Embodiment Construction
[0030] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0031] Capturing and recovering drones through damping nets and damping ropes on the mobile platform can greatly improve the recovery efficiency and deployment capabilities of drones, and make full use of the limited range of drones, especially small drones. The flight time capability improves the efficiency of the UAV. For this new recycling method, there are new requirements for UAV control.
[0032] The UAV is equipped with sophisticated (visible light, infrared) optical equipment and cooperative targets near the recovery point to obtain guidance information. The reliability of this method is seriously affected by visibility conditions, which affects the attendance rate of the UAV, and the relevant software is quite complex.
[0033] By equipping the recovery platform with a complex radio guidance system or radar system to obtain ...

The invention relates to a double satellite receiver-based unmanned aerial vehicle homing recovery guidance control method. Double satellite positioning receivers are mounted at an unmanned aerial vehicle and a recovery point respectively; homing recovery means that the unmanned aerial vehicle is intersected with a specific target through control constraint, so that the aim of recovering the unmanned aerial vehicle is achieved. The unmanned aerial vehicle homing recovery guidance control method comprises a guidance information acquisition method, a control method in an unmanned aerial vehicle homing process, and a go-around strategy for preventing collision of a carrier of a recovery mechanism and the unmanned aerial vehicle in an abnormal condition. The unmanned aerial vehicle is guided and controlled by the method to impact recovery mechanisms, such as an obstruction net or an obstruction rope, which are deployed on moving ships and vehicles, so that the inconvenience that the recovery guidance system is required to be equipped with complex guidance equipment generally or is influenced by visibility is solved, and the requirement for recovering the unmanned aerial vehicle safely and precisely is met.
Description
technical field [0001] The present invention relates to a recovery and guidance control method based on dual satellite receivers for unmanned aerial vehicles, which can guide and control the rendezvous between the unmanned aerial vehicle and the target by indirectly measuring the line-of-sight angular rate of the unmanned aerial vehicle relative to a specific target. The purpose of recovery is mainly the precise recovery of UAVs on mobile platforms. Background technique [0002] UAV recovery guidance control technology is the basis for UAV reuse. Most drones are recovered by parachute recovery or airport runway. Small UAVs are generally recovered by parachute, and large and medium-sized UAVs are generally recovered by airport runways. When using parachute recovery, the recovery accuracy and efficiency of the UAV are seriously affected by the wind field. When used on land, it is restricted by the topography of the recovery site. When used at sea, it is also necessary to con...
