Abstract:

The injection of a satellite into a circular orbit 5000 NM high serves as example for the discussion of the problems which result of the design of the third stage power-plant having a long combustion time and low thrust for guidance. Design and operating mode of the control system for pre-set guidance and command guidance are described. Arising difficulties are discussed by means of the solution of the equations of motion of the control system incorporating, in addition to pre-set guidance, a command guidance on analog and digital computer.
