Abstract: The paper proposes a new algorithm to unify height datums in different regions, which is based on the solution of the linearized fixed-gravimetric boundary value problem. Compared with traditional methods, this method uses GPS ellipsoidal height and gravity disturbances on the surface of the earth to obtain a quasigeoid, which is not related to any local vertical datums. As an example, we calculate the height datum difference between Shenzhen and Hong Kong by applying this new method. The result shows that the height difference obtained by this new method is consistent with the ground leveling result to a few centimeters.
