Reliability Analysis of RDSS and Research on Combined Enhancement Technique

文中通过对RDSS系统可靠性分析,提出了空间增强RDSS导航可靠性的途径和方法。在分析目前几种增强方案不足的基础上,提出了一种空间与用户联合增强技术,实现用户无节点无源导航。仿真结果表明:文中所提方法可有效改善RDSS导航可靠性。

The reliability of RDSS is put forward with respect to the analysis about RDSS system in this paper and the approaches to enhance RDSS reliability based on space segment are proposed. On the basis of the analysis about disadvantages of RDSS navigation, the space-user combined enhancement technique is proposed for user to realize the no-node and no-source navigation. The simulation result shows that the way can improve RDSS reliability effectively.
