Chapter 14 Positioning Error Research and Analysis Based on Comprehensive RDSS Method

摘要

Comprehensive RDSS positioning method is a combined positioning method, using the pseudo range difference between a RDSS repeater satellite and any other two navigation satellites to calculate the position information of the users. This method has become an important research direction of global satellite navigation to improve the ratio of cost and efficiency, reduce the user machine complexity and improve the positioning accuracy. In this paper, combined positioning accuracy error source, including satellite constellation, measurement error and multi-path effects is analyzed by the comprehensive RDSS method. On the same time, the method to eliminate and weaken the influence of errors on the positioning precision is also proposed.
