Abstract
This invention discloses a method for measuring the rate of angular displacement, of a traveling object, using magnetic field sensing, said method comprising: measuring magnetic field intensity and/or changes in said magnetic field intensity, projected onto a magnetic field sensor coupled to said traveling object, each measurement being per orthogonal rotation axis to provide a magnetic field intensity value per axis and/or a change in magnetic field intensity per axis, as said object's orientation changes with time; determining, number of peaks, present in a measurement sample comprising a set of said measurements, of time duration; and computing said rate of angular displacement, for said traveling object, as a function of said determined number of peaks and said time duration.
