[0002] With the development of drone technology, low-altitude geophysical exploration has seen rapid growth, especially aeromagnetic technology, which has become the preferred choice for low-altitude geophysical exploration due to its light weight and easy magnetic field acquisition.

The acquisition host is placed at the geometric center of gravity of the drone's belly or top, and the probe is placed on the drone's landing gear. This ensures the stability of the probe while also accommodating the diverse operational functions of the acquisition host. Current aeromagnetic structures separate the host and probe, resulting in a complex structure and cumbersome installation. Furthermore, the existing aeromagnetic system is mounted outside the probe, which also complicates the device. Utility Model Content
