APPLICATION OF GENERALIZED EXTENDED INTERPOLATION METHOD IN GPS HEIGHT TRANSFORM
广义延拓法在GPS高程转换中的应用

For solving the problems in the sub-regional riging up of the sub-regional fitting and transforming GPS height into normal height,this paper uses the generalized extension interpolation method in the large or complex area of to pographic change in GPS height conversion.Practical examples show that,by use of this method, the accuracy of GPS height conversion can be improved and the sudden step change can be avoided as well.
