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 ------------------------------------------------------------------------------ 100 9 14 -- 27 27 38 5 12 101 17 15 16 19 22 29 7 25 102 9 11 10 17 16 22 8 5 103 8 24 15 10 21 14 8 6 104 5 11 13 15 21 18 14 5 105 9 14 18 15 12 14 13 7 106 9 11 11 15 38 19 11 20 ------------------------------------------------------------------------------ ALL 10 15 14 17 24 24 10 14 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 100 101 102 103 104 105 106 STATION ------------------------------------------------------------------------------ BIPD 1071.630 1087.239 1099.104 1154.395 1188.065 1088.688 1061.185 1.287 1.175 1.187 1.256 1.357 1.258 1.326 BORG 1066.654 1082.854 1096.392 1145.672 1179.293 1082.188 1059.866 1.209 1.099 1.136 1.182 1.294 1.197 2.239 CRAR -108.099 -93.164 -87.743 -42.116 -16.056 -102.894 -94.973 0.766 0.706 0.710 0.742 0.770 0.702 0.744 CSIR 1098.094 1146.163 1183.005 1078.978 1078.168 1.104 1.179 1.331 1.267 1.314 DAVR 59.172 70.888 74.628 158.887 70.314 78.116 1.543 1.403 1.375 1.487 1.359 1.434 DLFT -31.642 -17.096 -5.383 45.549 82.643 -19.467 -41.278 1.138 1.044 1.061 1.139 1.223 1.126 1.134 GRAB 120.568 137.972 148.483 202.734 236.022 135.915 112.584 1.176 1.095 1.111 1.146 1.250 1.155 1.172 GOPE 110.186 124.323 137.491 189.981 224.536 126.381 102.341 1.158 1.058 1.083 1.142 1.243 1.147 1.169 HERP 1071.473 1089.186 1094.897 1144.765 1182.011 1085.455 1053.642 1.292 1.344 1.203 1.231 1.291 1.228 1.363 KR0G 60.484 72.800 88.220 131.660 166.672 68.559 50.437 1.062 0.955 1.002 1.070 1.120 1.027 1.092 LHAZ 113.351 141.462 177.452 90.986 64.067 1.457 1.153 1.264 1.196 1.270 MTBG -36.176 -18.264 -2.713 35.456 63.863 -24.023 -36.096 1.382 1.211 1.258 1.369 1.471 1.361 1.369 MTKA 153.618 176.445 216.387 122.911 131.098 1.142 1.147 1.216 1.116 1.220 OS0G -29.013 -14.173 0.345 47.038 82.314 -15.978 -36.160 1.109 1.002 1.046 1.094 1.197 1.091 1.108 REUN 80.091 133.652 222.635 165.170 92.118 15.356 16.630 8.711 9.688 45.705 REYZ 143.393 161.663 177.372 225.974 262.317 158.294 141.552 1.095 0.999 1.027 1.081 1.131 1.057 1.082 SUNM -54.103 -28.402 -3.228 36.932 1.665 1.535 1.434 1.509 THU2 113.588 127.007 139.360 184.443 222.245 123.590 109.230 1.063 0.965 1.016 1.052 1.084 1.004 1.028 TSKA 120.566 142.400 166.282 205.111 114.183 122.813 1.135 1.139 1.139 1.204 1.113 1.222 USNX 1068.864 1088.422 1134.244 1177.980 1086.162 1071.971 1.234 1.216 1.285 1.274 1.211 1.216 VSLD 1070.287 -2254.574 1095.741 1146.825 1184.833 1080.894 1057.428 1.147 25.207 1.190 1.268 1.285 1.222 1.270 WTZZ 127.064 141.556 153.917 211.091 251.243 137.865 108.033 1.267 1.147 1.165 1.228 1.352 1.287 1.270 YARR 131.560 147.375 150.773 186.503 217.463 137.977 151.448 1.263 1.198 1.171 1.143 1.238 1.121 1.180 ZIMZ 98.444 113.774 125.355 176.660 214.893 112.991 92.288 1.164 1.077 1.098 1.139 1.246 1.149 1.176 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 100 75623 2078 0.0013 101 84245 2140 0.0014 102 90168 2365 0.0013 103 91674 2124 0.0012 104 90023 2298 0.0013 105 93277 2118 0.0013 106 93264 2197 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1057 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 7 PPPPPPP 8 27 48 BORG 7 PPPPPPP 3 5 18 CRAR 7 PPPPPPP 35 32 58 DAVR 6 PPP PPP 32 37 61 DLFT 7 PPPPPPP 2 1 2 GOPE 7 PPPPPPP 1 2 3 GRAB 7 PPPPPPP 1 2 3 HERP 6 PPPPPP 76 71 58 KR0G 7 PPPPPPP 3 2 3 LHAZ 5 PPPPP -
