Abstract
This method makes it possible to carry out the auto-calibration of the electromagnetic coils of an apparatus such as an atomic clock, a magnetometer or a gyroscope by injecting successive currents into the coils and measuring the magnetic fields induced in order to calculate the transfer coefficients (field/current) of each of the coils and the real angles that they form with very great precision.
