ABSTRACT:
The movement of a weapon, such as a gun, about a horizontal axis and a vertical axis is measured to provide the direction of the line of aim at any instant. The elevation angle above a horizontal base is measured by a pulse counting mechanism in which the number of pulses counted is proportional to the angle. The azimuth is measured by pulse counting mechanism initiated and stopped by lights and rotating mirrors on the gun mount and at a fixed point along a base line.
