GPS／Galileo多模局域增强系统方案探讨

Study on the Scheme of GPS / Galileo Multi -LAAS

本文阐述了综合利用多个卫星导航系统的优势，通过分析得出综合利用多个卫星导航系统可以提高导航的精度、完好性、连续性和可用性；研究了GPS和Galileo局域增强系统的体系架构和数据处理流程，通过分析探讨得出多模局域增强系统具有可行性。

The advantages of utilizing synthetically multiple satellite navigation systems are described in this paper. Based on the analysis, we conclude that the utilization of multiple satellite navigation systems can improve the navigation accuracy, integrity, continuity and availability. The architecture and data processing/low of GPS and Gali- leo multi - LAAS are studied. It is proved that the multi - LAAS can provide a better perform and the multi - LAAS is feasible.
