It's desirable to obtain high accurate geodetic heights with GPS technique. But in the traditional geodetic control network the height system is used to based on the geoid. In this paper, we try to introduce the ground gravity data to convert the geodetic heights into elevations, based on the brons' formula.N =T/γ. In the paper, given is the observational equations of GPS observations, the elevations and coordinates of old geodetic points, and the ground gravity data. And the least square colocation method is adopted to estimate the geodetic coordinates, elevations, and the geodetic disturbance.
