分析了流行的歧义比率测试的性能。基于实验和模拟数据，鉴于未来全球导航卫星系统（GNSS）歧义分辨率将带来的，当前对固定临界值的当前使用率使用固定临界值的使用是不可持续的。作为替换，提出了具有固定故障率的模型驱动比率测试。描述了该固定失败率检验的特征，并给出了性能分析。还研究了其临界值与各种GNSS模型参数之间的关系。最后，为创建比率测试的临界值创建固定故障率查找表的过程。
The performance of the popular ambiguity ratio test is analyzed. Based on experimental and simulated data, it is demonstrated that the current usage of the ratio test with fixed critical value is not sustainable in light of the enhanced variability that future global navigation satellite system (GNSS) ambiguity resolution will bring. As its replacement, the model-driven ratio test with fixed failure rate is proposed. The characteristics of this fixed-failure rate ratio test are described, and a performance analysis is given. The relation between its critical value and various GNSS model parameters is also studied. Finally, a procedure is presented for the creation of fixed failure rate look-up tables for the critical values of the ratio test.
