基于北斗导航卫星的伪卫星技术在区域定位中的应用

借鉴差分 GPS导航定位的原理 ,阐述了在北斗导航卫星支持下的伪卫星技术 ,探讨了其定位原理、系统配置、技术设计、信号结构、天线安装和使用条件等。实现区域快速无源导航定位 ,需要至少四个伪卫星站提供的导航信号。伪卫星定位导航具有自主、隐蔽、经济等特性 ,在区域定位中应用前景良好。

An Application of Pseudo Satellite Technology Based on the BeiDou Navigation Satellite in Local Positioning

After drawing lessons from the principle of DGPS, this paper expands pseudo satellite technology based on the BeiDou satellite navigation, then probes into its institute of positioning, system disposition, technology design, signal organization, antenna installation and condition of employment,etc.To bring about local navigation and position, it at least requires navigation signals from four pseudo satellite stations. Because of its characters of independence, secret, cheap and so on, it should be well used in local positioning by means of pseudo satellite.
