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 ------------------------------------------------------------------------------ 65 14 16 11 22 11 0 6 13 66 21 16 7 38 15 -- 5 14 67 10 15 15 30 15 27 11 8 68 20 21 10 17 14 30 8 25 69 12 13 5 25 22 21 8 12 70 14 6 7 15 10 41 11 18 71 14 9 8 9 12 35 11 14 ------------------------------------------------------------------------------ ALL 16 14 10 24 15 32 9 16 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 065 066 067 068 069 070 071 STATION ------------------------------------------------------------------------------ BIPD 1105.022 1100.587 1154.556 1151.721 1090.350 1031.949 1.281 1.398 1.315 1.295 1.293 1.218 BORG 1102.256 1102.738998901.077 1145.436 1069.973 1025.825 1033.213 1.189 1.635 13.863 1.186 1.504 1.159 1.295 BRUG 1091.638 1159.880 1149.496 1104.442 1044.015 1.870 1.290 1.179 1.372 2.032 CRAR -77.758 -22.540 -37.675 -108.796 -147.573 -136.599 0.732 0.719 0.738 0.728 0.712 0.737 CSIR 1090.289 1105.122 1165.951 1157.387 1089.629 1044.292 1047.519 1.242 1.438 1.264 1.240 1.216 1.123 1.144 DLFT 7.279 -2.514 -18.852 -75.971 -65.475 1.230 1.247 1.137 1.076 1.102 GRAB 161.554 159.520 206.169 202.338 139.024 78.358 88.960 1.266 1.285 1.218 1.137 1.169 1.094 1.125 GODZ 164.859 206.534 217.568 197.864 134.694 84.836 104.109 1.227 4.308 1.087 1.114 1.153 1.143 1.182 GOPE 151.390 146.221 195.143 190.799 128.259 70.576 77.212 1.238 1.268 1.210 1.121 1.162 1.087 1.108 HERP 1142.420 1094.110 1147.242 1144.932 1101.108 1031.110 2.155 1.474 2.053 1.196 1.399 1.486 KR0G 94.253 83.806 135.185 134.262 71.026 11.948 24.498 1.101 1.175 1.108 1.071 1.063 1.026 1.023 LHAZ 125.310 164.297 103.790 40.482 47.942 1.366 1.204 1.190 1.182 1.157 MTBG 10.314 5.668 52.954 45.777 -17.756 -69.153 -52.385 1.471 1.378 1.382 1.340 1.300 1.259 1.347 MTKA 152.223 199.134 203.251 127.731 82.167 86.209 1.341 1.225 1.241 1.166 1.179 1.167 NPLC 1102.842 1101.305 1154.461 1150.140 1087.627 1029.465 1038.095 1.186 1.280 1.225 1.189 1.185 1.150 1.146 OS0G 11.886 3.036 54.710 49.267 -14.110 -72.786 -59.392 1.194 1.222 1.185 1.104 1.100 1.054 1.053 REYZ 191.051 185.226 236.969 225.926 161.056 101.434 113.653 1.202 1.213 1.110 1.054 1.081 1.049 1.088 STR2 37.773 59.191 93.106 86.776 7.409 -25.854 -26.054 1.405 1.487 1.466 1.557 1.466 1.465 1.469 SUNM -79.078 -77.906 1.390 1.382 THU2 151.752 140.344 192.925 187.066 121.028 67.096 77.745 1.108 1.142 1.047 1.015 1.026 1.025 1.037 TSKA 140.906 190.043 193.381 123.838 71.425 76.626 1.178 1.239 1.218 1.176 1.188 1.184 USNX 1102.012 1092.176 1155.820 1133.944 1070.490 1019.522 1037.059 1.214 1.341 1.157 1.183 1.203 1.220 1.236 VSLD 1096.024 1092.839 1147.314 1083.710 1026.841 1027.474 0.990 1.163 1.183 1.123 1.234 1.324 WTZZ 171.315 163.993 215.075 209.199 148.210 84.289 93.673 1.275 1.266 1.216 1.145 1.188 1.108 1.110 YARR 151.881 212.736 217.495 215.351 138.641 89.790 99.042 1.129 1.655 1.214 1.253 1.214 1.214 1.150 ZIMZ 140.509 134.066 183.897 179.801 116.067 59.461 69.618 1.275 1.275 1.216 1.138 1.165 1.111 1.134 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 065 84568 2095 0.0013 066 77558 2052 0.0013 067 83377 2364 0.0013 068 87505 2475 0.0014 069 100314 2484 0.0013 070 104610 2580 0.0014 071 100800 2364 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1052 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 25 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PPPPPP 19 19 94 BORG 7 PPPPPPP 7 15 28 BRUG 5 PPPPP 7 13 23 CRAR 6 P PPPPP 19 20 35 DLFT 5 PP PPP 1 1 4 GODZ 7 PPPPPPP -
