Abstract:

According to current research trends in the world, the construction and improvement of the vertical datum system must be based on geoid/quasigeoid surface with high accuracy, thereby building a foundation to apply GNSS high measurement technology. The paper presents research and evaluation of accuracy of global gravity models from GOCE and EGM2008 satellite data. Since then, combining the lowharmonic function coefficients of the GOCE satellite gravitational model with the higher order of EGM2008 model as well as GPS - TC data of 155 the points of state grade I, which has built for the Vietnam region and surrounding areas quasigeoid model with an accuracy of ± 8.2 cm.
