Kommunikationssystem und -verfahren für geosynchrone Satelliten

摘要

A geosynchronous satellite system uses crosslinks (30) between geosynchronous satellites (16) which travel along the same ground path (18) or are located within a common orbital slot (32) in order to increase traffic-carrying capacity and decrease signal delays. The geosynchronous satellites (16) can have substantial angles of inclination to provide high quality coverage within a wide range of latitudes (40,42). 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.
