    • Systems and methods for reducing error detection latency in LPV approaches are provided. In certain embodiments, a method for navigational guidance includes calibrating inertial measurements acquired from an inertial navigation system with satellite-based augmentation system position measurements acquired from a satellite-based augmentation system to create corrected inertial navigation system positions. The method also includes determining whether the satellite-based augmentation system experienced a fault when the inertial measurements were calibrated with the satellite-based augmentation system position measurements. Further, when the satellite-based augmentation system did not experience a fault, the method includes monitoring the satellite-based augmentation system navigation position measurements based on the corrected inertial navigation system positions.
    • 提供了用于降低LPV方法中的错误检测延迟的系统和方法。 在某些实施例中,用于导航指导的方法包括校准从惯性导航系统获得的惯性测量,其具有从基于卫星的增强系统获取的基于卫星的增强系统位置测量值,以创建校正的惯性导航系统位置。 该方法还包括当使用基于卫星的增强系统位置测量来校准惯性测量时,确定基于卫星的增强系统是否经历故障。 此外,当基于卫星的增强系统没有遇到故障时,该方法包括基于校正的惯性导航系统位置监视基于卫星的增强系统导航位置测量。
