全球定位系统用户定位的数学模型

以卫星时钟、系统时钟、用户接收机时钟同步为条件,建立起用户接收机位置求法定性分析的基本原理;又从三者时钟非同步开始建立起用户接收机位置求解的数学模型,在线性化的基础上,用迭代法进行位置求解的定量分析,使之对全球定位系统用户定位有一个比较清晰的认识.

Mathematics Model of Global Positioning System for Locating Users

This article introduced basic principle of user's receiver position calculation and analysis that is based on the condition of synchronization of satellite timing;system timing and user's receiver timing.A math- ematics model is established based on above three timing factors in insynchronization condition.Also we ana- lyzed position calculation in mathematics methods.From this article the GPS receiver user's can clearly under- stand the GPS.
