 Guidance and Control System (Contd)

The fourth stage which includes the payload package does not have an active guidance and control system. It receives the proper spatial orientation from the control exerted by the first three stages after which it is spin stabilized by a combination of two or four 40 pound-sec impulse spin motors, as required, which are mounted tangentially in the skirt at the base of the fourth stage. Scout A, B, and C guidance systems are identical.

Scout A, B, C

The following figures and charts portray information for Scout B only. Scout A will be dropped and Scout B will take its place in 1962. Scout C consists of Scout B plus a fifth stage.
