Abstract
A high performance solid-state heading sensor for underwater towed arrays is taught that combines high quality MEMS sensor components with data processing filters to resolve performance limitations present in prior art heading sensors. The heading sensor employs rate gyroscopes, accelerometers, magnetometers and a customized Kalman filter formulation implemented on a micro-controller to improve performance in determining the roll, pitch and heading of a towed array.
