So it's always a hot topic how to transform GPS ellipsoidal height into level elevation and to keep certain accuracy.
如何将GPS大地高转化咸水准高程，并使其保持一定的精度，一直是人们研究的热点。
The accuracy of Orthometric Height will be directly affected by ellipsoidal height precision during GPS height transformation, therefore, the detection of gross error is very important.
GPS高程转换中，大地高的精度将直接影响转换后正常高的精度，为此大地高的粗差探测是比较重要的一个环节。
In this paper, we study a new kind of stochastic process from the family of distribution of ellipsoidal equal height, that is, the process of ellipsoidal equal height.
