利用码相二次差分与Jarque-Bera检验进行实时周跳探测

Real Time Cycle Slip Detection Based on Jarque-Bera Test Using Bi-differences of Code and Phase

    摘要
  • 摘要: 对伪距与载波相位观测值进行二次差分构造周跳检验参数,并利用Jarque-Bera方法对历元窗口内的周跳参数进行正态分布检验,较好地实现了周跳的实时探测。利用实测GPS静态数据以及车载GPS动态数据进行了周跳探测算例分析,结果表明,此方法能够实时探测出周跳,并能有效修复周跳。

     

    Abstract: A real time cycle slip detection method is proposed based on Jarque-Bera test for testing the normality of slip parameter in epoch window,which constructed by bi-differences of pseudo range and carrier phase observations.Real time cycle slip detection tests are analyzed with GPS static observation data and on-board GPS dynamic data.The results indicate that the algorithm can detect outliers in real time,and provide the base of data quality controlling for real time precision orbit determination and positioning.
