GEO和IGSO卫星增强GPS性能的仿真分析
Simulations and analysis of performance for GPS enhanced by GEO and IGSO
摘要
Abstract
A method for enhancing the performance of GPS in Asia & Pacific is presented. It adds the GEO( Geostationary Earth Orbit) & IGSO(Inclining Geostationary Synchronized Orbit) satellites to the GPS constellation, and then analyzes the visibility and PDOP in the enhanced area. Compared with the same parameters on a global scale, it is concluded that the positioning accuracy and availability of GPS are increased owing to the enhanced GEO & IGSO satellites.关键词
