Abstract
An electronic circuit includes an electronic compass having e-compass sensors mounted on different axes and operable to supply e-compass sensor data, memory circuitry, and an electronic processor coupled to said e-compass sensors and to said memory circuitry, said electronic processor operable to execute an electronic ellipse-fitting procedure responsive to the e-compass sensor data to generate at least one signal related to an ellipse tilt angle, and store the at least one signal in said memory circuitry as a tilt calibration parameter for the e-compass. Processes for calibrating an e-compass, as well as electronic circuits and processes for correcting measured heading, and processes of manufacture are also disclosed.
