摘要
针对捷联惯导系统低成本、小体积的要求,提出一种利用微机械惯性传感器、以ARM芯片作为导航计算机的硬件方案。设计基于嵌入式实时操作系统的实时多任务导航计算机软件系统。测试结果表明,姿态角度的短期误差可保持在2o范围内,软件系统能合理分配硬件资源,提高导航计算机的整体性能,软件的模块化设计使导航计算机的软件系统具备良好可移植性。
Aiming at satisfying the requirements of low cost and miniaturization by Strap-down Inertial Navigation System（SINS）, a hardware scheme of MEMS inertial sensor and ARM chip based navigation compute is presented. An embedded RTOS-based software system for navigation computer is developed, Test results sbow that the attitude errors is less than 2 degree in short time period, the software system can operate hardware source properly and the performance of navigation computer is improved. Tbe modular software design facilitates the portability of software system of navigation computer.
