Using Accumulated Errors to Realize Close-Loop Rectification of Integrated Navigation System

用误差估值累加实现组合导航系统的闭环校正

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。

MAV has many kinds of special functions such as GSP autonomous navigation, super close distance reconnaissance, target location, reconnaissance over barrier, battlefield monitoring, close distance electronic interference, obtaining information of battlefield and abstracting deleterious matter.

MAV具有GPS自主导航和超近距离侦察、目标定位、越障侦察、战场监控、近距离电子干扰，战场信息获取、有害物质提取等多种特殊功能。
