Abstract
A remote reading magnetic compass operative with only two electrical connections for both power and data purposes. The compass includes a disc which is photoelectrically sensed to provide output signals representative of compass heading and is supported by a gimbal assembly including pivots which serve as electrical terminals by which energizing power is supplied to the compass electronics and by which data is read out from the compass.
