Orbital Mechanics and Military Satellites
Since the beginning of the space age in 1957, both superpowers have launched into earth orbit a great number and variety of military satellites. In order to understand better their functioning, capabilities and the constraints to which they are subjected, it is useful to have some knowledge of orbital mechanics, that is of the laws of motion in space and of their applications to various types of artificial satellites designed to carry out some specific mission of military interest. Motion in space occurs according to rules that are strikingly different with respect to those we are used to on the earth’s surface, and the purpose of this chapter is thus to acquaint the reader with these rules in a simple and non-technical way.
