摘要
Abstract
In GPS leveling survey, the geodetic height surveyed by GPS needs to be transferred to normal height. In order to improve the transferring accuracy, the non -parameter component is introduced into the plane fitting model by using natural spline model. Based on the established model by introducing non-parameter component, using the data of a D-class control network, the accuracy of the model fitting is analyzed. The analysis results show that selecting the appropriate regularization ma-trix and smoothing factor can improve fitting accuracy of normal height.关键词
