Patent abstract
A system and method for magnetic anomaly guidance is provided. Triaxial magnetometer (TM) sensors are positioned at the vertices of an arrangement with an axis of the arrangement, being defined between each pair of the vertices. The arrangement is positioned on a support such that one of the X,Y,Z magnetic sensing axes for all of the sensors defines a forward direction of movement. The sensed magnetic field's X,Y,Z components of the TM sensors are processed to generate a partial gradient contraction associated with each axis of the sensor arrangement. Relationships between the partial gradient contractions are used to generate steering control commands for use by a steering system that is coupled to the support.
