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: 101 107 108 109 110 111 113 115 116 122E ------------------------------------------------------------------------------ 2 10 8 7 31 -- 10 26 30 32 8 3 11 10 10 16 -- 11 12 26 23 22 4 7 8 7 24 -- 15 15 18 21 14 5 10 8 14 19 -- 13 23 28 35 13 6 14 6 7 34 -- 16 42 20 64 12 7 8 11 8 10 -- 16 30 31 -- 15 8 7 9 18 16 -- 27 27 32 -- 9 ------------------------------------------------------------------------------ ALL 10 9 11 23 -- 16 27 27 38 14 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 002 003 004 005 006 007 008 STATION ------------------------------------------------------------------------------ BIPD 1233.464 1201.899 1232.387 1183.488 1.946 1.339 2.910 2.111 BRUG 1136.373 1204.134 1200.399 1230.659 1175.503 1229.252 2.112 1.450 1.263 1.748 2.504 1.782 CRAR -82.217 -43.424 19.122 14.363 31.097 -11.511 27.761 0.725 0.728 0.727 0.698 0.735 0.755 0.730 CSIR 960187.315 1214.834165819.836 15345.021 2.144134191.107 DLFT -1.563 35.156 106.318 98.747 122.242 65.182 106.925 1.088 1.112 1.147 1.101 1.063 1.055 1.038 GRAB 254.475 274.184 221.873 264.159 1.157 1.115 1.094 1.096 GOPE 183.208 251.716 241.668 266.859 210.733 254.859 1.160 1.189 1.153 1.108 1.086 1.095 IRKZ 188.206 254.640 255.297 284.381 210.375 253.372 1.124 1.156 1.143 1.096 1.182 1.125 KHAB 182.831 250.853 248.507 276.607 202.802 246.413 1.102 1.132 1.153 1.123 1.193 1.134 KR0G 79.888 121.432 190.930 183.243 216.844 148.355 195.951 1.108 1.106 1.124 1.099 1.095 1.074 1.033 LHAZ 214.221 295.190 240.850 173.334 212.643 1.211 2.588 1.238 1.241 1.204 METZ 135.405 179.284 246.969 241.659 268.983 1.089 1.146 1.314 1.644 1.098 MTBG 8.963 95.726 91.662 108.666 48.361 93.601 1.287 1.322 1.260 1.192 1.240 1.164 MTKA 188.073 252.647 243.935 278.327 203.136 248.546 1.151 1.163 1.227 1.162 1.216 1.181 NPLC 1218.810 1201.686 1124.790 1.690 2.895 4.758 OS0G -1.185 1.065 REUN 31.753 196.821 291.369 290.418 224.024 191.959 239.074 4.919 5.077 9.428 5.662 7.604 28.690 18.844 REYZ 180.634 220.967 283.115 279.253 312.721 243.982 293.893 1.097 1.104 1.114 1.090 1.070 1.031 1.051 SUNM 28.293 99.211 97.401 112.461 1.196 1.325 1.304 1.366 THU2 141.042 182.907 248.367 244.656 267.255 230.417 254.662 1.037 1.038 1.056 1.541 1.257 2.564 0.991 VSLD 1114.888 1129.104 1203.883 1233.205 1178.195 2.241 1.516 1.509 1.511 3.753 WTZZ 156.158 201.698 270.267 261.231 285.711 227.078 269.454 1.107 1.187 1.188 1.169 1.134 1.089 1.087 YARR 210.959 270.349 262.666 286.010 1.073 2.174 1.158 1.262 ZIMZ 129.471 167.712 240.938 231.221 255.515 197.794 244.020 1.138 1.164 1.200 1.161 1.116 1.082 1.096 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 002 56415 1417 0.0012 003 76715 2213 0.0013 004 71600 2109 0.0014 005 81277 2277 0.0013 006 91452 2104 0.0013 007 53221 1471 0.0012 008 82237 1981 0.0012 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1043 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 24 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 3 PP P 20 20 31 BRUG 6 PPPPPP 49 17 51 CRAR 7 PPPPPPP 24 39 37 DLFT 7 PPPPPPP 2 1 4 GOPE 6 PPPPPP 1 3 3 GRAB 4 PPPP 2 2 6 IRKZ 6 PPPPPP -
