ABSTRACT:
A navigation method for independently determining direction and for determining course for aircraft with low quality gyros and an external, calibrated magnetic course sensor. The method, which functions in the event of failure of the magnetic course sensor, is based upon the concept of determining, from the magnetic course last determined prior to failure as corrected by the local declination, and the true course as determined by the quotient of the two gyro horizontal axes distorted by the gyro drift, a "synthetic magnetic course" for course support.
