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: 101E103E104E106E107E108E109 110 111 113 116 117E120E122E ------------------------------------------------------------------------------ 157 23 13 16 23 34 37 46 -- 53 47 29 16 29 7 158 14 13 9 12 19 66 30 -- 53 56 38 15 20 8 159 15 16 22 17 26 48 25 46 47 66 35 11 24 8 160 17 14 21 25 14 20 36 37 38 30 40 15 20 11 161 7 20 11 29 18 31 19 37 30 24 62 23 12 9 162 9 9 10 41 13 22 39 48 30 34 38 14 20 8 163 10 12 18 29 16 27 36 77 59 38 54 22 15 12 ------------------------------------------------------------------------------ ALL 15 14 16 26 21 39 34 51 45 44 43 17 21 9 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 157 158 159 160 161 162 163 STATION ------------------------------------------------------------------------------ BIPD 1062.196 1060.468 1066.901 1.427 .954 2.459 BORG 1062.908 1070.017 1061.505 1061.138 1055.028 1063.400 1058.370 .874 .878 .825 .864 .867 .891 .861 BRUG 1066.565 1074.374 1065.589 1064.187 1056.454 1067.537 1063.440 .921 .890 .837 .876 .925 .930 .887 CSIR 1077.244 1073.186 1074.612 1066.558 1063.780 1065.861 1069.068 .942 .959 .931 .948 .910 .934 .923 DLFT -36.634 -28.182 -37.560 -40.147 -45.522 -34.667 -39.441 .866 .850 .802 .833 .828 .867 .924 GODZ 122.556 139.164 123.470 121.429 116.353 131.694 121.604 3.200 1.553 1.289 .888 1.004 1.798 .972 HERP 1067.231 1072.720 1067.690 1066.361 1061.070 1070.972 1062.621 .981 .949 .888 .933 .934 .894 .885 KR0G 56.174 61.048 51.245 47.208 47.605 58.923 45.856 .957 .881 .876 .903 .871 .916 .912 LDS1 -873.988 -866.135 -877.641 -875.212 -884.434 -872.666 -876.670 1.101 1.084 1.114 1.086 1.052 1.105 1.527 LINR 1069.423 1080.390 1074.887 1058.437 1067.790 1068.681 .934 .930 .916 .921 .887 .887 MDVZ 122.669 127.785 .959 1.228 MTKA 116.096 118.892 116.336 106.185 107.641 110.323 .971 1.115 .924 .982 .851 .927 NPLC 1064.564 1073.064 1064.125 1061.510 1055.541 1073.569 1059.629 .901 .899 .861 .900 .880 1.215 .905 OS0G 101.077 109.973 98.324 93.447 94.371 105.377 97.257 1.118 .960 .940 .895 .910 .931 1.006 REUN 119.967 114.456 124.971 108.995 120.931 99.104 135.199 2.130 1.558 1.580 1.624 1.876 1.751 2.650 REYZ 142.932 132.313 .953 .912 STRR 96.213 110.218 102.990 95.357 83.981 98.132 .993 .945 .985 .983 1.137 .965 SUNM -37.020 -18.224 -25.226 -34.754 -45.175 -31.553 -28.817 1.049 1.085 1.021 1.019 1.046 .971 .961 THU2 121.912 107.710 103.277 106.989 104.097 1.408 .807 .786 .910 .813 USNX 1057.425 1070.846 1060.268 1060.198 1049.628 1060.449 1058.369 .927 .923 .908 .908 .929 .928 .930 VSLD 1071.488 1080.378 1071.984 1066.072 1054.727 1066.019 1062.058 1.099 1.198 1.021 .954 .873 .892 .902 WTZG -683.493 999300.237 .984 1.043 WTZZ 123.695 129.689 122.463 119.745 115.981 129.441 118.061 1.137 1.045 .993 1.042 .898 .991 .967 YARR 130.489 132.639 125.957 114.606 110.803 120.836 129.510 .985 .947 .985 .965 1.060 .971 1.015 ZIMZ 108.299 93.759 90.845 89.756 97.467 89.923 1.499 .831 1.021 .991 1.009 .887 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 157 50687 1760 .0015 158 65201 2196 .0015 159 66538 2071 .0014 160 64914 2307 .0014 161 69381 2249 .0014 162 56739 2203 .0014 163 56414 1500 .0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1013 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 22 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 2 PP 9 14 1 BORG 7 PPPPPPP 2 4 18 BRUG 7 PPPPPPP 2 7 6 DLFT 7 PPPPPPP 2 1 6 GODZ 7 PPPPPPP -
