1. A motion characterization system, comprising:

  • two antennas, mounted to a rigid body, to receive navigation signals;

    a collection of motion sensing devices, including rate gyroscopes providing poorer than two degrees per hour accuracy, mounted on the rigid body to provide electrical signals providing motion information; and

    a processor electrically coupled to process electrical signals from the antennas and the motion sensing devices to provide an attitude measurement of the rigid body under arbitrary motion conditions.
