Abstract
The invention relates to a method for determining a heading, in which a magnetic field is measured by at least one magnetometer and a magnetic heading is determined from said measurement and in which calculation means implement a processing calculating, for each measurement of magnetic heading, a value for characterising the heading thereby determined, characterised in that said characterisation value is a monotone function of a norm of the measured magnetic field gradient, said value being used in the determination of the heading.
