1.025 0.986 0.986 TSKA 68.975 69.870 49.056 49.483 69.186 61.713 65.856 1.093 1.105 1.099 1.183 1.211 1.148 1.186 USNX 1028.882 1032.683 1007.371 1004.638 1033.279 1.186 1.269 1.258 1.202 1.119 VSLD 1026.466 1024.377 991.683 994.084 1039.241 1009.393 1030.272 1.065 1.136 1.513 1.577 1.306 0.946 1.147 WTZZ 93.252 96.804 71.652 71.627 100.688 82.594 90.513 1.088 1.149 1.149 1.218 1.158 1.114 1.090 YARR 89.062 87.444 74.770 68.332 90.845 90.527 88.713 1.072 1.102 1.087 1.153 1.206 1.205 1.261 ZIMZ 63.491 69.099 37.984 42.784 68.715 49.288 58.957 1.082 1.149 1.122 1.179 1.144 1.105 1.081 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 079 98788 2439 0.0013 080 98900 2525 0.0014 081 106934 2536 0.0013 082 97710 2501 0.0014 083 99664 2556 0.0014 084 98672 2301 0.0014 085 88366 2291 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1054 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 25 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PP PPPP 7 3 70 BORG 7 PPPPPPP 4 8 29 CRAR 6 PPPPPP 37 21 37 DAVR 7 PPPPPPP 31 29 17 DLFT 7 PPPPPPP 2 4 3 GODZ 7 PPPPPPP -
