Abstract : The combination of the Global Positioning System (GPS), which can provide sufficiently accurate airplane position, speed, and direction, with the digital mapping system, which can provide terrain data on the surroundings of an air route, can produce the TF controlling commands necessary for terrain-followIng flight. A terrain-following system composed of digital mapping and GPS is a passive system. It completely eliminates the possibility of exposure due to emission of electromagnetic waves.
