[0003] Chinese patent CN201410160830.0-"Aeromagnetic measuring device and measuring method based on fixed-wing unmanned aerial vehicle", CN104808250A-"Aeromagnetic detection device and method based on unmanned aerial vehicle" all describe a fixed-wing based The UAV aeromagnetic measurement device is more suitable for aeromagnetic measurement with a large area. The fixed-wing UAV aeromagnetic measurement device has high requirements for the take-off site and cannot fly and hover at low speed. It is not suitable for archaeology, rivers, etc. Small-area aeromagnetic survey occasions such as pipeline detection and unexploded ordnance search

In addition, this type of UAV aeromagnetic measurement device adopts the current general-purpose software automatic magnetic compensation, which has limited ability to compensate for the huge magnetic interference of unmanned platforms.
