In this paper, we discuss the beginnings of this effort, drawing primarily on the experience of one of the past attitude control system (ACS) groups at Goddard (what was formerly known as Code 712, the Guidance, Navigation, and Control (GN & C) Branch). We discuss the analysis and design methods and criteria used, including guidelines for linear and nonlinear analysis, as well as the use of low- and high-fidelity simulation for system design and verification of performance. Descriptions of typical ACS sensor and actuator hardware are shown, and typical sensor/actuator suites for a variety of mission types detailed. A description of the software and hardware test effort are given, along with an attempt to make some qualitative estimates on how much effort is involved. The spacecraft and GN&C subsystem review cycles are discussed, giving an outline of what design reviews are typically held and what information should be presented at each stage. Finally, we point out some of the lessons learned at Goddard.
