Research on Improving GNSS Level Fitting Accuracy of Multi-Faceted Function

Abstract:

We use various multi-faceted functions to improve fitting accuracy of GNSS level fitting. Propose a method to select kernel function, determine smooth coefficient and a law to choose kernel function node for improving fitting accuracy. We give a formula to calculate smooth coefficient and test it in plain area. The formula has practical significance to improve fitting accuracy and stability of the results.
