Abstract:

Solutions are obtained to the problem of providing continual surveillance of latitudinally bounded zones of the globe by means of a particular family of satellite networks. Each network considered consists of satellites equally divided among and uniformly distributed around circular orbits of common altitude the orbit planes are equally inclined with respect to the equator and are uniformly arranged about the polar axis. It is shown that by properly choosing the number and inclination of the orbit planes, the required coverage may be obtained furthermore, a rational procedure is presented for minimizing the total number of satellites required at a given altitude. Results obtained by this optimization technique are displayed graphically for several representative cases of coverage requirements. Author
