Analysis of Creating Correction Algorithms for GPS Network RTK System

Abstract:

In order to analyze the effect of using different creating correction algorithms and geometry of reference stations on the correction accuracy of a user station, interpolation coefficients (correction quality factors) were calculated based on six algorithms, three experiment networks and two users in different positions. These algorithms include Partial Derivative Algorithm (PDA), Distance-based Linear Interpolation Method (DLIM), Linear Interpolation Method (LIM), Low-order Surface Model (LSM), Linear Combination Model (LCM) and Least - Squares Collocation (LSC). By comparative analysis on these factors a conclusion can be drawn as follow, LIM and LCM algorithms are better than others in creating correction; the geometry of reference stations involved in calculation needs to be carefully considered.
