Abstract

A system and device for detecting yaw and changes in pitch angle for use with navigational and positional devices. The system and device include a multi-axis magnetic field sensing device and a controller. Preferably, the magnetic field sensing device is a multi-axis magnetic compass that is capable of sensing variations in pitch and yaw. The controller is adapted to process yaw and pitch rotational data to determine a positive or a negative change in pitch.
