英文摘要：

In this paper, a measurements combination algorithms method used to monitor the integrity risk is proposed. The linear combination for the single statistic value and multi-receivers is discussed. A simulation test with the data collected from the Fang Shan observation station in Beijing is performed. The simulation results show that this algorithm can detect the faults more quickly and improve the detection speed. It also can detect some little deviation; decrease the miss-detection rates of the system.
