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: 101 107 108 109 111 113 115 116 122E ------------------------------------------------------------------------------ 353 12 -- 15 20 15 21 20 38 12 354 11 17 7 17 17 21 14 19 8 355 8 15 14 15 25 12 9 24 9 356 10 10 22 12 20 11 12 32 8 357 10 11 27 18 16 15 24 70 9 358 9 13 25 16 15 10 17 18 13 359 5 22 16 18 19 17 20 35 12 ------------------------------------------------------------------------------ ALL 10 15 19 17 18 16 17 37 10 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 353 354 355 356 357 358 359 STATION ------------------------------------------------------------------------------ BIPD 1109.772 1113.161 1103.507 1136.804 1202.427 1163.591 1170.690 1.209 1.140 1.086 1.076 1.123 1.095 1.195 BORG 1105.888 1112.926 1098.988 1131.545 1197.952 1158.182 1168.088 1.100 1.047 1.011 0.995 1.065 0.999 1.099 CRAR -3.324 1.006 CSIR 1111.620 1116.825 1108.240 1149.964 1220.660 1154.464 1181.825 1.182 1.096 1.046 1.080 1.080 1.107 1.167 DLFT 6.950 12.368 -0.150 33.771 100.770 56.696 75.211 1.094 1.053 1.007 1.018 1.034 1.023 1.100 GRAB 160.398 163.544 150.928 185.870 252.337 1.171 1.088 1.043 1.056 1.119 GODZ 164.886 174.264 156.098 198.611 208.502 239.921 1.174 1.087 1.000 1.087 1.128 1.178 IRKZ 163.568 162.850 145.080 181.993 261.719 203.535 225.217 1.121 1.053 1.019 1.040 1.095 1.024 1.115 KHAB 154.223 156.342 138.962 174.287 254.715 196.686 213.158 1.126 1.095 1.039 1.133 1.082 1.058 1.105 KR0G 92.577 98.762 82.706 123.268 194.964 146.738 160.343 1.057 1.033 0.991 0.993 1.017 1.029 1.070 METZ 177.387 138.856 179.862 245.854 194.457 220.723 1.516 1.010 1.007 1.070 1.040 1.107 MTKA 155.639 143.601 176.565 1.177 1.080 1.089 OS0G 11.123 17.668 2.075 38.011 1.052 0.999 0.977 0.983 REUN 147.734 129.455 148.798 220.872 216.840 202.132 264.175 5.519 4.014 3.374 3.246 3.790 4.032 4.793 REYZ 191.943 172.165 215.188 292.360 233.154 258.793 1.435 0.977 1.011 1.035 1.016 1.090 SUNM -2.976 -11.919 -19.167 1.239 1.275 1.299 THU2 147.690 154.293 141.835 176.476 247.951 197.461 214.849 1.022 0.970 3.737 0.961 1.000 0.963 1.035 TSKA 149.821 154.852 136.710 171.342 190.210 210.686 1.201 1.092 1.065 1.096 1.085 1.151 USNX 1102.047 1112.359 1094.824 1134.986 1205.738 1153.666 1165.941 1.103 1.049 0.992 1.070 1.136 1.132 1.185 VSLD 1105.885 1112.969 1102.371 1132.444 1142.756 1168.873 1.161 1.038 1.006 1.114 1.566 1.133 WTZZ 169.542 176.519 161.425 201.934 266.664 221.760 238.533 1.185 1.178 1.116 1.164 1.122 1.099 1.211 YARR 174.210 1.147 ZIMZ 139.253 143.598 130.232 166.450 234.904 186.567 209.546 1.171 1.095 1.039 1.070 1.092 1.058 1.148 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 353 72476 1729 0.0013 354 98352 2195 0.0013 355 92857 2070 0.0013 356 93888 2181 0.0014 357 63655 1676 0.0014 358 69405 1766 0.0014 359 69119 1966 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1041 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 7 PPPPPPP 12 19 44 BORG 7 PPPPPPP 2 5 20 CRAR 1 P -
