【摘要】：随着卫星导航技术的不断发展，卫星导航产品在越来越多的领域得到应用，，近几年我国卫星导航系统建设也在紧锣密鼓的推进，用户设备的研制和生产得到极大的促进，但设备性能却良莠不齐。为保障用户设备行业健康、快速发展，建立一套严格的设备测试规范，并科学准确的完成对用户设备工作性能的评价意义重大。 本文首先介绍了卫星导航接收机测试系统的基本构成和工作方式，并针对GNSS基本型接收机主要性能指标的测试方法进行了相关研究。通过分析两种不同工作方式下的接收机的工作原理，以及各个测试项目与接收机性能之间的关系，分别对RNSS的灵敏度、测距码捕获时间、测距精度、首次定位时间、多通道时延一致性、定位测速精度、自主完好性测试以及RDSS的误码率、双向零值和测距精度、定位功能、定位成功率、通信功能以及位置报告功能等进行分析，研究了各项指标的测试方法，并对测试过程中产生的数据进行预处理，分析评估测试结果的方法并制定测试流程。在此基础上，利用SQL2000建立了测试系统数据库，并在C#.NET平台上开发了用户设备测试数据评估软件，实现了自动批量对用户设备的评估计算。
[Abstract]:With the continuous development of satellite navigation technology, satellite navigation products have been applied in more and more fields. In recent years, the construction of satellite navigation system in our country has also been vigorously promoted, and the development and production of user equipment have been greatly promoted. But the performance of the equipment is mixed. In order to ensure the healthy and rapid development of the user equipment industry, it is of great significance to establish a set of strict equipment testing standards, and to scientifically and accurately complete the evaluation of the working performance of the user equipment. In this paper, the basic structure and working mode of the satellite navigation receiver test system are introduced, and the test methods of the main performance indexes of the basic GNSS receiver are studied. By analyzing the working principle of the receiver under two different working modes and the relationship between each test item and the performance of the receiver, the sensitivity of the RNSS, the acquisition time of the ranging code, the ranging accuracy, the first positioning time, respectively, are analyzed. Multi-channel delay consistency, location-velocity measurement accuracy, autonomous integrity test, bit error rate of RDSS, bidirectional zero value and ranging accuracy, location function, location success rate, communication function and position reporting function are analyzed. The test methods of each index are studied, and the data generated in the test process are preprocessed, the method of evaluating the test results is analyzed and the test flow is established. On this basis, the test system database is established by using SQL2000, and the evaluation software of user equipment test data is developed on the C#.NET platform, which realizes the automatic batch evaluation and calculation of user equipment.
