On-Orbit Propulsion and Methods of Momentum Management for the International Space Station

This paper describes the concept of operations and architecture of the International Space Station (ISS) on-orbit propulsion system and details the methods used for momentum management. The intent of this paper describes state of the art for the complex ISS currently being built in low Earth orbit. Construction and operation of the ISS propulsion systems are the result of international collaboration with the ISS partners although principle heritage lies with the United States and Russia. While design details are beyond the scope of this work, this paper will provide the reader with an understanding of how the ISS elements (and partners) work together to provide altitude and attitude control for the on-orbit ISS from hardware on-orbit to ground operations.
