摘　　要：以往导航精度试飞采用基于参数估计理论的误差统计法,须完成规定的试飞架次才能得出试飞结论。这里根据假设检验理论总结出序贯概率比检验法,在给定置信度和误差概率时,求出导航精度的拒绝域、接收域和观察域;当试验曲线收敛于接收域时即可提前结束试飞,达到节省架次的目的。通过应用表明该方法不但适用于导航系统,对其他系统也具参考价值。The error statistical method based on theory of parameter estimation used in navigation precision flight test can not gain test conclusion until the scheduled flight testing sortie are completed. The sequential probability ratio test method is pro-posed in this paper according to the testing hypothesis theory,by which refused region,received region and observed region of navigation precision can be deduced while the confidence level and error probability are stipulated. The test may be permitted to be closed ahead of schedule only when test curve converges to the received region,and the flight test sortie is saved then. The method not only is applicable to the navigation systems but also has a reference value to other systems.
