Using satellites, terrestrial and marine gravity data, Chinese high-precision gravity field model are studied to improve the accuracy of navigation and positioning. Utilizing satellite gravity and GPS, the precise orbit determination of the low-orbit satellites, and regional characteristics of the ionosphere are studied to improve the accuracy of the geodetic positioning.
