Abstract
The magnetometric method is used among other things on mobile platforms (planes, helicopters) in military systems and in geological research. Optically-pumped and SQUID magnetometers are used in magnetic systems on airplanes. To be able to attain the sensitivity of modern magnetometers in flight, it is important that maneuver-related magnetic interference effects be minimized. The mathematical model of an aircraft as a source of magnetic interferences has been known since the early 1950's. Modern computer programs analyzing electromagnetic fields allow us to carry out the analysis of individual sources of aircraft interference. The results of numerical analysis of magnetic interferences of an aircraft model caused by permanent and induced magnetization and by eddy currents, are presented in this paper. The possibility of a significant reduction in an aircraft's magnetic interference by collecting data from more than four cardinal magnetic directions while in flight, is the most important conclusion of these computer simulations.
