摘　　要：为了提高导航系统的服务质量,使导航系统在复杂环境下仍可以提供精确的定位导航与授时(PNT)服务,提出了一种微惯性测量单元(MIMU)、全球卫星导航系统(GNSS)、里程计模块(ODO)、高度计和航姿仪模块的组合导航系统硬件设计方案。为了提高系统的自适应能力,设计了基于CAN总线的即插即用模块。介绍了各个模块的特性和配置方法,完成了组合导航系统的底层驱动设计。在真实路段进行了跑车实验,实验表明该设计可以得到精准的位置和速度信息。In order to improve the service quality of navigation system,the navigation system can still provide precise positioning navigation and time( PNT) service in complex environment,a hardware design scheme for integrated navigation system based on micro inertial measurement unit( MIMU),global navigation system( GNSS),odometer module( ODO),altimeter and attitude meter module is proposed. In order to improve the adaptive ability of the system,a plug and play module based on CAN bus is designed. The characteristics and configuration methods of each module are introduced,and the bottom driver design of the integrated navigation system is completed. The results of experiments on real road show that the design can get accurate position and speed information.
