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 ------------------------------------------------------------------------------ 37 14 9 26 11 -- 17 12 15 -- 11 38 13 5 22 10 -- 24 9 13 -- 9 39 11 12 19 13 -- 14 14 19 -- 10 40 17 9 12 11 -- 14 8 13 -- 8 41 9 8 17 26 -- 13 11 7 89 10 42 9 14 26 14 -- 7 10 12 61 21 43 27 9 9 26 -- 14 12 15 104 0 ------------------------------------------------------------------------------ ALL 15 10 20 17 -- 15 11 14 87 12 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 037 038 039 040 041 042 043 STATION ------------------------------------------------------------------------------ BIPD 1078.069 1117.667 1073.975 1132.890 1127.530 1.203 1.390 1.255 1.514 1.208 BORG 1071.422 1118.757 1183.179 1082.544 1067.031 1129.364 1120.605 1.088 1.146 1.180 1.157 1.156 1.327 1.106 BRUG 1051.412 1116.589 1181.490 1125.707 1129.383 1.920 1.571 1.507 1.604 1.284 CRAR -95.624 -56.176 -15.584 -74.575 -71.312 0.741 0.753 0.777 0.725 0.754 CSIR 1094.125 1113.935 1172.102 1110.175 1084.434 1156.220 1146.117 1.139 1.713 1.158 2.074 1.260 3.386 1.187 DAVR 90.448 124.805 1.220 1.204 DLFT -28.591 19.086 70.645 -9.671 -20.152 36.881 27.808 1.101 1.096 1.166 1.097 1.159 1.149 1.122 GRAB 129.898 177.020 222.107 140.157 138.528 190.159 185.828 1.153 1.163 1.187 1.152 1.219 1.288 1.202 GOPE 115.905 163.886 211.609 119.685 129.168 180.486 174.753 1.140 1.130 1.191 1.549 1.211 1.276 1.203 HERP 1139.276 1125.711 1.447 1.166 KR0G 55.972 106.782 162.727 72.165 66.117 119.857 121.435 1.116 1.141 1.201 1.090 1.149 1.191 1.158 LHAZ 82.388 137.102 1.211 4.153 METZ 113.731 160.832 216.446 119.562 177.254 164.207 1.115 1.484 1.583 1.114 1.199 1.497 MTBG -18.233 28.824 65.127 -12.948 -24.170 44.249 33.786 1.288 1.246 1.317 1.257 1.268 1.399 1.331 MTKA 121.185 162.454 219.024 140.814 145.450 185.099 182.303 1.200 1.228 1.234 1.158 1.150 1.140 1.206 NPLC 1077.096 1116.641 1179.747 1087.890 1072.806 1130.689 1127.669 1.093 1.160 1.189 1.165 1.160 1.318 1.123 OS0G -23.781 22.625 76.773 8.116 -1.952 1.080 1.066 1.135 1.563 1.500 REYZ 151.325 204.897 250.697 166.026 173.126 215.906 208.922 1.058 1.094 1.151 1.097 1.179 1.216 1.137 SUNM -7.287 -15.611 4.289 8.707 1.358 1.284 1.292 1.257 THU2 115.966 162.534 214.974 132.317 133.563 171.714 174.040 1.023 1.054 1.100 1.065 1.122 1.138 1.098 TSKA 111.421 150.258 211.681 130.718 137.947 174.418 174.102 1.199 1.261 1.260 1.164 1.145 1.133 1.139 USNX 1070.846 1115.547 1193.107 1086.282 1080.316 1101.850 1118.149 1.082 1.215 1.218 1.372 1.270 1.365 1.140 VSLD 1075.009 1122.701 1186.756 1083.824 1069.935 1130.062 1125.324 1.102 1.131 1.185 1.172 1.169 1.296 1.131 WTZZ 140.233 186.063 237.453 150.733 146.890 199.173 195.329 1.239 1.161 1.335 1.164 1.215 1.297 1.247 YARR 137.188 171.597 234.255 152.036 156.611 190.339 199.075 1.274 1.281 1.288 1.132 1.174 1.170 1.228 ZIMZ 105.598 153.635 202.330 120.264 117.308 167.597 159.385 1.142 1.154 1.206 1.160 1.211 1.307 1.215 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 037 106868 2437 0.0013 038 98288 2494 0.0014 039 92637 2055 0.0013 040 84116 1982 0.0012 041 98939 2248 0.0013 042 84679 2290 0.0012 043 77361 2179 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1048 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 25 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 5 PP PPP 43 37 83 BORG 7 PPPPPPP 4 15 19 BRUG 5 PPP PP 23 49 36 CRAR 5 PPPPP 12 20 20 DAVR 2 PP 4 10 1 DLFT 7 PPPPPPP 1 3 4 GOPE 7 PPPPPPP 1 2 4 GRAB 7 PPPPPPP 1 2 4 HERP 2 PP 22 157 71 KR0G 7 PPPPPPP 2 4 8 LHAZ 2 PP -
