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: IRKZ OS0G YARR ZIMZ. 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: 101E103E104E106E107E108E109 110 111 113 116 117 120 122 ------------------------------------------------------------------------------ 136 9 13 14 8 8 16 24 20 22 31 45 16 14 19 137 9 10 15 10 9 18 19 20 24 14 47 14 11 16 138 9 11 10 20 19 30 13 34 19 34 33 24 15 12 139 9 12 10 25 28 23 22 29 10 27 19 21 11 23 140 6 21 12 24 13 61 17 17 26 15 32 63 9 15 141 10 22 12 22 19 99 14 27 12 14 23 13 15 13 142 13 12 16 14 19 99 20 22 17 10 41 22 14 15 ------------------------------------------------------------------------------ ALL 9 15 13 19 17 75 19 25 19 23 36 30 13 17 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 136 137 138 139 140 141 142 STATION ------------------------------------------------------------------------------ BIPD 1057.014 1061.281 1056.157 1064.153 1066.361 1074.567 1070.716 .891 .893 .916 .980 .923 .947 .923 BORG 1051.079 1056.032 1052.682 1057.563 1059.960 1069.817 1067.502 .817 .842 .835 .858 .859 .838 .828 BRUG 1055.092 1060.939 1055.513 1062.113 1062.146 1074.364 1069.757 .821 .833 .839 .892 .922 .846 .839 CSIR 1052.890 1056.347 1056.616 1063.785 1060.038 1066.193 1066.765 2.036 .922 .875 .963 .867 .924 .871 DLFT -47.493 -43.581 -48.479 -42.474 -37.473 -29.147 -33.056 .816 .848 .802 .836 .876 .834 .819 GODZ 112.752 122.298 112.695 108.758 122.019 130.608 118.260 .864 .996 .994 1.609 1.030 1.048 1.199 HERP 1061.860 1055.288 1064.271 1065.389 1075.678 1070.700 .915 .835 .951 .935 1.006 .929 KR0G 39.028 44.071 45.476 48.514 52.655 58.966 55.442 .893 .953 .862 .807 .842 .790 .872 LDS1 -904.965 -886.085 -892.657 -883.749 -880.719 -870.626 -878.837 2.024 1.076 1.064 1.066 1.062 1.120 1.106 MDVZ 108.153 109.906 110.255 116.277 117.815 124.799 120.981 .887 .901 .997 .896 .897 .919 .890 MTKA 107.343 97.816 107.272 111.968 114.928 110.789 118.547 .849 .937 .854 .847 .935 .921 .893 NPLC 1054.388 1059.776 1059.653 1057.067 1062.842 .853 .855 1.084 1.317 .876 OS0G 88.439 94.014 92.188 94.688 99.416 107.626 .860 .885 .814 .885 .923 1.031 REUN 102.089 100.126 99.880 125.336 98.534 2.029 1.464 2.338 2.487 2.096 STRR 93.039 82.475 80.520 89.563 94.308 99.232 1.002 1.649 1.039 .896 .926 .917 SUNM -33.536 -44.134 -45.032 -44.795 -38.749 .992 1.029 .967 .947 .936 THU2 97.838 99.075 99.805 102.216 108.445 113.510 109.453 .774 .774 .819 .861 .877 .919 .817 TSKA 96.129 87.807 98.743 96.173 109.008 .947 .903 .949 1.001 .837 USNX 1050.282 1053.981 1051.775 1054.685 1059.675 1071.123 1065.381 .883 .891 .873 .900 .904 .921 .911 VSLD 1054.515 1060.383 1053.632 1060.035 1064.513 1070.695 1068.801 .842 .854 .842 .992 .901 .872 .848 WTZZ 116.696 112.025 121.341 121.496 135.011 122.814 .937 .938 .959 .912 1.059 1.016 YARR 114.926 113.784 114.817 119.480 115.681 120.943 .957 1.075 .877 .933 1.102 .928 ZIMZ 84.453 90.906 80.495 90.862 92.401 102.845 98.827 .940 .862 1.030 .883 .881 .863 .865 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 136 71437 2085 .0012 137 79178 2409 .0013 138 81156 2523 .0014 139 66439 2163 .0014 140 78169 2471 .0014 141 70868 2123 .0014 142 70389 1902 .0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1010 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 21 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 7 PPPPPPP 2 10 17 BORG 7 PPPPPPP 3 5 21 BRUG 7 PPPPPPP 3 4 11 DLFT 7 PPPPPPP 2 2 5 GODZ 7 PPPPPPP 7 9 30 HERP 5 PPPPP 10 30 43 KR0G 7 PPPPPPP 2 3 9 LDS1 7 PPPPPPP 2 5 13 MDVZ 7 PPPPPPP 2 4 12 MTKA 7 PPPPPPP 16 14 24 NPLC 4 PPPP 25 27 71 OS0G 6 PPPPPP -
