摘　　要：多基准一致性检测方法用于检测局域增强系统地面子系统产生的差分修正量的一致性，在处理过程中对每个基准接收机观测的伪距进行载波相位平滑，根据伪距修正量计算B值，并与门限相比得出结果。多基准一致性检测实现了对地面子系统基准接收机测量的伪距修正量误差较大的通道进行检测和排除。Multiple reference consistency check（MRCC） is used to check the consistency of the differential corrections that calculated by local area augmentation system ground facility. The processing applies carrier phase to smooth the pseudorange that measured by every reference receiver, then calculates B value via the pseudorange corrections, and gets results by comparing with the thresholds. The MRCC can check and exclude the channels that have failed pseudorange corrections that measured by ground facility reference receivers.
