Abstract
A new geodetic boundary value problem: GPS/Gravity-BVP is studied in this paper. Firstly, the definition and integral equation of GPS/Gravity-BVP are given, then an approach solution of GPS/Gravity-BVP is obtained. Also, the formulas for determining quasi-geoid, deflections of the vertical and external gravity field are given by use of the solution of GPS/Gravity-BVP. Furthermore, the advantages and problems of GPS/Gravity-BVP in physical geodesy are discussed.
