摘要
CAPS气压测高可以获取用户所在位置的高度,结合该气压测高技术,CAPS利用同步轨道(GEO)上的通信卫星构建导航星座实现用户的三维定位。针对区域用户,本文给出了CAPS气压测高的工作流程,并结合实测的气象参数,仿真分析了测高的精度。结果表明,仿真分析与实测的结果基本一致,CAPS气压测高的精度可以满足一般导航用户的需求。
CAPS barometric altimeter can be used to obtain user＇s altitude.Combining with barometric altimetry technique,the CAPS user realize three-dimensional positioning based on geostationary orbit（GEO） communication satellites.In this present paper,the authors introduce work process of barometric altimetry in a region and make simulation analysis of altimetry precision with actual meteorological data.The results show that altitude from simulation analysis is consistent with altitude measurement value,and the precision of CAPS barometric altimeter can meet the need of general navigation users.
