Abstract : The patent relates to a magnetic compass of the flux valve type, capable of proper indication in all attitudes within the earth's magnetic field. When the compass is mounted in a vehicle, it compensates for vehicle orientation and motion, and deviation or installation error may also be compensated for. The compass is provided with four compensating poles arranged 120 degrees spherically apart from each other radiating from a center. Each set of three poles of the four operates much like a conventional flux valve, but vehicle pitch and roll are compensated for by energizing the compass system with synchro-signals indicative of the vehicle's attitude. Alternatively, the flux valve compass system will act as a compass and attitude indicator showing azimuth, pitch, and roll, when these signals are not supplied.
