FIELD: radio engineering. ^ SUBSTANCE: invention relates to radio engineering, namely to relay-satellites (RS) used on high elliptic orbits (HEO). Proposed method uses geosynchronous satellites with longitudes ascending nodes spaced apart through 120 and RS connected via at least, one feeder line with central station. Data line is switched over from Earth Users from RS leaving the their service zone to RS entering aforesaid zone. Proposed method differs from known versions in that every RS is furnished with multi-beam antenna with maximum angle of its beams deviation from the axis passing through RS location and Earth center restricted by angle =arcsin [Rsv/(R3+Hop)], where Rsv is the radius of sphere of possible locations of space Users, R3 is the Earth radius, Hop is the RS orbit perigee. Central group of beams is isolated from those formed by RS covering the Users service zone, as well as peripheral group covering the remaining zone restricted by angle . Via previously mentioned zones, data exchange with space Users is performed. Note that RS staying outside service zone effects data exchange with space objects through central and peripheral groups of multi-beam antenna beams. Inter-satellite radio lines are used to communicate RS with two other RSs staying outside above specified service zone. ^ EFFECT: maximum period of RS operation. ^ 4 dwg |
