Modeling of GPS multi-path signals and receiver testing

Yang Wei Zhao Yun Kou Yanhong Huang Zhigang(School of Electronics and Information Engineering,Beijing University of Aeronautics and Astronautics,Beijing 100191,China)  
The multi-path effect is one of the most important sources of positioning errors for global positioning system(GPS) and other satellite navigational systems.Multi-path signal modeling and its mitigation techniques have always been hot spots in the satellite navigation research direction.According to the multi-path signals nature,a specular reflection multi-path model was proposed,due to the influence of the specular reflections on GPS positioning accuracy more noticeable in comparison with other multi-path reflections.The pseudo-range measurement error of the GPS software receiver caused by the multi-path signals was tested.In the test,the multi-path signals were generated by this specular reflection model.The test results show that the pseudo-range error changes caused by the multi-path signals act in accord with the theoretical analysis curves.
