北斗卫星导航系统单历元定向算法研究

Research on Single Epoch Orientation Algorithm of BeiDou Navigation Satellite System

  • 摘要: 首先对北斗定向中附有基线长度约束单频单历元模糊度确定方法和双频单历元模糊度确定方法进行了研究,并基于LAMBDA模糊度搜索方法,给出了相应的模糊度确定方案。然后利用多组实测数据,对北斗定向模糊度确定的成功率、定向精度进行了测试和分析,结果表明目前北斗在定向的性能和精度上略低于GPS,但是处于一个数量级,已经可以满足多种应用的需求。

     

    Abstract: This paper first proposes a method for the BeiDou orientation using single epoch single frequency ambiguity resolution with fixed baseline length and single epoch dual frequency ambiguity resolution based on LAMBDA algorithm.According to the results of multiple tests on BeiDou and GPS short baseline data,the BeiDou’s ambiguity resolution success rate and the precision of orientation are found to be in common with the GPS’s.
