Title
  • Helicopter-borne Magnetics (HMG)
  • Hubschrauber-Magnetik (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 helicopter-borne magnetic (HMG) measuring system is a cesium magnetometer, which is installed into the HEM bird about 40 m beneath the helicopter. The total intensity of the Earth’s magnetic field is recorded. After reduction of the Earth’s main field and the diurnal variations, the resulting anomalies of the Earth’s magnetic field are displayed.
  • Der BGR-Messhubschrauber (Sikorsky S-76B) wird zur aerogeophysikalischen Erkundung des Erduntergrundes eingesetzt. Das Standardmesssystem umfasst die Methoden Elektromagnetik, Magnetik und Radiometrie. Das passive Messsystem der Hubschrauber-Magnetik (HMG) ist ein Cäsium-Magnetometer, das sich in der HEM-Flugsonde etwa 40 m unterhalb des Hubschraubers befindet. Gemessen wird die Totalintensität des erdmagnetischen Feldes. Nach Abzug des erdmagnetischen Hauptfeldes und der Tagesvariationen werden als Ergebnis die Anomalien des erdmagnetischen Feldes dargestellt.
