ABSTRACT
As we have seen in Chapter 8, communication with a satellite is extremely important for tracking, telemetry and control as well as its use for its intended purpose. This chapter deals with the correlative matter of satellite orbits before turning to two particular uses of space; direct broadcasting, which happens now, and solar power beamed from space, which may happen. Apart from Earth orbits there are, of course, trajectories that take space objects out of Earth orbit. These are used by science probes, and some legal rules have relevance for them.1 However, this chapter is concerned with Earth orbits and aspects of their use.
