基于北斗数据的非差相对定位理论与方法研究

摘要

简要介绍了北斗导航定位系统，论述了非差相对定位的基本概念、原理及建立非差相对定位模型的基本原则，介绍了建立单历元非差相对定位模型的函数模型和随机模型的详细过程，利用 LAMBDA 方法实现基线单历元模糊度的固定。对单历元非差相对定位的基线解算精度进行了重点分析。%Beidou system has been briefly introduced in this paper,basic concept of un differenced relative positioning has been discussed,and the principle for establishing un differenced relative positioning model has been introduced in detail.The detailed process for establishing the function and stochastic model of sin-gle epoch un differenced relative positioning model have been introduced.By using LAMBDA method, single ambiguity fix has been realized.The positioning accuracy of the baseline solution by using single ep-och relative model has been analyzed as well.
