Geomagnetic field direction measuring system

Abstract

An arrangement for measuring the direction of the geomagnetic field {right arrow over (B)}E, in the proximity of a magnetic jamming device with a magnetic field direction variable as a function of time, which is distinguished by the fact that at least two magnetic field measuring devices are provided, each of which measures all three vector components of the total magnetic field ({right arrow over (B)}1,{right arrow over (B)}2), the magnetic field measuring devices have a position, ({right arrow over (r)}0,{right arrow over (r)}1,{right arrow over (r)}2) which is invariable as a function of time and is fixed relative to one another and relative to the jamming device, and the measured values can be called up synchronously and can be evaluated according to {right arrow over (B)}E=({right arrow over (B)}1+{right arrow over (B)}2)/2+P·({right arrow over (B)}1−{right arrow over (B)}2), P({right arrow over (r)}0,{right arrow over (r)}1,{right arrow over (r)}2) describing the geometric position of the magnetic field measuring devices relative to one another and relative to the jamming device.
