车载导航接收机性能测试与分析

Testing and Analysis of Vehicle Navigation Receiver Performance

高精度定位技术是智能网联汽车正常工作的重要保障之一。随着全球卫星导航技术的不断发展,卫星导航接收机的性能评估与测试也更加重要。目前,相关国家标准针对定位性能有着明确的要求,但并未给出明确具体的测试说明。本文以车载导航接收机为对象研究其性能测试的具体方法。论文从仿真测试和实车道路测试两个方向进行研究,分别列举测试项目并针对测试数据进行分析,提出了切实可行的车载导航接收机测试方法。

High precision positioning is an important guarantee for the normal operation of Intelligent and Connected Vehicle( ICV). With the continuous development of global satellite navigation technology, the performance evaluation and test of receiver become more important. At present, the relevant national standards have clear requirements on the positioning functions. However, no specific test instructions are given. In this paper, the vehicle navigation receiver has been studied, with emphasis on the performance testing method. This paper studies the simulation test and real vehicle road test, lists the test items and analyzes the test data, and puts forward a feasible test method for vehicle navigation receiver.
