Abstract

The position of a carrier from a navigational reference generates X,Y coordinate navigation signals which are scaled as distance along a TV line of a TV display and a line number in the frame of the TV picture. A continual updated track of a moving vehicle is therefore displayed on a TV monitor, and if a video disc is used, can be recalled from the non-volatile memory for later replay.
