Abstract:

A study has been made of circular orbit patterns which ensure that every point on the earths surface can always see at least one satellite or two satellites for double coverage above some minimum elevation angle. It is shown that five or six high altitude satellites can provide single coverage, and seven or nine satellites double coverage, at elevation angles which represent a significant improvement over previously published values and a generalized approach to such coverage assessments is presented.
