Abstract

This paper introduced the conceptions concerning GPS height system, such as geodetic,orthometric and normal height system and deflection of the vertical. The application of GPS altimetry and differences between GPS height and levelling height were analyzed. At last, GPS height fitting and the correction of height anomaly were discussed.
