Abstract:	EARTH SATELLITES have a property not shared by other man-made objects. Their great altitude enables them to “see” a very large region of the earth, and therefore they can serve as relay points for line-of-sight. radio propagation between widely separated points on the earth. Except for their unusual altitude, there is not,hing very special about earth satellites. The radio equipment they carry to perform their functions has performance characteristics like radio equipment used for similar purposes in earth-based applications. Satellite motions can be tracked and their locations determined so accurately that they may be used as reference points for determining the positions of craft on the earth. The techniques for using them as references for position fixing are all familiar.
