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-96: 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: 101 103 104 106 107 108 109 110 111 113 115 116 120E122E ------------------------------------------------------------------------------ 185 11 10 11 10 6 26 35 56 18 35 28 14 15 12 186 19 8 14 41 18 73 21 35 24 16 21 20 11 11 187 18 7 13 24 29 24 18 35 12 33 28 31 17 10 188 12 13 8 38 24 27 20 37 35 22 19 14 13 13 189 19 14 11 28 27 11 16 22 11 22 13 15 6 11 190 5 14 11 25 13 15 22 16 18 37 24 15 10 9 191 11 10 16 23 15 10 32 41 22 22 39 27 10 10 ------------------------------------------------------------------------------ ALL 15 11 12 28 20 33 24 37 21 28 26 20 12 11 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 185 186 187 188 189 190 191 STATION ------------------------------------------------------------------------------ 3SNA 1027.623 1009.783 1008.225 1018.100 1016.774 1010.738 1.010 0.953 0.955 0.970 1.684 1.032 BIPD 1028.009 1024.150 1010.857 1.813 0.927 0.964 BORG 1025.327 1013.724 1004.664 1020.188 1011.165 1017.768 1005.204 0.863 0.859 0.851 0.888 0.878 0.872 0.870 BRUG 1030.022 1017.531 1009.728 1024.417 1017.001 1021.319 1007.080 0.860 0.876 0.872 0.906 0.893 0.886 0.937 CSIR 1028.535 1020.194 1026.953 1021.752 1022.449 1016.524 0.896 0.915 0.923 0.913 0.920 0.959 DLFT -77.360 -86.000 -81.112 -92.074 0.844 0.845 0.820 0.834 GODZ 76.457 81.068 75.664 83.091 73.593 2.121 1.064 0.875 0.861 0.884 HERP 1031.700 1019.881 1010.972 1025.501 1018.004 1021.586 1012.272 0.894 0.879 0.868 0.879 0.917 0.889 0.934 IRKZ 55.453 0.847 KHAB 79.870 62.247 59.023 72.705 63.002 62.028 56.544 0.931 0.948 0.973 1.582 0.927 0.858 0.866 KR0G 20.642 3.754 -4.746 6.661 0.605 -3.974 0.900 0.876 0.830 2.806 1.716 0.782 LDS1 -912.540 -932.554 -922.183 -925.051 -915.661 -936.857 1.078 1.203 1.233 1.254 1.165 1.349 LINR 1031.489 1019.229 1019.959 1034.435 1027.223 1017.813 0.907 0.895 0.897 0.894 0.916 0.926 MDVZ 85.242 73.040 63.420 77.297 65.928 77.184 65.459 0.908 0.963 0.996 0.909 1.584 0.897 0.825 MTKA 80.773 66.223 67.435 63.317 66.285 59.486 0.955 0.974 0.885 0.943 0.883 0.889 NPLC 1027.833 1017.408 1009.654 1022.673 1014.773 1020.271 1011.109 0.871 0.878 0.871 1.384 0.879 0.875 0.909 OS0G 69.329 56.548 50.607 64.039 56.799 61.013 52.292 0.845 0.932 0.899 0.962 0.905 0.929 0.919 REUN 58.823 56.075 60.066 58.762 67.508 62.096 2.116 2.126 2.298 1.831 1.294 1.611 REYZ 100.629 92.066 86.882 99.621 0.982 0.815 0.869 1.498 SUNM -60.178 -70.647-61518.192 -62.339 -69.525 -65.407 -69.525 0.935 0.952 2450.748 0.906 0.966 1.173 1.081 THU2 74.139 59.150 53.816 63.412 59.188 63.503 52.292 0.970 0.770 0.942 0.869 0.787 0.773 0.791 USNX 1027.682 1011.889 1007.289 1015.859 1011.794 1018.646 1009.944 0.923 0.933 0.912 0.902 0.901 0.904 0.925 VSLD 1026.422 1015.107 1006.547 1021.282 1013.299 1019.431 1007.626 0.860 0.884 0.882 0.898 0.886 0.859 0.892 YARR 72.965 72.381 74.346 77.639 78.619 70.834 0.906 0.922 0.963 0.901 0.882 0.885 ZIMZ 61.401 50.216 62.193 46.890 51.848 42.293 0.875 1.014 1.545 0.870 0.857 0.877 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 185 47496 1959 0.0016 186 52639 2427 0.0015 187 40100 1859 0.0015 188 51921 2093 0.0015 189 63947 2319 0.0014 190 45254 1962 0.0014 191 88096 2767 0.0015 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1017 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ 3SNA 4 P PPP 15 12 25 BIPD 3 PPP 4 5 71 BORG 7 PPPPPPP 2 6 24 BRUG 6 PPPPPP 3 5 13 DLFT 4 PPPP 1 4 3 GODZ 5 PPPPP -
