一种提高北斗导航定位终端安全性能的设计

A design for improving the safety performance of the Beidou navigation and positioning terminal

北斗卫星导航定位系统相较于GPS的无源定位模式(RNSS)来说可以同时兼容有源定位(RDSS),这使得北斗具备通信功能并且只需更少的卫星即可实现定位,但是有源定位存在信息泄露的风险,本文针对该问题提出了一种提高北斗导航定位系统使用安全性的设计。

Compared with the RNSS mode of GPS, theBeidou navigation and positioning system can be compatible with RDSS mode.This makes the Beidou system has a communication function and can achieve positioning function withless satellites,but the RDSS mode has the risk of information leakage.In this paper, we proposed a design method to improve the security of the Beidou navigation and positioning system.
