摘要
大型无人机的航姿系统、大气数据系统及惯性导航系统等导航设备因结构复杂、体积、重量大及价格昂贵等因素,无法在微型无人机(MAV)上使用。本文采用PC104嵌入式微机、MEMS集成技术、数据融合技术及GALILEO技术,实现了一种用于微型无人机的微型组合导航传感系统。以C语言及汇编语言作为系统软件的开发平台,增强了系统软件的可维护性及可扩展性。该系统集飞机航姿系统、大气数据系统、惯性导航传感器等功能于一身。实验室和现场的测试结果表明,该传感系统提高了导航精度,简化了结构,缩小了体积,减轻了重量。该系统拟用于微型无人机。
Navigation instruments of unmanned air vehicle （ UAV）, such as the attitude heading system, air data system and inertial navigation system, can＇ t be applied in the micro unmanned air vehicle （MAV） owing to their complicated structure, big volume, heavy weight and high price. In this paper, PC104 embedded microcomputer, MEMS integrated technology, data fusion, and GALILEO technology are employed for implementing MAV the micro integrated navigation sensing system. As a programming tool, Microsoft C and assembly language are utilized for the system software which maintainability and expansibility are improved. The functions of attitude heading system, air data system, and inertial navigation system are integrated in this sensing system. The testing results in laboratory and field indicate that the navigation precision of this sensing system is improved and it is smaller in volume and lighter in weight. This sensing system will be employed in MAV.
