利用信噪比削弱多路径误差的方法研究

Mitigation of Multi-path Effect Using SNR Values

    摘要
  • 摘要: 多路径效应是卫星导航定位中重要的误差源,在分析多路径效应的产生原理以及多路径效应与信噪比相关性的基础上,提出了可利用信噪比削弱多路径效应的方法,并利用自测的GPS观测数据进行了验证。

     

    Abstract: Because multipath is not spatially correlated,it can not be canceled with different techniques.The bias-like multipath remains the dominant error source for different measurements.According to the quality of each carrier phase measurement is contained in the signal-to-noise ration(SNR), a method using SNR values with GPS carrier phase observable in the presence of multipath is developed.And the experimental result is carried out.
