中文摘要：

将QUAD方法用于接收机自主完好性监测的故障检测与排除,结果表明该方法进行卫星导航系统多故障的定位与定值是基本可行的,但该方法实际应用于涉及生命安全的民用航空领域还需要进一步验证。

英文摘要：

The QUAD method is used for fault detection and exclusion in GNSS receiver autonomous integrity monitoring.The results show that QUAD method can be used for multiple faults detection and exclusion in satellite navigation system.However,the performance of QUAD method still needs test and verification,especially in safty-critical applications.
