摘要
主要讨论微小型惯性导航系统的工程设计问题。以微机电惯性测量元件(MEMS-IMU)为惯性传感器,以数字信号处理器(DSP)为核心作为导航计算机,设计构造了一种微小型捷联惯性导航系统。给出了系统的硬件结构框图和程序设计流程图,并讨论了DSP软件设计和调试中的一些问题。利用本方案,对于实现军事和工程领域中导航系统微小型化、降低系统成本和体积具有重要意义。
This paper describes some engineering designing problems of the miniature sized inertial navigation system and designs a miniature sized strap-down inertial navigation system use micro electronic mechanical system inertial measurement unit （MEMS-IMU） as the inertial sensors, and the digital signal processors （DSP） as the kernel of the navigation computer. The hardware architecture and the sofiware flow chart are offered, and then some problems of the designing and debugging DSP programs are discussed. It will be much advantaged to miniaturize the inertial navigation system in the military and technical field so as to reduce the system cost and size.
