本研究旨在评估惯性导航系统的性能。为此，我们全面研究了12种计算圆误差概率（CEP）的方法。使用数据处理技术，我们将这些方法分为三类：一维变量的参数化，双正态随机变量的计算，和数值积分。从这些方法中，我们开发的算法和程序，随后应用于评估导航系统的定位精度。使用的算法和程序，我们进行模拟，以评估在相同的初始条件下的适用性和评估精度。最后，利用实际测试数据对结果进行了验证.在对各种方法进行比较的基础上，提出了一种综合考虑样本数量和评价精度的实用方法。我们的研究结果作为一个理论参考的发展不同的方法来评估惯性定位精度，按照适用的标准。
This study aims to evaluate the inertial navigation systems’ performance. To this end, we comprehensively investigate 12 methods for calculating the circular error probability (CEP). Using data processing techniques, we classify these methods into three categories: parameterization of one-dimensional variables, computation of bi-normal random variables, and numerical integration. From these methods, we develop algorithms and programs, which are subsequently applied in evaluating the positioning accuracy of navigation systems. Using the algorithms and programs, we perform simulations to evaluate applicability and evaluation accuracy under the same initial conditions. Practical test data are employed to validate the results. Using the comparison of the methods as bases, we put forward a comprehensive practical method regarding sample number and evaluation accuracy. Our results serve as a theoretical reference for the development of different approaches to assessing inertial positioning accuracy in accordance with applicable standards.
