1. An inertial measurement system for determining the attitude and rate of change of attitude of a vehicle, about an IMU directional axis of a first reference system:

  • a second reference system comprising a global positioning system having dual receivers for deriving two coordinate position and attitude inputs from satellite reference signals from a pair of antennas, said antennas being mounted on the vehicle along a directional axis of the vehicle, said directional axis being non-coincidental with respect to said IMU directional axis;

    said second reference system providing an independent measurement of the performance of said first reference system for detecting a failure of said first reference system.
