Abstract:

Through analysis on the principle of GPS height measurement,we introduce common method of GPS height measurement,base on different network of GPS control survey grid,we obtain two mainly methods of elevation model fitting,polynomial curve fitting and polynomial surface fitting,and propose the main measurements and methods to improve accuracy of GPS height measurement.

Key words: GPS, Height measurement, Height anomaly, Geoid model
