Apollo Guidance Navigation and Control: Design Survey of the Apollo Inertial Subsytem

The Design Survey of the Apollo Inertial Subsystem was funded by NASA under Contract NAS-l2-642. This contract was administered by the NASA Electronics Research Center of Cambridge Massachusetts. The purpose of this document is to record the history of the Apollo Inertial Subsystem design and development (CSM and LM) in order to provide a source document for subsequent design criteria monographs. The record provided by this document covers the de sign development and testing of an inertial subsystflm intended for manned spaceflight beyond earth orbits. In addition it highlights the experience and knowledge accumulated by this portion of the Apollo program. Finally technical and program-oriented recommendations have evolved naturally from the experience documented and such recommendations are given as an important part of this Design Survey.
