摘要：

We use various multi-faceted functionsto improve fitting accuracyof 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.
