Design of ATS for INS/GNSS strapdown inertial navigation system based on virtual instument technology

捷联惯性/GNSS组合导航系统是飞机定位和导航的重要机载电子设备;但是开发具有模块化、柔性、通用性和远程控制和测试功能的通用自动测试平台,却是一个难题。文中在简要介绍虚拟仪器技术的基础上,提出用虚拟仪器技术开发通用自动测试系统的设计方法;详细介绍了捷联惯性/GNSS组合导航系统测试系统的软硬件设计,重点分析了设计中难点问题及其解决方法。通过实际测试和评估,该综合测试系统性能稳定、可靠,操作方便,界面友好。

INS/GNSS strap - down inertial navigation system is an important equipment for orientation and navigation ;but the design of the universal automatic test system with the characters of modularization, remote control and test capability is a problem. In this paper, the way to design the universal automatic test system is brought forward, with the virtual instrument technology narrated. A way how to realize the ATS based on virtual instrument technologies from the hardware structure and software system and the key point problems are also analysed. The application result indicates that the character of this test system is steady, reliable and easy to handle.
