Cesium Optical Pump Uav Aeromagnetic Magnetometer System

Aeromagnetic survey is a geophysical method. For this method, the airborne magnetometer and its auxiliary equipment are loaded on an aircraft. The purpose is to measure the intensity or gradient of the geomagnetic field in accordance with the preset line and altitude over the measuring area. It has high measurement efficiency compared with surface magnetic survey. And it is not restricted by water, forest, swamp, desert and mountain. At the same time, the flight is carried out at a certain height from the surface. Hence, the influence of surface magnetic inhomogeneity is weakened. And the magnetic field characteristics of the deep geological body can be reflected more clearly.

The basic cesium optical pump magnetometer can be mounted on multiple types of manned and unmanned aerial vehicles . So it can complete the aeromagnetic measurement tasks. Such as squirrel manned helicopter, power delta wing, airship, small-load directly connected multi-rotor, large-load towed multi-rotor, fixed wing, etc.

The characteristics of aeromagnetic survey are that the measurement speed is fast and it can overcome various complicated terrain. So its contribution in minerals, hydrology, geological disaster, military geology and other aspects outstanding. The aeromagnetic operation of UAV is safer than that of manned aircraft. Because it can be deployed quickly. Uav aeromagnetic can achieve low/ultra-low altitude operation under large scale conditions. Compared with the ground magnetic survey, it can not only eliminate the influence of surface disturbances. But also it can collect the ground magnetic field data in high speed, high efficiency and high precision. Therefore, it provides a new and very effective low-cost means for the rapid evaluation of mineral geological survey.
