摘要
为解决“双星”定位系统不能实现无源导航的缺陷,提出近空间伪卫星概念,设计了基于近空间伪卫星的“双星”增强系统。分析了近空间伪卫星的需求,确定其活动区域和平台形式。提出近空间伪卫星自身定位的几种形式,比较各自的特点,确定可行方案。不仅提供了一种三维无源导航资源,而且对近空间领域的开发,以及对近空间飞行器的应用提供了更具潜力的发展方向。
The double satellites navigation system in the standalone mode cannot accomplish real -time three dimensions（3 - D） passive navigation due to the limited number of satellites. In order to meet the passive 3 - D navigation demand, the near - space pseudolite is proposed. The double satellites augmenta- tion system based on near - space pseudolite is put forward and designed. The near - space pseudolite＇s motivation, scope, platform and applicability is analyzed or established in details. ,Several schemes of near - space pseudolite positioning for itself are put forward. By comparing these schemes, the feasible one is determined. It is important to recognize that the near - space pseudolite not only can meet the desire of 3 - D passive navigation currently, but also has important application merits for future near -space vehicle systems.
