RESEARCH ON INTEGRATED NAVIGATION RAIM MODEL BASED ON CORRELATION ANALYSIS
摘要
Abstract
The principle,calculation method of correlation coefficient, and its significance test were described. Focusing on integrated navigation RAIM model, the integrated navigation RAIM method based on correlation analysis theory was probed, testing process of single and multiple gross errors detection was presented. By simulating the 12 GPS and Galileo navigation satellite positioning system, outliers were added to single and two satellites, respectively. Simulation results show that the correlation coefficient of observations' influence vector and residual error can locate and remove satellites which contain gross errors, improving the navigation positioning accuracy.关键词
