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 109E110E111E113E115E122 ------------------------------------------------------------------------------ 51 12 5 19 -- -- 26 23 18 17 52 7 7 15 191 -- 19 20 19 12 53 6 7 8 98 -- 9 24 10 19 54 7 7 10 70 99 14 23 14 29 55 7 9 9 67 -- 9 37 12 16 56 6 9 9 76 66 11 31 12 14 57 7 13 14 82 51 16 29 14 19 ------------------------------------------------------------------------------ ALL 8 8 13 107 75 16 27 14 19 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 051 052 053 054 055 056 057 STATION ------------------------------------------------------------------------------ BIPD 1134.408 1132.353 1137.049 1157.179 1252.839 1.244 1.672 1.230 1.243 1.254 BORG 1130.775 1119.063 1156.811 1274.436 1265.941 1250.694 1.176 1.443 1.161 1.119 1.040 1.122 BRUG 1134.536 1135.586 1140.068 1142.110 1278.928 1266.646 1254.341 1.348 1.183 1.567 1.356 1.401 1.915 1.155 CRAR -60.903 -61.440 -53.558 -1.552 95.988 0.757 0.754 0.736 0.779 0.705 CSIR 1136.134 1135.650 1131.366 1201.554 1288.770 1272.344 1254.487 1.234 1.178 1.160 1.183 1.095 1.084 1.138 DLFT 30.711 27.221 31.719 54.640 176.651 162.908 154.770 1.192 1.139 1.105 1.132 1.074 1.054 1.115 GRAB 188.050 179.811 180.375 207.447 329.598 318.003 310.837 1.215 1.209 1.236 1.292 1.201 1.161 1.239 GOPE 177.641 170.879 170.611 198.790 320.406 307.755 299.919 1.198 1.203 1.218 1.277 1.181 1.157 1.216 HERP 1142.314 1142.522 1260.504 1263.842 1.617 1.246 1.443 2.161 KR0G 120.206 113.954 109.169 150.000 273.225 1.096 1.109 1.137 1.260 1.340 LHAZ 154.868 142.010 194.427 263.909 1.249 1.464 1.382 1.142 MTBG 36.745 35.546 35.644 67.769 181.697 170.664 159.025 1.283 1.234 1.233 1.275 1.243 1.255 1.349 MTKA 192.046 186.889 180.188 237.145 331.013 310.093 303.281 1.217 1.264 1.260 1.384 1.186 1.089 1.611 NPLC 1136.931 1138.046 1138.629 1158.710 1277.913 1268.810 1.175 1.142 1.090 1.169 1.091 1.055 OS0G 36.389 31.042 36.215 63.079 181.375 166.939 159.558 1.147 1.131 1.064 1.126 1.034 1.027 1.063 REYZ 201.535 211.744 206.160 235.064 356.610 338.524 332.037 1.133 1.124 1.139 1.287 1.115 1.108 1.127 SUNM 14.721 9.071 16.916 53.675 162.240 143.710 134.901 1.326 1.491 1.490 1.420 1.360 1.486 1.368 THU2 178.559 169.459 165.461 207.989 321.488 307.020 299.282 1.051 1.042 1.067 1.222 1.081 1.063 1.069 TSKA 184.891 175.989 183.577 222.388 320.481 302.353 289.681 1.245 1.264 1.223 1.287 1.142 1.078 1.100 USNX 1134.223 1133.998 1128.434 1154.651 1264.229 1256.261 1.163 1.080 1.061 1.242 1.159 1.214 VSLD 1133.113 1135.462 1135.026 1155.880 1276.432 1266.483 1251.655 1.176 1.183 1.105 1.174 1.103 1.050 1.128 WTZZ 194.095 186.615 188.474 223.890 335.424 325.894 320.677 1.227 1.223 1.270 1.322 1.207 1.177 1.243 YARR 184.390 178.452 187.760 244.055 340.740 319.127 313.000 1.250 1.277 1.353 1.412 1.251 1.125 1.147 ZIMZ 162.332 157.714 156.999 185.427 308.550 296.618 291.541 1.216 1.224 1.253 1.309 1.189 1.186 1.253 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 051 92382 2207 0.0011 052 78803 2004 0.0012 053 87511 2054 0.0011 054 92851 2265 0.0011 055 85483 2036 0.0012 056 79178 1730 0.0012 057 79275 1865 0.0012 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1050 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 5 PPPP P 18 39 81 BORG 6 P PPPPP 9 9 14 BRUG 7 PPPPPPP 10 19 28 CRAR 5 PPPPP 28 15 30 DLFT 7 PPPPPPP 0 2 3 GOPE 7 PPPPPPP 1 2 3 GRAB 7 PPPPPPP 1 3 3 KR0G 5 PPPPP 2 2 9 LHAZ 4 PP P P -
