The paper describes the mechanics of satellite orbits and explains why certain operations are suited to particular orbits. It discusses the requirements for launching satellites into space and maneuvering them once in space. It considers the consequences of the space environment for basing certain military missions there. Finally, it describes the elements of a satellite system and assesses the vulnerability of these components to various types of interference or destruction. It also includes an analysis of technical measures for reducing satellite vulnerability.
