ABSTRACT:
An aircraft navigation system uses an infra-red scanner to provide an image of the ground, and a laser doppler system to measure the speed of the aircraft relative to the ground. The apparent movement relative to the aircraft of features in the image is extrapolated to find the point in the image at which this movement converges. This point corresponds to the direction in which the aircraft is moving. Knowing the original position, the direction and motion of the aircraft, its new position can be calculated.
