Abstract: A terrain vehicle contour measuring and storage system is disclosed, for ulating a carrier vehicle, which senses and follows a model board surface by means of first, second, third, and fourth terrain probes, with each of the terrain probes providing an analog signal which is proportional to the elevation sensed by the terrain probe. The terrain probes are connected in a unique combination with a pair of shift registers, with each shift register having a plurality of adjacent storage bits, and a computer. The computer, upon sampling the analog signals obtained from the terrain probes, calculates the pitch, roll, and heave of the carrier vehicle body being simulated by the terrain vehicle contour measuring and storage system.
