基于一类新小波函数基的GPS相位观测值周跳探测

GPS Phase Measurement Cycle-Slip Detection Based on a New Wavelet Function

  • 摘要: 阐述了可通过1个参数因子来调节前后差分点个数的思路,研究了利用小波分析来平滑原始资料和探测GPS相位观测值周跳的方法,并通过CHAMP卫星实测数据进行分析,得出一些有益的结论。实践表明,该方法提高了周跳探测的有效性。

     

    Abstract: A new idea is put forward that the number of difference point can adjust by a parameter factor.The authors study this method to smooth raw data and detect cycle-slip with wavelet analysis.Taking CHAMP satellite data for example,the authors get some significant conclusions.It is showed that it is valid to detect cycle-slip in GPS phase measurement based on this wavelet function;and it is helpful to improve the precision of GPS data pre-processing and positioning.
