Abstract:
The technology for obtaining China Geodetic Coordinate System 2000(CGCS2000)production is related to the reducing problem of international terrestrial reference framework(ITRF), reference epoch, satellite ephemeris and velocity of station. Conversion model and parameter of different reference frames were introduced, data processing method for obtaining CGCS2000 production was discussed, effects of different ITRFs issued by IERS and satellite ephemerises issued by different international agencies on baseline were analyzed based on the observational data, and the difference of CGCS2000 production obtained by direct adjustment and framework conversion was explained. The results showed that precision of satellite ephemeris issued by IGS was higher than that issued by other agencies; effect of precise ephemeris of different reference frameworks on the baseline was less than 1.3 mm when the length of baseline was less than 4 000 km, and effect of satellite ephemeris reference framework was usually negligible for the control network baseline calculation; for obtaining CGCS2000 production, the problem about the type of satellite ephemeris, reference framework and epoch was negligible; non-ITRF97 and non-epoch 2000.0 production could be converted to CGCS2000 production by reducing calculus production with framework conversion formula and parameter.
