基于ARM的组合导航计算机系统方案设计

Integrated Navigation System Design Project Based on ARM

主要讨论嵌入式GPS/SINS组合导航系统的工程设计问题,以微惯性测量单元(MIMU)和GPS接收机作为传感器,以ARM(Advanced RISC Machines)为核心作为导航计算机,设计构造了一种嵌入式GPS/SINS组合导航系统,给出了系统的硬件结构框图和程序设计流程图,并讨论了软件设计中的一些问题,该方案对于缩短工程领域中导航系统的开发周期、增强系统扩展性、降低系统成本和体积具有重要意义。

Some engineering designing problems of the embedded GPS/SINS integrated navigation system are described. A embedded GPS/SINS integrated navigation system is designed using Micro-inertial Measurement Unit （MIMU） and GPS-OEM as the sensors, and the ARM （Advanced RISC Machines） as the kernel of the navigation computer. The hardware architecture and the software flow chart are offered, and then some problems of the designing are discussed. It will be much advantaged to shorten the development periods and strength- en the expansibility of the system in the technical field so as to reduce the system cost and size.
