Abstract
Through the connection surveying of 25 GPS points of the fourth-grade leveling,the paper calculates the normal height of the points by using the polynomial fitting model and the polyhedral function fitting model, compares the normal height with the results of the fourth-grade leveling,obtains the beneficial conclusions,which has the guiding significance for the practical production of GPS.
