为了满足卫星导航接收机整机性能快速、精确测试的需求,实现对导航接收机性能的自动测试,构建了一种基于NI PXI硬件平台,采用导航信号模拟器、虚拟仪器技术和Microsoft Visual Studio 2008软件进行开发的卫星导航接收机自动测试系统。系统实现了多导航接收机的定位精度、冷启动首次定位时间、热启动首次定位时间、捕获灵敏度、速度精度的并行自动测试。良好的人机交互界面与多接收机并行测试的稳定运行,大大缩短了测试时间,提高了测试效率。通过对北斗导航接收机大量测试,结果表明该卫星导航接收机快速测试系统对于导航接收机整机性能并行测试快速、有效。
In order to achieve the automatic test of navigation receivers with the requirements of rapid and accurate testing satellite navigation receiver performance, this paper builds a navigation receiver automation test system, which based on satellite signal simulator, virtual instruments and Microsoft Visual Studio 2008 as a software developer, and National Instruments PXI hardware platform. System has realized the position precision, cold start time to first fix, hot start time to first fix, capture sensitivity and the velocity precision of navigation receiver parallel automatic test. The extensive test results of Beidou navigation receivers show the automation test system is fast and effective for navigation receiver performance test.
