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: 101 107 108 109 111 113 115 122 ------------------------------------------------------------------------------ 93 19 28 6 16 40 17 10 20 94 12 17 -- 14 19 30 14 20 95 12 17 -- 12 16 21 8 18 96 24 37 -- 16 24 21 15 19 97 27 26 -- 9 20 20 9 25 98 22 37 19 46 25 35 10 8 99 12 20 17 22 13 22 22 17 ------------------------------------------------------------------------------ ALL 19 27 15 23 24 24 13 19 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 093 094 095 096 097 098 099 STATION ------------------------------------------------------------------------------ BIPD 1088.566 1121.293 1073.339 1046.544 1062.360 1064.986 1.322 1.347 1.400 1.505 1.239 1.219 BORG 1052.994 1082.911 1115.565 1064.764 1051.393 1059.487 1058.395 1.210 1.222 1.271 1.285 2.066 1.163 1.191 CRAR -123.045 -89.172 -72.304 -122.104 -119.501 -115.010 -114.060 0.719 0.774 0.867 0.769 0.806 0.709 0.734 CSIR 1061.374 1087.469 1123.592 1071.927 1042.774 1073.307 1.131 1.253 1.248 1.272 1.444 1.244 DAVR 41.293 73.790 103.261 45.507 35.102 54.655 50.712 1.522 1.507 1.501 1.478 1.478 1.454 1.522 DLFT -45.746 -20.921 12.547 -32.799 -58.471 -41.557 -39.167 1.067 1.148 1.208 1.189 1.341 1.074 1.108 GRAB 98.471 142.710 166.360 122.455 99.029 113.924 117.162 1.821 1.510 1.243 1.241 1.386 1.127 1.141 GOPE 94.384 123.427 156.426 111.230 87.112 101.743 104.263 1.096 1.188 1.237 1.234 1.371 1.115 1.130 HERP 1059.346 1082.522 1120.962 1068.270 1035.769 1059.412 1.181 1.217 1.297 1.452 1.751 1.620 KR0G 45.030 70.344 102.719 54.571 37.056 50.537 49.768 1.011 1.077 1.120 1.139 1.228 1.007 1.013 LHAZ 116.385 1.220 MTBG -49.696 -5.872 27.773 -42.619 -74.145 -40.126 -33.438 1.261 1.403 1.509 1.415 1.604 1.299 1.324 MTKA 103.967 122.724 155.561 112.246 101.315 107.191 1.151 1.227 1.211 1.215 1.258 1.143 NPLC 1059.214 1084.799 1117.570 1069.333 1045.692 1.153 1.200 1.251 1.276 1.420 OS0G -41.287 -17.185 16.311 -31.397 -53.377 -36.921 -34.023 1.044 1.122 1.188 1.167 1.265 1.057 1.073 REUN 101.991 148.697 164.600 7.746 14.448 17.905 REYZ 146.320 157.349 192.451 146.050 124.171 142.501 142.841 1.043 1.111 1.169 1.196 1.274 1.043 1.063 SUNM -51.873 -51.475 1.390 1.493 THU2 100.901 124.017 154.826 89.861 106.056 107.209 1.019 1.083 1.118 1.177 0.976 0.990 TSKA 94.757 113.509 147.411 113.583 97.093 113.313 1.114 1.280 1.226 1.715 1.147 2.075 USNX 1061.580 1084.723 1110.821 1066.160 1063.261 1.174 1.275 1.331 1.281 1.178 VSLD 1056.439 1075.527 1119.961 1068.066 1038.607 1060.006 1.197 1.522 1.372 1.335 1.488 1.214 WTZZ 107.938 144.434 167.860 124.908 100.406 114.650 124.847 1.161 1.289 1.339 1.361 1.561 1.222 1.223 YARR 124.146 141.337 152.412 112.128 122.727 129.699 128.535 1.210 1.225 1.218 1.206 1.217 1.154 1.184 ZIMZ 86.292 115.000 146.537 101.117 77.637 92.192 93.428 1.104 1.201 1.264 1.240 1.411 1.127 1.128 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 093 80030 1981 0.0013 094 79314 2043 0.0013 095 83228 2068 0.0014 096 72870 1889 0.0012 097 59760 2179 0.0016 098 89048 2261 0.0014 099 78229 2131 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1056 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 24 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PPPPPP 33 60 68 BORG 7 PPPPPPP 14 11 50 CRAR 7 PPPPPPP 64 29 38 DAVR 7 PPPPPPP 29 52 38 DLFT 7 PPPPPPP 1 2 4 GOPE 7 PPPPPPP 1 2 2 GRAB 7 PPPPPPP 1 2 5 HERP 5 PPPPP 31 49 63 KR0G 7 PPPPPPP 4 4 7 LHAZ 1 P -
