ABSTRACT:
A system for determining attitude of airborne vehicles or surface vehicles is provided with three fixed position antennas separated from each other by a predetermined calibrated distance. Each antenna is connected to a GPS receiver and the receiver outputs are coupled to a phase comparator which establishes the phase difference between the RF carrier signal of the three possible pairs of receivers. The outputs of the phase comparator are coupled to a preprogrammed dedicated processor that calculates a coordinate frame which fixes the attitude of the plurality of antennas in space. The processor then makes a comparison with a precalibrated reference attitude stored in an associated memory so that a true attitude value of roll, pitch and yaw may be calculated and employed to reposition the gyro of the moving vehicle.
