Raw Data on Helicopter-borne Magnetics (HMG)
Description
The BGR helicopter (Sikorsky S-76B) is used for airborne geophysical surveying of the Earth’s subsurface. The standard equipment comprises the methods electromagnetics, magnetics and radiometrics. The passive magnetic (HMG) system consists of two Cesium magnetometers, which are located in the HEM flying tube (bird) about 40 m beneath the helicopter as well as in a base station on ground. Reduction of the Earth’s main field and the diurnal variations yields to the resulting anomalies of the Earth’s magnetic field.
