LAAS多参考站故障检测和排除方法

The Fault Detection and Exclusion Method for LAAS Multiple References

设计了LAAS (GPS局域增强系统 )参考站故障检测和排除方法 ;推导了多参考站伪距改正数误差及限值的计算公式。在任意B值排除方法的基础上提出了最大B值排除方法 ,通过分析得到 ,该方法有较好的完善性和连续性性能。

This paper designs the fault detection and exclusion method for LAAS multiple references, deduces formulas of pseudorange correction error and threshod. Based on any B value exclusion, the method of maximum B value exclusion is brought forward. It is concluded that this method has better performance of integrity and continuity.
