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 ------------------------------------------------------------------------------ 304 14 12 15 27 11 17 18 27 5 305 20 13 7 19 16 17 18 25 9 306 12 13 9 27 18 24 12 36 10 307 14 8 12 17 12 11 19 33 9 308 17 8 9 21 19 16 11 19 4 309 -- 8 15 29 16 10 10 19 8 310 -- 9 7 73 14 12 16 23 9 ------------------------------------------------------------------------------ ALL 15 10 11 35 15 16 15 27 8 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 304 305 306 307 308 309 310 STATION ------------------------------------------------------------------------------ BIPD 1154.351 1149.880 1.887 1.137 BORG 1049.523 1051.494 1066.580 1125.711 1148.638 1143.058 1141.144 0.978 1.029 1.016 1.764 1.125 1.072 1.005 CSIR 1096.736 1132.182 1163.275 1148.903 1138.748 1.262 1.086 1.098 1.108 1.089 DLFT -45.568 -46.332 -29.156 32.892 59.246 49.582 45.385 0.997 1.004 1.040 1.053 1.143 1.080 1.052 GRAB 105.481 104.340 123.932 182.211 211.245 201.027 196.518 1.028 1.056 1.084 1.106 1.166 1.139 1.088 GODZ 125.219 107.246 122.621 200.716 219.826 204.665 209.246 1.543 1.041 1.099 1.668 1.116 1.149 1.196 HERP 1067.036 1060.526 1071.219 1156.500 1149.027 2.788 4.116 3.871 3.425 3.455 IRKZ 100.645 98.199 126.168 178.386 198.681 202.798 190.518 0.991 0.982 1.030 1.083 1.188 1.138 1.084 KHAB 95.268 91.365 122.262 173.116 191.407 190.084 188.257 1.014 0.992 1.056 1.080 1.222 1.123 1.109 KR0G 38.332 38.069 57.331 115.275 138.910 129.787 131.331 0.942 0.935 0.958 0.998 1.076 1.024 1.021 METZ 92.510 97.085 111.867 172.360 198.255 184.394 187.047 0.975 1.010 1.041 1.050 1.154 1.077 1.048 MTKA 105.332 97.564 128.318 189.134 185.666 1.029 1.004 1.055 1.142 1.127 OS0G 96.852 95.008 112.057 172.625 199.147 189.158 186.282 0.977 0.988 1.014 1.048 1.129 1.069 1.035 REYZ 126.341 125.861 149.030 207.248 234.757 228.725 223.160 0.992 0.965 1.019 1.021 1.126 1.056 1.031 SUNM -42.684 -48.037 -10.091 52.382 68.651 50.944 40.661 1.263 1.136 1.191 1.215 1.399 1.387 1.364 THU2 95.096 179.886 198.168 188.849 192.139 1.087 1.413 1.060 1.043 1.001 TSKA 96.475 86.516 117.356 170.578 190.312 183.684 180.397 1.043 1.010 1.059 1.128 1.230 1.132 1.118 USNX 1053.737 1045.203 1060.326 1127.447 1151.629 1139.510 1144.402 1.080 1.037 1.038 1.033 1.118 1.131 1.214 VSLD 1053.997 1052.726 1069.829 1136.204 1151.189 1147.899 1143.917 1.050 1.086 1.090 1.867 1.186 1.098 1.110 WTZZ 112.408 115.047 127.513 197.291 221.199 210.599 205.280 1.035 1.065 1.069 1.132 1.174 1.138 1.097 YARR 113.072 111.039 142.155 191.081 216.010 208.161 201.541 1.003 1.044 1.105 1.143 1.197 1.172 1.132 ZIMZ 83.746 84.244 100.711 162.302 192.631 180.139 1.034 1.064 1.091 1.106 1.183 1.129 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 304 96905 2087 0.0013 305 93607 1956 0.0014 306 94772 1983 0.0013 307 68364 1612 0.0012 308 68980 1916 0.0012 309 94320 2206 0.0012 310 91976 2059 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1034 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 20 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 2 PP 38 4 124 BORG 4 PPPP 2 12 19 DLFT 7 PPPPPPP 3 3 6 GODZ 7 PPPPPPP -
