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 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: 101 107 108 109 111 113 115 116 122E ------------------------------------------------------------------------------ 339 7 18 5 79 -- 20 22 45 8 340 12 5 7 34 -- 18 12 17 7 341 10 11 10 40 -- 40 30 39 6 342 4 9 8 44 -- 29 27 26 12 343 7 11 9 28 -- 33 21 23 16 344 9 12 11 43 55 38 25 31 7 345 9 13 11 37 58 32 24 20 10 ------------------------------------------------------------------------------ ALL 9 12 9 46 56 31 24 30 10 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 339 340 341 342 343 344 345 STATION ------------------------------------------------------------------------------ BIPD 1182.413 1173.664 1091.968 1108.187 1134.817 1112.622 1.161 1.121 1.125 1.138 1.168 1.138 BORG 1176.692 1170.899 1080.838 1087.046 1104.766 1130.804 1108.058 1.077 1.054 1.057 1.026 1.073 1.091 1.028 CSIR 1183.874 1164.900 1088.706 1099.211 1116.646 1135.308 1117.132 1.066 1.061 1.101 1.130 1.144 1.138 1.074 DLFT 77.130 73.661 -12.821 -11.390 4.390 37.577 11.998 1.116 1.080 1.061 1.066 1.011 1.062 1.034 GRAB 230.101 223.634 139.851 142.318 157.565 183.681 165.829 1.157 1.098 1.099 1.099 1.134 1.142 1.127 GODZ 232.854 212.112 147.708 142.044 159.269 178.966 166.126 1.208 1.870 2.103 1.182 1.151 1.136 1.085 IRKZ 228.553 208.473 136.391 148.919 149.084 173.625 166.235 1.111 1.105 1.093 1.066 1.076 1.101 1.122 KHAB 218.897 197.588 130.309 139.647 136.833 162.031 157.323 1.157 1.169 1.146 1.107 2.657 1.080 1.067 KR0G 157.953 149.295 70.512 74.329 83.455 109.839 93.197 1.031 1.025 0.991 1.001 1.018 1.050 1.063 MDVZ 233.056 222.457 144.396 146.470 156.082 190.187 1.126 1.096 1.059 1.054 1.075 2.996 METZ 223.848 207.649 123.778 129.837 142.602 159.550 1.943 1.127 1.448 1.055 1.065 1.697 MTKA 192.305 129.437 143.622 142.940 162.245 161.712 1.185 1.143 1.147 1.147 1.109 1.074 OS0G 217.267 212.234 129.612 131.468 147.228 171.534 154.408 1.075 1.079 1.029 1.052 1.071 1.106 1.103 REUN 237.795 138.154 154.554 158.209 154.121 4.049 3.503 3.644 4.442 7.317 REYZ 259.851 245.024 172.942 171.851 187.654 211.746 197.539 1.083 1.083 1.016 1.033 1.045 1.094 1.103 SUNM 60.455 59.501 -31.555 -7.725 -16.297 4.948 10.307 1.321 1.450 1.394 1.421 1.355 1.161 1.149 THU2 216.216 211.285 131.340 119.989 146.266 164.547 151.896 1.016 1.041 0.984 1.344 1.403 1.024 0.973 TSKA 214.602 196.748 124.374 137.229 139.489 158.720 154.617 1.168 1.195 1.158 1.141 1.154 1.109 1.065 USNX 1171.130 1079.173 1082.586 1096.711 1121.103 1103.651 1.116 1.079 1.173 1.104 1.122 1.043 VSLD 1162.941 1083.110 1089.054 1105.504 1133.329 1109.164 4.525 1.045 1.055 1.051 1.088 1.024 WTZZ 237.317 236.476 150.875 148.320 168.310 194.144 179.443 1.162 1.132 1.113 1.114 1.188 1.251 1.219 YARR 239.245 223.886 138.652 167.684 165.120 182.884 185.069 1.223 1.137 1.150 1.179 1.130 1.066 1.103 ZIMZ 209.030 203.241 118.550 119.124 138.494 161.755 145.810 1.152 1.109 1.099 1.098 1.133 1.153 1.154 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 339 89890 2195 0.0014 340 95299 2150 0.0014 341 99487 2210 0.0013 342 106506 2409 0.0013 343 101102 2171 0.0013 344 98207 2398 0.0013 345 96150 2094 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1039 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PP PPPP 11 29 35 BORG 7 PPPPPPP 2 7 8 DLFT 7 PPPPPPP 2 1 3 GODZ 7 PPPPPPP -
