Abstract : The patent describes a guidance system which employs three total field magnetometer sensors located in a plane and spaced equiangularly about the axis of locomotion. Circuitry is disclosed to combine the outputs of adjacent sensors for operation of a control element positioned at right angles to the plane of the sensors, so as to steer a desired course with respect to a magnetic anomaly in an ambient, i.e., the earth's, magnetic field. Circuitry is also disclosed which is effective to resolve the ambiguity of steering toward or away from the anomaly and, thereby, insure the desired course of steerage.
