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 ------------------------------------------------------------------------------ 360 8 20 15 15 57 22 26 13 20 361 8 21 23 32 15 39 26 20 18 362 11 22 21 19 38 36 10 15 21 363 11 17 16 24 31 33 16 31 15 364 14 52 20 22 31 20 15 18 57 365 8 32 19 17 11 15 9 41 75 1 25 27 23 38 19 28 21 32 48 ------------------------------------------------------------------------------ ALL 13 29 20 25 33 29 19 26 42 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 360 361 362 363 364 365 001 STATION ------------------------------------------------------------------------------ BIPD 1208.997 1213.092 1207.163 1125.694 1.196 1.190 1.139 1.201 BORG 1205.557 1211.233 1200.107 1189.530 1167.052 1118.993 1.112 1.082 1.031 1.061 1.107 1.081 CRAR 29.216 17.697 13.793 15.331 -17.802 -69.259 -116.727 0.711 0.685 0.655 0.769 0.707 0.721 0.713 CSIR 1222.171 1200.141 1.135 1.096 DLFT 111.288 114.560 104.054 98.812 74.634 21.378 -18.538 1.121 1.099 1.049 1.061 1.013 1.035 1.103 GRAB 254.073 249.917 223.910 172.963 1.067 1.138 1.070 1.148 GODZ 267.305 1.137 IRKZ 257.065 129.327 1.121 1.119 KHAB 249.678 1.162 KR0G 203.440 201.956 189.126 181.793 158.509 103.776 66.847 1.124 1.094 1.024 1.069 1.036 1.113 1.204 METZ 255.510 261.572 241.185 241.150 216.279 159.893 125.837 1.125 1.162 1.452 1.090 1.069 1.112 1.160 MTKA 252.282 252.254 1.199 1.108 NPLC 1208.396 1213.792 1204.663 1198.867 1168.709 1123.881 1113.292 1.116 1.092 1.048 1.072 1.049 1.093 2.610 OS0G 99.608 102.542 78.295 25.653 -15.324 1.991 1.060 0.984 1.009 1.048 REUN 324.741 232.782 224.747 243.215 165.410 118.743 5.858 4.057 5.113 3.858 3.987 15.012 REYZ 307.173 296.596 288.934 278.375 252.065 191.438 157.159 1.254 1.044 0.992 1.039 1.037 1.038 1.172 THU2 255.107 258.429 244.801 235.232 213.626 160.295 119.411 1.033 0.993 0.947 0.991 1.011 1.045 1.097 TSKA 248.723 246.030 1.182 1.094 USNX 1196.852 1.108 VSLD 1207.403 1213.041 1203.419 1194.611 1155.347 1119.870 1.128 1.106 1.069 1.081 1.555 1.590 WTZZ 277.780 278.443 270.820 260.893 195.684 186.722 148.495 1.223 1.208 1.167 1.373 2.555 1.152 1.240 ZIMZ 233.375 246.844 234.764 230.596 203.189 152.105 116.275 1.752 1.157 1.407 1.119 1.091 1.132 1.220 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 360 75820 1987 0.0013 361 58225 1690 0.0012 362 54094 1535 0.0011 363 60271 1481 0.0011 364 60979 1434 0.0011 365 63760 1815 0.0013 001 57680 1520 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1042 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 21 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 4 PPP P 12 10 88 BORG 6 PPPPPP 6 8 5 CRAR 7 PPPPPPP 22 40 44 DLFT 7 PPPPPPP 1 2 6 GODZ 1 P -
