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: 101 107 108 109 110 111 113 115 116 122 ------------------------------------------------------------------------------ 30 7 5 11 9 -- 8 10 9 7 12 31 8 8 8 8 -- 12 11 6 7 9 32 4 9 10 5 -- 9 9 9 -- 20 33 11 8 13 16 -- 8 7 11 -- 28 34 8 9 18 8 -- 11 7 10 -- 14 35 13 4 21 8 -- 10 10 13 -- 11 36 12 7 18 12 -- 12 12 10 -- 19 ------------------------------------------------------------------------------ ALL 10 7 15 10 -- 10 10 10 7 17 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 030 031 032 033 034 035 036 STATION ------------------------------------------------------------------------------ BIPD 1200.681 1223.093 1200.085 1.117 1.085 1.162 BORG 1196.320 1216.680 1193.459 1205.758 1220.245 1161.654 1086.222 1.045 1.029 1.068 1.160 1.155 1.311 1.152 BRUG 1225.880 1217.191 1204.706 1223.303 1132.175 1103.441 2.321 1.909 1.439 1.341 1.546 1.863 CRAR 51.242 -36.880 -90.327 0.697 0.732 0.709 CSIR 1236.433 1200.391 1229.834 1142.519 1086.903 1.166 1.355 1.172 1.239 1.160 DAVR 209.041 205.106 234.605 139.763 91.725 1.182 1.167 1.110 1.310 1.229 DLFT 95.629 114.650 87.606 102.833 124.650 61.376 -9.277 1.038 1.044 1.124 1.072 1.120 1.205 1.102 GRAB 252.922 269.859 244.947 263.753 280.256 216.225 148.839 1.093 1.064 1.156 1.175 1.198 1.241 1.190 GOPE 243.785 261.376 234.933 251.533 271.766 205.415 139.575 1.085 1.077 1.147 1.165 1.187 1.237 1.165 KR0G 180.729 201.955 175.756 197.503 213.244 146.205 80.675 1.068 1.050 1.100 1.125 1.144 1.183 1.119 LHAZ 221.891 235.766 201.016 217.912 240.249 1.127 1.186 1.223 1.188 1.169 METZ 258.275 232.496 252.301 274.253 209.611 141.839 1.322 1.099 1.117 1.146 1.235 1.136 MTBG 95.240 80.652 107.773 129.802 70.880 -4.311 1.203 1.305 1.262 1.316 1.371 1.211 MTKA 252.617 266.132 238.661 250.494 275.040 202.879 137.290 1.150 1.135 1.172 1.131 1.163 1.232 1.180 NPLC 1195.452 1206.569 1227.153 1165.938 1092.157 1.468 1.154 1.136 1.245 1.137 OS0G 103.315 120.915 90.592 108.048 131.246 63.311 -4.106 1.020 1.022 1.093 1.049 1.086 1.162 1.071 REYZ 300.724 270.255 290.474 303.486 246.664 172.278 1.034 1.063 1.096 1.102 1.189 1.080 THU2 241.786 258.301 232.524 247.476 267.248 206.399 135.384 0.995 0.979 1.049 1.046 1.031 1.076 1.025 TSKA 244.406 259.984 232.871 240.454 265.442 192.993 128.562 1.142 1.163 1.155 1.140 1.165 1.253 1.176 USNX 1199.420 1207.796 1196.493 1197.873 1217.530 1155.280 1090.255 1.049 1.083 1.202 1.188 1.245 1.217 1.154 VSLD 1196.962 1216.452 1195.585 1204.972 1221.446 4163.438 1090.666 1.042 1.015 1.088 1.127 1.407 25.503 1.166 WTZZ 284.969 278.538 254.027 267.795 291.067 222.014 156.571 1.571 1.090 1.157 1.174 1.211 1.247 1.184 YARR 279.734 279.337 145.334 1.200 1.183 1.200 ZIMZ 232.477 248.318 273.495 196.708 129.495 1.084 1.082 3.324 1.258 1.191 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 030 79885 1884 0.0011 031 89937 2100 0.0011 032 79227 1823 0.0011 033 81725 1856 0.0011 034 93153 2102 0.0012 035 90417 2108 0.0011 036 96822 2169 0.0012 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1047 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 3 PPP 5 2 38 BORG 7 PPPPPPP 6 6 41 BRUG 6 PP PPPP 11 15 34 CRAR 3 PPP 10 2 19 DAVR 5 P PPPP 7 5 4 DLFT 7 PPPPPPP 2 3 4 GOPE 7 PPPPPPP 1 1 5 GRAB 7 PPPPPPP 3 1 4 KR0G 7 PPPPPPP 3 2 7 LHAZ 5 PPPPP -
