Abstract:
An arrangement for measuring a direction of a geomagnetic field {right arrow over (B)}E in a proximity of a magnetic jamming device with a magnetic field direction variable as a function of time, wherein at least two magnetic field measuring devices are provided, each of which is adapted to measure all three vector components of a total magnetic field {right arrow over (B)}1,{right arrow over (B)}2, the magnetic field measuring devices having fixed positions {right arrow over (r)}0,{right arrow over (r)}1,{right arrow over (r)}2 which are invariable as a function of time relative to one another and relative to the magnetic jamming device, and wherein 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)/2PÂ·({right arrow over (B)}1âˆ’{right arrow over (B)}2), P({right arrow over (r)}0,{right arrow over (r)}1,{right arrow over (r)}2) describing a geometric position of the magnetic field measuring devices relative to one another and relative to the magnetic jamming device.
