Ø  Marine optical fiber cable survey in a coastal area of Guangdong
Through this UAV ultra-low altitude aeromagnetic survey operation, the accurate positions and extension directions of nearshore submarine cables and optical fiber cables were detected. This operation aims to accumulate experience in exploring magnetic detection methods for pipelines in complex environments such as nearshore and shallow intertidal zones, and to master relevant technologies of the aeromagnetic system in this field. It also provides practical technical support and guidance for the subsequent application of UAV ultra-low altitude aeromagnetic survey in this direction, while exploring ideas for its application in fields such as underwater archaeology and shipwreck investigation.
