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: 101E107E108E109 113 115 122 ------------------------------------------------------------------------------ 114 10 17 13 26 26 23 13 115 14 14 15 25 29 23 19 116 20 18 11 28 14 14 10 117 19 15 16 68 15 30 19 118 17 11 12 62 17 19 17 119 20 9 13 58 6 11 7 120 15 8 10 31 14 11 11 ------------------------------------------------------------------------------ ALL 17 14 13 46 19 20 14 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 114 115 116 117 118 119 120 STATION ------------------------------------------------------------------------------ BIPD 1116.038 1089.500 1120.913 1116.047 1117.436 1126.466 1.408 1.287 1.361 1.332 1.352 1.293 BORG 1111.682 1079.609 1116.118 1105.857 1110.633 1119.670 1116.069 1.232 1.247 1.223 1.427 1.253 1.200 1.282 CRAR -78.277 -87.932 -66.480 -62.627 -73.121 -63.869 -74.220 0.817 0.773 0.795 0.774 0.751 0.766 0.760 CSIR 1126.084 1089.774 1136.681 1123.543 1115.506 1126.682 1117.853 1.300 1.272 1.242 1.174 1.191 1.236 1.263 DAVR 102.485 73.211 113.936 103.619 81.168 102.281 87.898 1.479 1.521 1.653 1.509 1.482 1.480 1.520 DLFT -5.205 -36.162 -5.849 -8.480 -8.896 -0.559 -0.424 1.189 1.179 1.216 1.157 1.193 1.200 1.199 GRAB 166.983 138.343 169.175 164.580 167.409 173.893 173.454 1.221 1.191 1.201 1.189 1.201 1.193 1.248 GOPE 157.238 128.809 160.026 154.165 154.949 162.814 161.818 1.198 1.194 1.201 1.177 1.195 1.198 1.225 HERP 1112.589 1076.039 1109.460 1119.951 1.319 1.441 1.899 1.238 KR0G 101.635 71.211 103.238 97.105 94.635 106.407 105.450 1.117 1.097 1.115 1.097 1.153 1.135 1.410 MTBG 29.851 -13.286 20.979 6.726 19.426 20.780 1.445 1.551 1.432 1.346 1.468 1.528 MTKA 171.082 130.205 180.554 151.070 160.353 1.197 1.225 1.246 1.305 1.137 NPLC 1089.730 1.230 OS0G 17.642 -13.901 13.912 14.239 11.289 20.269 19.784 1.161 1.123 1.186 1.160 1.160 1.149 1.158 REUN 167.863 136.798 210.051 160.977 193.920 194.905 24.482 22.750 5.805 4.235 5.115 14.401 REYZ 196.601 168.257 192.927 195.218 189.808 197.451 194.320 1.118 1.118 1.162 1.127 1.201 1.128 1.135 SUNM 3.674 -18.646 -4.368 -4.530 -12.008 2.253 -4.854 1.474 1.545 1.595 1.565 1.563 1.448 1.398 THU2 159.091 128.964 157.164 157.932 152.588 166.185 159.394 1.075 1.078 1.132 1.082 1.104 1.110 1.074 TSKA 162.004 170.885 154.458 159.120 157.503 1.193 1.270 1.239 1.239 1.742 USNX 1106.375 1089.955 1096.717 1121.454 1109.733 1118.019 1115.203 1.224 1.241 1.302 1.252 1.324 1.273 1.325 VSLD 1114.215 1083.463 1118.083 1114.969 1113.396 1121.012 1118.308 1.312 1.247 1.354 1.280 1.292 1.312 1.343 WTZZ 161.570 140.106 167.528 168.676 175.186 183.866 177.251 1.306 1.310 1.295 1.285 1.300 1.333 1.371 YARR 159.190 148.582 185.114 180.529 157.998 173.004 163.048 1.214 1.213 1.335 1.228 1.196 1.158 1.165 ZIMZ 144.522 116.148 146.572 143.179 145.503 153.666 155.278 1.222 1.201 1.207 1.175 1.199 1.223 1.245 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 114 91749 2156 0.0013 115 79428 2158 0.0014 116 87056 1958 0.0013 117 81252 2029 0.0013 118 74341 2007 0.0014 119 84326 1996 0.0013 120 86316 2058 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1059 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PPPPPP 8 11 38 BORG 6 PPP PPP 2 3 20 CRAR 7 PPPPPPP 25 27 24 DAVR 7 PPPPPPP 19 22 35 DLFT 7 PPPPPPP 1 2 3 GOPE 7 PPPPPPP 1 2 4 GRAB 7 PPPPPPP 1 2 3 HERP 3 PP P 17 21 131 KR0G 7 PPPPPPP 2 2 4 MTBG 6 PPPP PP 1 2 4 MTKA 5 PPP P P 16 9 8 NPLC 1 P -
