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: 101E107E108E109 111 113 115 116 122 ------------------------------------------------------------------------------ 325 14 14 12 33 75 27 28 35 18 326 13 15 5 44 29 19 11 21 7 327 9 12 18 18 19 19 16 17 19 328 12 13 17 25 31 23 38 25 15 329 16 11 12 37 19 45 33 16 8 330 8 9 8 31 27 32 34 34 12 331 13 12 12 36 36 29 29 29 14 ------------------------------------------------------------------------------ ALL 12 12 13 33 38 29 28 26 14 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 325 326 327 328 329 330 331 STATION ------------------------------------------------------------------------------ BIPD 1092.092 1069.215 1122.922 1178.585 1083.343 1033.464 1.110 1.097 1.241 1.128 1.136 1.105 BORG 1180.742 1089.684 1065.611 1121.856 1174.011 1079.565 1029.054 0.982 1.039 1.010 1.143 1.015 1.032 1.436 CSIR 1170.964 1096.725 1080.876 1123.683 1179.224 1089.573 1042.681 1.062 1.153 1.145 1.234 1.085 1.090 1.041 DLFT 82.076 -15.915 -30.726 26.578 76.779 -18.497 -68.624 1.000 1.042 1.034 1.129 1.037 1.043 1.038 GRAB 231.172 132.228 122.890 179.275 230.339 135.961 83.387 1.040 1.076 1.073 1.164 1.080 1.073 1.076 GODZ 127.252 100.075 4.238 3.547 IRKZ 138.590 114.726 175.433 219.520 128.354 81.985 1.082 1.018 1.104 1.035 1.022 1.042 KHAB 134.948 110.000 169.664 210.134 121.047 76.196 1.135 1.038 1.137 1.049 1.049 1.057 KR0G 58.641 106.194 162.712 65.572 17.334 1.368 1.078 0.961 0.976 0.955 LINR 1153.716 1096.368 1073.524 1135.639 1179.287 1052.074 1.136 1.201 1.075 1.141 1.030 1.055 MDVZ 236.069 139.267 123.775 179.014 231.624 138.773 86.435 1.035 1.057 1.005 1.130 1.021 1.052 1.037 METZ 224.377 125.618 113.254 163.345 219.495 121.925 70.008 1.024 1.039 1.020 1.128 1.034 1.026 0.996 MTKA 209.508 125.040 163.151 204.052 115.371 69.993 1.121 1.212 1.147 1.077 1.066 1.091 OS0G 220.618 121.374 110.843 163.245 217.047 123.096 70.218 1.003 1.026 1.007 1.125 1.009 1.011 0.999 REUN 86.626 111.862 204.845 218.671 110.026 3.068 3.193 3.277 4.273 3.145 REYZ 254.584 165.985 156.516 206.015 257.877 166.035 117.681 1.168 1.020 0.992 1.119 1.016 1.026 1.028 SUNM 29.768 58.624 -40.331 -63.469 1.250 1.184 1.241 1.246 THU2 220.469 96.091 113.217 163.492 218.080 123.398 71.468 0.970 1.462 0.944 1.085 0.962 0.993 0.945 TSKA 204.007 132.386 101.021 166.086 206.975 97.812 73.704 1.135 1.156 1.068 1.145 1.081 1.246 1.080 USNX 1076.250 1066.329 1108.384 1175.618 1078.498 1026.229 1.187 1.104 1.214 1.051 1.070 1.000 VSLD 1181.209 1098.379 1069.663 1123.188 1175.786 1079.333 1031.911 1.023 1.221 1.043 1.129 1.017 1.020 1.018 WTZZ 243.384 140.342 130.323 189.152 237.789 145.880 91.582 1.060 1.083 1.068 1.176 1.094 1.097 1.076 YARR 128.070 191.223 232.037 128.600 101.858 1.101 1.144 1.055 1.117 1.115 ZIMZ 209.170 109.930 97.864 155.649 206.758 112.603 62.487 1.033 1.073 1.052 1.172 1.079 1.093 1.080 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 325 67222 1564 0.0012 326 85025 2066 0.0013 327 90337 2227 0.0013 328 106760 2293 0.0013 329 106803 2427 0.0013 330 103173 2244 0.0013 331 104952 2269 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1037 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PPPPPP 6 20 39 BORG 6 PPPPPP 4 5 25 DLFT 7 PPPPPPP 1 1 3 GODZ 2 PP -
