Radio Control of Missiles and Space Vehicles. Part IV. Features of the Radio Control of Ballistic Missiles and Space Vehicles,
Abstract
Radio-engineering systems for controlling the motion of space vehicles (SV) and intercontinental ballistic missiles (ICBM), based on general radio-control principles, have important features as compared with control systems of short-range rockets. The latter are continuously controlled for the entire duration or almost the entire duration of their flight from launching to target (although the control commands can also be generated discretely with a certain gap factor). Space vehicles are controlled for comparatively short time intervals which comprise a negligible portion of their total flight time. Therefore, such control may be called discrete, although commands can constantly be generated during these short intervals. This basic difference in control methods (continuous and discrete control) is stipulated by various control-system problems. The task of controlling short-range rockets is to destroy manuevering objects whose law of motion cannot be predicted. Hence, there also arises the problem of continuously controlling the rocket up to the time it encounters its target. A system for controlling a space vehicle or ICBM should make certain that the vehicle reaches a given point (area) of space at a given time with a given accuracy. Here, the vehicle should execute a motion along a precalculated fixed trajectory. Precisely this makes it possible to discretely control the vehicle, at least along certain segments of its trajectory.
