Research on the Optimization model of GPS Elevation Fitting in Jiaozuo;

Based on the analysis of several mathematical methods for GPS elevation fitting,this paper provides corresponding mathematical models.

Application of BPSA hybrid strategy in GPS height fitting;

GPS height fitting uses this principle to extract normal height,in the paper,the principle and superiority of curved surface spline func- tion interpolation are discussed,the GPS height fitting is carried,and the known points are validated,as re- sults,it is reliable,and the method is feasible and effective,has a certain scientificalness and practicability.

When implementing GPS height fitting, if the parameters of the functional model or the weight matrix of the stochastic model are not rational, the mathematical model will not agree with the fact.

Based on terrain,the theory of artificial neural network is used in this paper for GPS height collocation.
