Several main research methods used for path plan of loitering unit were analyzed and compared.

A loitering path planning method for an aircraft based on genetic algorithm is proposed.

To make the loitering unit fly from its current point to the target point in shortest way and meet the target finally on the attack stage,a disassemble planning method of three-dimensional ballistic trajectory is put forward.

The reconnaissance loitering search strategy of loitering munition was analyzed.

In this project, we devisethe loitering munition missile control system fully, including structure,control method,thehardware and software and so on.

To the problem of which traditional stervo control mode and control algorithm are not suitable to stervo controller of loitering munition,the paper brings forward one stervo controller to control three stervos model,and adopts three-loop control algorithm of position loop,velocity loop and current loop to realize stervo position control function.

Due to cruising missile s unique characteristics such as long flighting distance, various functionS,lasting long time when performing such missions as detecting, positioning, instructing, transmitting information, assessing destruction etc.

Part radiation and visible-light-malfunction can be found in flight-patrol.
