The Tolles and Lawson equations were programmed on the IBM 370-65 computer. These equations predict the magnetic signals which are generated by the permanent moments, the induced moments and the eddy-current terms of an aircraft as it maneuvers in the Earth's magnetic field. By measuring the simulated figure of merit (FOM) before and after applying compensation, several types of error were studied. The algorithm is not limited by microprocessor capacity. Hystersis can cause temporal variations in the Tolles and Lawson model. It is suggested that whitening and/or adaptive techniques could be used to minimize such variations.
