Abstract
An apparatus for measuring the location and attitude, as well as, locational and attitudinal changes of a rigid body in space has a transmission system which is composed of at least three current-permeated elements arranged at right angles relative to one another and supplied with different operating frequencies by an alternating current generator. The alternating magnetic field thereby generated are received by a plurality of magnetic field sensors arranged perpendicular to one another. The magnetic field sensors are attached to the rigid body. An evaluation electronic instrument separately evaluates the signals obtained from the three different alternative fields and converts them into quantities corresponding to the position to at least one point of the body. The magnetic field sensors are preferably magnetic coils which are arranged perpendicular to one another on a coil body of non-ferromagnetic material.
