| Abstract: | A mathematic model to solve the GPS normal height with elevation fitting is described and the feasibility to substitute leveling survey with GPS elevation fitting is discussed in light of the practice of use of the model in the waterway regulating project for Lianyungang Port.The practice proved that,under certain circumstances,the GPS height fitting can reach the accuracy of leveling survey of a certain grade and meet the requirements for control surveys in waterway works. |
