| Abstract: | Which models can be used to predict optimum GPS Block IIR(M) satellite clock errors were researched in the case of few surveying data.The research shows that the accuracy for predicting in one day is a 1 ns and it in ten days is 10 ns with the GM(1,1)-AR(p) compound model.The prediction results with better than the results with quadratic polynomial model and GM(1,1) model and the accuracy is better than that from IGS(the International GPS Service for Geodynamics) of the accuracy of 7 ns.Because the atomic c... |
