1. Airborne magnetic survey technology: There are many types of airborne magnetic survey systems applied in middle and high mountain areas, such as installing survey systems, which are mainly realized by HC-2000K helium optical pump magnetometer, DS-II recording system, BG3.0 remote radio altimeter, GG24 dual-constellation locator and AADCII soft compensator.
2. Airborne electromagnetic exploration and measurement technology: also known as airborne electromagnetic method, it is a modern geophysical exploration technology based on aircraft. This geophysical exploration method is mainly based on the electric, magnetic and electromagnetic induction of the detection target.
