Device for measuring the magnetic field of the earth as a navigational aid

摘要

Device for measuring the electromagnetic field as a navigational aid for the driver of a motor vehicle, particularly for orientation in a city, in which three magnetic sensors (1, 2, 3), which are located in axes (X, Y, Z) arranged orthogonally with respect to one another and which output an electrical signal are provided and a flux concentrator (4, 5, 6) arranged in one of the axes is allocated to each sensor (Figure 1).
