aerial navigation

Autonomous flight control system of Unmanned Aerial Helicopter ( UAH) is very important in autonomous flight. The relationship between flight control system and navigation system is close and tight. Navigation system provides accurate flight parameters for flight control system.

无人驾驶直升机能否实现自主飞行，关键在于飞行控制系统，而飞行控制系统又与导航系统密不可分，导航系统为飞行控制系统提供准确的飞行参数。

The development and maturity of navigation of GPS aerial photography, GPS and inertial measurement unit, airborne laser scanner, digital air camera etc technique, make today spatial.

GPS航摄导航、GPS及惯性测量装置、机载激光扫描技术、数字航摄仪等技术的发展和成熟，使得当今空间信息的获取比以往更为快捷、高效和精确。
