Abstract
A geosynchronous satellite system (,) uses crosslinks (,) between geosynchronous satellites (,) which travel along the same ground path (,) or are located within a common orbital slot (,) in order to increase traffic-carrying capacity and decrease signal delays. The geosynchronous satellites (,) can have substantial angles of inclination to provide high quality coverage within a wide range of latitudes (,). In addition, the orbits can be elliptical, resulting in concentrated network capacity in either the northern or southern hemisphere. For co-positioned satellites (,), orbit perturbations are introduced in order to eliminate crosslink blockage caused by intervening satellites (,). Methods for deploying and operating the geosynchronous satellite system enable network capacity to be modified (,) and routing (,), crosslinks (,), and handoffs (,) to be controlled.
