%X As an application and test of GPS/Gravity boundary value problem, a local geoid located on N area is determined, by using 702 GPS/Gravity data for calculation and 52 GPS/Leveling for matching and checking. The accuracy analyses by matching with GPS/Leveling data and by direct correction to system difference show that the determination of local geoid computed by GPS/Gravity data and method of GPS/Gravity BVP achieved centimeter accuracy.
