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 LHAZ 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: 101 107 108 109 111 113 115 116 122 ------------------------------------------------------------------------------ 23 11 8 20 11 13 8 18 13 17 24 7 8 12 9 11 17 27 13 8 25 9 4 4 13 7 13 19 21 7 26 9 14 6 16 8 8 11 18 6 27 9 11 9 7 11 12 11 17 7 28 9 6 11 4 16 6 12 12 13 29 13 9 10 10 7 12 13 11 10 ------------------------------------------------------------------------------ ALL 10 9 12 11 11 11 17 15 10 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 023 024 025 026 027 028 029 STATION ------------------------------------------------------------------------------ BIPD 1137.081737237.731 1085.771 681141.491 1120.352 2.167 3149.352 2.280 114336.686 1.111 BORG 1082.280 1096.928 1104.952 1118.413 1.616 1.101 1.061 0.979 BRUG 1155.048 1127.789 1093.664 1087.124 1146.260 1.257 1.146 2.117 1.593 1.806 CRAR -13.402 -62.323 -122.310 -106.184 0.701 0.688 0.778 0.667 CSIR 1115.859 1076.657 1083.466 1112.860 1116.346 1138.108 1.293 1.187 1.139 1.130 1.334 1.060 DAVR 180.545 104.651 1.122 1.183 DLFT 58.092 22.351 -28.514 -27.278 -2.515 6.161 19.321 0.989 1.023 1.213 1.050 1.085 1.055 1.028 GRAB 211.466 175.552 128.572 123.663 154.192 163.605 173.966 1.028 1.058 1.305 1.101 1.119 1.128 1.070 GOPE 204.102 167.210 118.140 114.775 144.850 153.025 163.396 1.027 1.036 1.273 1.073 1.102 1.090 1.052 KR0G 142.527 107.527 58.163 66.241 79.312 93.176 104.948 0.993 1.045 1.194 1.024 1.050 1.063 1.002 LHAZ 175.715 136.237 85.738 85.185 98.748 117.684 134.446 1.078 1.120 1.189 1.102 3.862 1.168 1.075 METZ 202.983 162.754 113.962 138.824 148.348 161.298 1.000 1.025 1.220 1.062 1.031 1.084 MTBG 43.648 3.804 -37.808 -36.066 -15.170 -0.240 20.235 1.147 1.148 1.436 1.272 1.308 1.254 1.157 MTKA 211.946 158.540 114.877 135.066 148.488 153.781 177.792 1.027 1.110 1.191 1.113 1.092 1.106 1.089 OS0G 64.963 26.471 -24.848 -21.679 1.888 11.004 25.605 0.965 0.994 1.158 1.012 1.045 1.040 0.994 REYZ 232.089 194.409 146.988 164.423 179.995 185.772 210.860 1.039 1.006 1.178 1.029 1.032 1.037 0.991 SUNM 21.386 -51.764 -35.764 1.277 1.452 1.185 THU2 201.808 159.742 111.071 126.304 136.648 152.690 169.327 0.923 0.992 1.092 0.955 0.957 0.984 0.963 TSKA 204.791 151.583 126.526 137.142 148.006 170.693 1.032 1.114 2.037 1.108 1.135 1.087 USNX 1107.319 1135.144 1.047 1.026 VSLD 1096.484 1105.980 1120.988 2.077 1.084 1.011 WTZZ 220.440 183.459 132.875 133.749 162.386 167.718 179.654 1.059 1.045 1.279 1.081 1.147 1.089 1.090 YARR 181.271 129.712 155.312 165.269 201.633 1.085 1.168 1.083 1.129 1.173 ZIMZ 190.659 153.326 106.892 102.941 132.147 139.560 153.309 1.023 1.050 1.312 1.081 1.127 1.114 1.067 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 023 88065 2083 0.0013 024 109137 2152 0.0012 025 65751 1740 0.0011 026 61291 1618 0.0012 027 93424 1969 0.0011 028 89911 2131 0.0011 029 96423 2022 0.0012 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1046 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 1 P -
