基于蜂窝构型的空基伪卫星定位网络
Pseudolite Positioning Network Based on Honeycomb Distribution
摘要
Abstract
Pseudolite offers additional navigation signal based on non-satellite platform,working with existing navigation satellite system or alone,can effectively improve navigation performance. The geometric distribution of pseudolites produces great effect on posi- tioning performance and application. Considering the characters of pseudolite network based on medium/high altitude aircraft,the paper gives a high/low attitude honeycomb distribution and simulation results of visibility,near-far effect and dilution of precision（DOP）. The results show that the honeycomb distribution network has advantages of great coverage area,easy extension and low DOP,which can im- prove the positioning performance in the navigation service area.关键词
