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: 101 107 108 109 110 111 113 115 116 122 ------------------------------------------------------------------------------ 16 11 8 11 13 -- 11 20 19 23 21 17 9 13 8 8 -- 8 14 16 24 18 18 15 12 15 9 -- 8 11 10 22 12 19 23 10 11 12 -- 8 11 9 18 10 20 17 8 15 11 -- 15 9 9 10 10 21 14 11 18 12 -- 20 18 15 13 7 22 16 14 17 9 -- 15 31 11 15 14 ------------------------------------------------------------------------------ ALL 16 11 14 11 -- 13 18 13 19 14 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 016 017 018 019 020 021 022 STATION ------------------------------------------------------------------------------ BIPD 1160.425 1091.385 1061.831 1089.271 1166.161 1180.690 1.835 1.375 1.125 1.217 1.250 2.928 BRUG 1165.982 1092.572 1058.723 1087.574 1169.230 1175.179 1.398 1.244 1.079 1.599 1.770 1.953 CRAR -4.137 -81.683 -2.792 0.922 0.826 0.708 CSIR 1103.758 1068.909 1110.375 1163.780 1.216 1.093 1.111 1.242 DAVR 173.740 111.147 66.874 113.981 186.675 188.899 1.104 1.117 1.101 1.337 1.169 1.198 DLFT 67.236 14.585 -18.630 61.657 85.345 1.036 1.101 1.062 1.108 1.012 GRAB 220.729 218.461 173.123 116.006 136.140 214.409 238.313 1.012 1.053 1.164 1.090 1.127 1.169 1.087 GOPE 212.582 210.174 161.011 104.353 126.382 207.077 229.104 0.997 1.053 1.155 1.065 1.114 1.159 1.063 IRKZ 213.398 0.998 KHAB 208.305 218.176 151.201 100.774 129.358 1.038 1.033 1.065 1.049 1.084 KR0G 156.840 76.476 48.091 69.576 147.391 162.877 1.014 1.234 1.020 1.081 1.111 1.045 LHAZ 174.031 178.227 129.980 75.023 91.675 172.638 3.085 1.146 1.111 1.088 1.134 1.519 METZ 209.037 211.161 160.177 105.121 130.232 209.696 229.072 0.996 1.041 1.116 1.053 1.073 1.116 1.045 MTBG 52.398 46.797 -9.567 -57.582 -33.986 34.101 60.712 1.129 1.125 1.245 1.212 1.236 1.237 1.171 MTKA 209.520 220.205 159.524 106.270 131.938 225.302 218.731 1.070 1.059 1.122 1.070 1.149 1.112 1.149 OS0G 72.007 18.738 -37.189 -11.819 69.735 91.373 1.000 1.071 0.998 1.035 1.077 0.988 REUN 215.644 208.546 153.823 104.411 3.182 3.788 4.510 4.437 REYZ 244.208 250.156 190.786 133.696 165.659 248.625 265.054 0.994 1.044 1.078 1.003 1.047 1.078 0.985 THU2 205.789 216.112 148.879 97.485 129.113 217.936 226.471 0.939 0.964 1.004 0.950 0.990 1.015 0.962 TSKA 220.577 210.407 1.359 1.140 VSLD 1085.999 1065.911 1089.497 1.556 1.801 3.376 WTZZ 233.292 227.949 181.050 117.023 147.126 223.649 245.755 1.022 1.063 1.172 1.193 1.136 1.176 1.061 YARR 173.505 126.122 148.869 235.682 1.014 1.058 1.155 1.143 ZIMZ 197.576 148.013 90.731 116.802 192.377 217.081 1.064 1.163 1.072 1.130 1.179 1.053 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 016 60220 1657 0.0014 017 69765 1867 0.0012 018 94142 2133 0.0012 019 96078 2157 0.0013 020 104692 2330 0.0012 021 92577 2046 0.0011 022 48937 1323 0.0014 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1045 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 24 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PPPPPP 5 20 67 BRUG 6 PPPPPP 6 12 36 CRAR 3 P P P 57 181 74 DAVR 6 PPPPPP 104 38 70 DLFT 5 PP PPP 1 2 5 GOPE 7 PPPPPPP 1 0 9 GRAB 7 PPPPPPP 2 4 10 IRKZ 1 P -
