Abstract

In the future, when Vietnam builds successfully national space coordinate reference system VN2000-3D (Dynamic Coordinate System), after a period of using, there will be a need to develop and expand the baseline GNSS geodetic network (building more new base stations using GNSS technology). At this time, we can completely use old and new measurements to adjustment the entire network. However, this approach is not useful in terms of time, economics and not consistent with the advancement of theory of data processing of modern geodetic network. This paper presents the theoretical and empirical results of the recurrent adjustment and rotational transformation (T- algorithm) to update GNSS measurements according to modern treatment approaches of geodetic network data without having to adjust existing GNSS network to meet the modern requirements of the national geodetic information system.
