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 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 ------------------------------------------------------------------------------ 9 14 6 11 15 34 13 13 -- 15 10 6 6 9 10 17 6 9 -- 12 11 11 4 12 12 11 10 12 -- 11 12 7 8 12 11 20 8 9 -- 14 13 7 5 8 12 21 10 9 -- 14 14 19 4 8 5 13 13 16 34 11 15 9 4 12 12 14 9 11 35 23 ------------------------------------------------------------------------------ ALL 11 5 10 11 20 10 12 34 15 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 009 010 011 012 013 014 015 STATION ------------------------------------------------------------------------------ BIPD 1136.728 1157.526 1217.667 1164.499 1.727 1.372 2.776 2.220 BRUG 1170.991 1133.525 1128.571 1159.302 1212.832 1172.014 1178.989 1.301 1.434 1.466 1.285 1.292 1.208 2.170 CRAR -7.269 -59.895 -58.330 9.715 1.881 5.121 0.737 0.725 0.782 0.721 0.677 1.110 CSIR 1115.732 1194.503 1.401 1.742 DAVR 113.552 121.844 191.094 203.251 188.531 173.898 1.151 1.504 1.120 1.098 1.216 1.143 DLFT 76.336 19.194 22.062 72.978 111.733 78.534 78.392 1.111 1.095 1.249 1.165 1.117 1.005 1.015 GRAB 229.026 170.366 180.991 230.701 267.350 238.956 234.039 1.159 1.128 1.283 1.213 1.163 1.118 1.128 GOPE 220.342 162.871 171.154 220.926 257.571 230.907 220.863 1.143 1.124 1.267 1.187 1.143 1.074 1.035 IRKZ 219.453 166.995 171.767 229.272 260.408 228.701 229.813 1.161 1.086 1.199 1.160 1.097 1.134 1.080 KHAB 209.647 164.258 157.291 227.866 249.036 220.519 218.689 1.175 1.114 1.171 1.138 1.128 1.122 1.035 KR0G 160.131 112.203 113.981 164.372 195.852 165.355 161.347 1.121 1.102 1.217 1.142 1.087 1.086 1.083 LHAZ 182.206 129.293 108.738 186.195 222.768 192.930 192.158 1.184 1.101 1.872 1.227 1.164 1.178 1.156 METZ 160.227 164.559 216.831 251.842 221.394 222.503 1.089 1.238 1.145 1.112 1.067 1.086 MTBG 64.263 1.592 6.683 46.708 95.536 58.990 63.496 1.290 1.225 1.415 1.360 1.251 1.166 1.178 MTKA 209.762 164.367 164.874 226.486 246.471 224.252 221.215 1.197 1.151 1.208 1.158 1.165 1.132 1.053 NPLC 1108.501001061.394 2.020 5.196 OS0G 22.366 23.552 78.290 114.606 80.991 80.906 1.064 1.193 1.120 1.076 0.976 0.987 REUN 247.150 120.890 133.542 223.647 267.411 237.792 245.975 9.456 21.028 13.483 8.310 14.647 7.026 8.322 REYZ 199.528 200.153 262.354 286.328 257.423 255.542 1.094 1.193 1.099 1.070 1.036 1.042 THU2 211.784 150.335 174.410 226.699 249.989 221.100 219.829 1.080 1.669 2.331 1.030 1.007 0.947 0.954 WTZZ 239.845 180.283 187.514 238.905 276.084 242.355 240.836 1.159 1.160 1.298 1.203 1.166 1.101 1.114 YARR 231.628 179.206 173.452 252.936 259.308 244.159 1.149 1.076 1.247 1.185 1.242 1.198 ZIMZ 208.133 147.330 156.607 210.601 247.184 217.526 212.964 1.138 1.129 1.266 1.212 1.176 1.115 1.110 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 009 85415 1996 0.0012 010 101571 2340 0.0013 011 84091 2470 0.0014 012 104269 2361 0.0013 013 109468 2231 0.0012 014 88392 2182 0.0012 015 75941 1799 0.0013 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1044 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 23 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 3 PP P 16 55 40 BRUG 7 PPPPPPP 17 14 36 CRAR 6 PPPP PP 23 7 19 DAVR 6 PPPPPP 8 19 11 DLFT 7 PPPPPPP 2 1 4 GOPE 7 PPPPPPP 1 2 4 GRAB 7 PPPPPPP 2 1 2 IRKZ 7 PPPPPPP -
