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: 101E107E108E109 113 115 122 ------------------------------------------------------------------------------ 107 15 10 17 14 21 10 20 108 6 10 13 16 14 9 12 109 12 11 22 15 29 10 12 110 14 13 20 29 24 23 14 111 11 8 13 29 16 15 10 112 13 7 10 22 14 20 23 113 11 11 12 17 23 25 16 ------------------------------------------------------------------------------ ALL 12 10 16 21 21 17 16 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 107 108 109 110 111 112 113 STATION ------------------------------------------------------------------------------ BIPD 1108.234 1103.832 1097.902 1142.743 1196.177 1224.866 1157.714 1.285 1.275 1.309 1.346 1.452 1.362 1.420 BORG 1103.039 1098.541 1092.996 1135.330 1191.680 1219.159 1150.797 1.218 1.180 1.211 1.243 1.349 1.261 1.333 CRAR -75.188 -77.453 -75.170 -39.245 18.551 27.992 -28.707 0.779 0.774 0.771 0.802 0.806 0.754 0.800 CSIR 1118.078 1110.674 1102.248 1142.018 1216.868 1219.072 1161.550 1.222 1.236 1.210 1.534 1.285 1.280 1.367 DAVR 97.398 87.087 89.999 123.785 197.326 145.263 1.483 1.620 1.449 1.456 1.456 1.476 DLFT 3.043 -2.915 -9.351 33.949 94.711 90.942 34.543 1.145 1.112 1.156 1.220 1.330 1.443 1.249 GRAB 161.851 154.081 146.583 190.708 247.753 274.966 210.614 1.173 1.171 1.187 1.238 1.341 1.245 1.297 GOPE 150.322 140.187 143.207 179.610 237.813 264.582 198.677 1.167 1.436 1.352 1.228 1.329 1.220 1.280 HERP 1101.618 1095.620 1136.590 1201.515 1217.318 1169.594 1.680 1.296 1.523 1.533 1.333 1.863 KR0G 91.759 84.117 82.773 122.883 175.496 204.911 141.954 1.082 1.084 1.074 1.158 1.262 1.120 1.145 LHAZ 118.693 107.138 112.305 145.169 1.240 1.227 1.244 1.229 MTBG 1.510 -1.700 75.296 125.219 68.710 1.418 1.348 1.608 1.532 1.509 MTKA 159.787 145.420 193.646 236.086 264.569 204.743 1.249 1.206 1.289 1.333 1.188 1.199 OS0G 8.677 1.719 -3.636 39.635 94.437 112.722 57.844 1.137 1.130 1.122 1.210 1.272 1.431 1.222 REUN 195.286 225.623 139.633 210.063 256.108 296.098 219.072 20.098 93.650 49.444 14.116 11.824 10.538 27.927 REYZ 175.262 176.628 176.221 220.246 274.014 305.069 237.530 1.101 1.110 1.132 1.188 1.311 1.149 1.156 SUNM -9.928 -3.465 29.187 66.509 96.390 46.614 1.542 1.503 1.575 1.499 1.395 1.432 THU2 149.423 140.859 139.702 180.767 229.951 262.449 198.404 1.048 1.077 1.093 1.151 1.235 1.117 1.076 TSKA 151.872 134.669 141.211 184.673 227.575 254.720 194.977 1.244 1.215 1.213 1.278 1.344 1.192 1.203 USNX 1107.359 1099.658 1096.441 1134.485 1155.929 1209.369 1155.586 1.210 1.277 1.264 1.315 1.437 1.329 1.275 VSLD 1102.525 1098.904 1091.345 1140.179 1197.422 1219.007 1160.655 1.247 1.221 1.279 1.313 1.436 1.304 1.468 WTZZ 165.488 157.735 150.657 190.160 261.376 280.872 220.380 1.290 1.254 1.281 1.340 1.453 1.370 1.477 YARR 170.179 163.615 169.281 192.615 256.343 267.608 224.613 1.213 1.282 1.742 1.250 1.209 1.178 1.246 ZIMZ 134.953 128.252 121.171 168.378 227.282 253.280 187.625 1.169 1.148 1.179 1.219 1.349 1.239 1.269 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 107 91016 2140 0.0014 108 94835 2082 0.0013 109 78910 2090 0.0013 110 89114 2098 0.0014 111 91146 2173 0.0014 112 79416 2079 0.0013 113 89002 2052 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1058 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 7 PPPPPPP 6 25 73 BORG 7 PPPPPPP 7 24 14 CRAR 7 PPPPPPP 17 32 42 DAVR 6 PPPPP P 31 27 40 DLFT 7 PPPPPPP 1 2 5 GOPE 7 PPPPPPP 1 1 5 GRAB 7 PPPPPPP 1 2 3 HERP 4 PPPP 35 49 119 KR0G 7 PPPPPPP 2 3 7 LHAZ 4 PPPP -
