Guidance and Control for Atmospheric Entry

Abstract

Previous chapters in this book provide the foundation of physics and technology required for the development of spacecraft systems for atmospheric entry. Hardware systems design involves assembling the technological blocks in such a way as to satisfy mission requirements while at the same time not violating critical constraints on size, weight, reliability, power, environmental provisions, and performance. It is clear that guidance and control are important elements in any recentry system, whether it be manned or unmanned. This chapter examines the concepts and hardware for guidance and control of the Mercury, Gemini, and Apollo spacecraft. The reentry technology for manned spacecraft systems has matured very greatly in the 1960’s.
