| 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。 |

| Double Satellites Augmentation Positioning System Based on Near-Space Pseudolite |
|
| () |
| Abstract: |
| The double satellites navigation system in the stand-alone 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 augmentation 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. |
