Higher-order Ionospheric Error Correction for Precise Point Positioning

  • 摘要: 描述了高阶电离层误差对精密单点定位(precise point positioning,PPP)的影响公式,并通过实验分析了该误差对PPP静动态定位的影响。数值结果表明,改正电离层高阶项误差可以mm级提高PPP静动态定位精度和缩短动态定位的收敛时间。

     

    Abstract: Ionospheric delay is one of the main error sources in GNSS positioning.This paper describes a formula derived to correct higher-order ionosphere error of L3 observation and analyzed the effects on the static and kinematic positioning accuracy.Numerical results show that correcting the higher-order ionospheric error improves the PPP static and kinematic positioning accuracy and shorten the convergence time of PPP kinematic positioning.
