Abstract

See full text

A method and an electronic device for determining the direction of a magnetic field, in which a mobile electronic compass device is used to measure three field vectors of the magnetic field the desired number of times. From each measurement, a data point (p1-p6) is formed in a three-dimensional co-ordinate system, for which measured data points a common reference point (C) is calculated. The location of the device is determined relative to the reference point in said co-ordinate system and the co-ordinates of the reference point obtained are compared to the co-ordinates of at least one previous reference point, and the co-ordinate values of the reference point are calibrated, after which the direction of the magnetic field is indicated with the aid of the reference point.
