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: 101 106 107 108 109 111 113 115 116 122 ------------------------------------------------------------------------------ 290 12 10 11 15 13 13 18 12 13 8 291 10 10 8 12 9 11 6 14 8 8 292 16 9 11 13 9 12 10 19 9 12 293 19 11 8 16 16 20 6 12 19 11 294 13 12 8 16 20 17 9 9 13 8 295 20 12 7 14 16 30 15 14 21 10 296 13 17 6 12 24 28 13 13 18 8 ------------------------------------------------------------------------------ ALL 15 12 9 14 16 20 12 14 15 9 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 290 291 292 293 294 295 296 STATION ------------------------------------------------------------------------------ BIPD 1060.689 1057.184 1060.179 1037.724 1031.373 1043.653 1045.841 1.102 1.105 1.072 1.044 1.011 1.014 1.048 BORG 1053.340 1048.234 1053.960 1032.321 1026.113 1042.287 1041.049 0.993 0.997 0.995 0.983 0.927 1.007 0.951 CSIR 1054.068 1056.040 1057.302 1035.911 1028.532 1045.248 1.025 1.032 1.036 1.019 1.052 1.051 DLFT -42.963 -48.531 -44.629 -62.719 -66.986 -62.971 -59.176 0.999 1.006 0.996 0.991 0.952 0.963 0.974 GRAB 109.006 104.016 104.974 89.167 86.977 91.255 93.787 1.028 1.043 1.045 1.035 0.970 0.988 0.986 HERP 1053.384 1030.656 1066.278 1047.774 1045.177 1051.385 3.269 5.259 4.312 3.116 3.490 4.324 IRKZ 105.360 102.733 107.612 78.080 82.924 90.352 92.357 0.972 0.984 1.021 1.036 0.982 0.952 0.951 KHAB 97.099 92.689 101.204 70.909 76.199 80.752 85.328 1.013 1.004 1.042 1.059 1.025 0.981 0.961 KR0G 43.651 37.653 44.413 21.092 19.082 23.998 28.131 0.958 0.935 0.953 0.947 0.903 0.895 0.914 LINR 1062.332 1062.985 1067.891 1.032 1.073 3.965 MDVZ 112.227 109.571 0.983 4.809 METZ 99.209 91.416 94.717 78.807 70.755 76.976 82.495 0.984 0.976 1.010 1.003 0.935 0.930 0.958 MTKA 104.472 103.135 107.689 77.720 80.751 85.051 93.501 1.013 1.018 1.059 1.082 1.063 1.010 0.990 OS0G 97.801 93.065 94.504 78.321 74.960 79.803 82.908 0.968 0.978 0.983 0.972 0.937 0.936 0.942 REYZ 121.339 128.430 108.413 104.815 113.782 116.619 0.958 0.996 0.963 0.945 0.939 0.964 SUNM -37.973 -37.962 -57.945 -75.847 -66.297 -57.332 1.158 1.209 1.242 1.239 1.175 1.120 THU2 99.929 90.585 97.633 71.251 74.865 80.218 85.789 0.934 0.914 0.936 0.964 0.910 0.890 0.913 USNX 1050.714 1037.733 1052.579 1032.147 1022.756 1036.427 1039.639 0.993 0.980 0.974 1.061 1.103 1.042 1.093 VSLD 1055.324 1050.051 1055.760 1035.246 1027.743 1040.837 1042.984 1.064 1.061 1.020 1.033 0.996 1.002 1.020 WTZZ 115.544 115.025 116.461 98.465 94.308 97.839 102.553 1.007 1.068 1.047 1.050 0.980 0.985 1.000 YARR 112.831 120.658 116.098 93.548 88.311 92.252 100.721 1.050 1.054 1.069 1.063 1.067 1.177 1.011 ZIMZ 84.506 85.973 85.312 67.551 65.715 69.046 71.832 1.021 1.070 1.030 1.014 0.978 0.997 0.999 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 290 88704 1906 0.0012 291 94491 2088 0.0012 292 89383 2027 0.0012 293 89448 1937 0.0013 294 95042 1976 0.0013 295 91555 2145 0.0015 296 88690 1995 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1032 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 19 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ DLFT 7 PPPPPPP 2 1 3 GRAB 7 PPPPPPP 1 1 3 HERP 4 P PPP -
