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: 101E107E108E109 110 111 113 115 116 122 ------------------------------------------------------------------------------ 318 8 10 -- 19 -- 26 15 21 -- 6 319 6 11 -- 9 -- 20 21 13 -- 7 320 13 10 -- 36 -- 25 17 33 -- 14 321 13 12 -- 47 -- 22 13 18 -- 9 322 11 8 -- 16 -- 25 31 25 158 8 323 15 10 -- 20 -- 54 15 37 65 10 324 12 12 -- 34 -- 53 40 27 108 7 ------------------------------------------------------------------------------ ALL 11 10 -- 29 -- 35 23 26 117 9 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ GLONASS/GPS TIME OFFSET: ------------------------------------------------------------------------------ OFFSET (NS) RMS ERROR (NS) DAY : 318 319 320 321 322 323 324 STATION ------------------------------------------------------------------------------ BIPD 1126.045 1140.479 1118.543 1066.328 1081.012 1116.216 1.193 1.201 1.263 1.230 1.195 1.187 BORG 1120.689 1137.209 1116.518 1061.488 1074.876 1110.451 1196.490 1.100 1.097 1.151 1.142 1.124 1.102 1.068 CSIR 1139.170 1119.765 1068.207 1075.659 1122.379 1197.906 1.155 1.203 1.154 1.104 1.144 1.048 DLFT 22.773 39.885 17.721 -38.608 -19.172 14.349 104.725 1.146 1.124 1.168 1.151 1.087 1.135 1.080 GRAB 176.825 190.898 169.202 114.194 135.342 170.429 261.638 1.184 1.176 1.184 1.214 1.233 1.251 1.196 GODZ 153.584 207.442 177.236 113.838 139.926 166.687 1.720 1.215 1.243 1.237 2.780 1.246 IRKZ 167.284 187.400 173.244 114.299 129.138 168.885 260.335 1.153 1.135 1.146 1.126 1.148 1.205 1.136 KHAB 156.098 183.458 167.257 106.122 121.359 164.664 1.193 1.151 1.193 1.124 1.159 1.193 KR0G 107.617 127.548 107.613 50.559 69.100 104.903 1.077 1.059 1.097 1.066 1.118 1.099 LINR 1111.620 1146.928 1061.402 1083.240 1130.430 1211.128 1.229 1.173 1.113 1.009 1.198 1.123 MDVZ 175.983 191.501 173.365 105.862 171.137 263.919 1.154 1.106 1.154 3.804 1.113 1.101 METZ 162.253 179.856 159.019 98.071 122.945 166.178 252.946 1.123 1.108 1.136 1.104 1.173 1.208 1.123 MTKA 160.694 181.767 172.071 109.569 122.258 171.871 254.902 1.237 1.235 1.230 1.157 1.089 1.174 1.103 OS0G 164.690 180.014 198.348 99.603 119.984 158.906 247.786 1.128 1.108 2.226 1.388 1.092 1.093 1.048 REUN 104.674 142.557 4.038 3.048 REYZ 184.707 139.242 146.610 184.595 283.462 1.522 1.117 1.137 1.153 1.111 SUNM 3.987 42.042 35.620 1.557 1.484 1.371 THU2 161.862 185.857 163.776 103.177 122.171 160.105 250.882 1.076 1.067 1.103 1.045 1.037 1.019 0.993 TSKA 154.151 175.844 166.694 104.119 117.192 165.191 249.879 1.221 1.219 1.212 1.159 1.134 1.230 1.162 USNX 1105.319 1143.848 1115.880 1056.701 1.232 1.187 1.203 1.195 VSLD 1122.275 1142.923 1116.372 1062.595 1078.306 1117.044 1199.065 1.200 1.333 1.153 1.166 1.183 1.161 1.058 WTZZ 183.196 197.858 181.809 121.018 143.262 175.881 269.869 1.180 1.174 1.227 1.209 1.235 1.231 1.205 YARR 171.116 197.548 185.835 119.056 132.639 1.265 1.170 1.180 1.132 1.165 ZIMZ 156.324 170.285 151.410 92.511 110.026 144.963 238.992 1.193 1.182 1.224 1.208 1.237 1.223 1.185 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ STATISTICS FOR 1 DAY SOLUTIONS: ------------------------------------------------------------------------------ DAY OBSERVATIONS PARAMETERS RMS (M) ------------------------------------------------------------------------------ 318 95790 2096 0.0013 319 97800 2109 0.0013 320 92855 2116 0.0014 321 90754 2057 0.0014 322 87958 1933 0.0013 323 91135 2041 0.0014 324 72760 1605 0.0012 ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ COORDINATE COMPARISON FOR 1 DAY SOLUTIONS: GPS WEEK 1036 ------------------------------------------------------------------------------ TOTAL NUMBER OF STATIONS: 24 ------------------------------------------------------------------------------ WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------ BIPD 6 PPPPPP 7 20 39 BORG 7 PPPPPPP 6 14 11 DLFT 7 PPPPPPP 1 3 3 GODZ 6 PPPPPP -
