Abstract
Способ построения глобальной спутниковой системы ретрансляции информации между низкоорбитальными космическими аппаратами и наземными приемопередающими станциями с использованием спутников-ретрансляторов на геостационарной орбите, при котором связь спутника-ретранслятора с низкоорбитальными космическими аппаратами осуществляют в пределах пространства, ограниченного с внешней стороны круговым прямым конусом с вершиной в точке расположения спутника-ретранслятора и с осью, проходящей через центр Земли и точку расположения спутника-ретранслятора, при этом угол при вершине конуса выбирают не менее 2arcsin(RНКАмакс/RГСО), где RНКАмакс - максимальный радиус орбиты низкоорбитального космического аппарата, RГСО - радиус геостационарной орбиты спутника-ретранслятора, наземные приемопередающие станции располагают в зоне радиовидимости спутников-ретрансляторов, отличающийся тем, что орбитальное разнесение спутников-ретрансляторов выбирают в пределах от 2[arcsin(RЗ/RГСО)+arcsin(RЗ/RНКАмин)] до 360°-2[arcsin(RЗ/RГСО)+arcsin(RЗ/RНКАмин)], где RЗ - радиус Земли с учетом высоты атмосферного слоя, RНКАмин - минимальный радиус орбиты низкоорбитального космического аппарата, а связь низкоорбитального космического аппарата со спутником-ретранслятором осуществляют в пределах угла раскрыва ±Θ=180°-arcsin[RЗ/(RЗ+Нмакс)], где Нмакс - максимальная высота полета НКА, ориентированного в направлении от центра Земли и отсчитываемого при всех значениях азимута относительно прямой линии, соединяющей центр Земли с точкой расположения низкоорбитального космического аппарата. A method of constructing a global satellite information relay system between low-orbit spacecraft and ground-based transceiver stations using satellite transponders in a geostationary orbit, in which the communication of the relay satellite with low-orbit spacecraft is carried out within a space bounded from the outside by a circular straight cone with a vertex at a point the location of the repeater satellite and with the axis passing through the center of the earth and the satellite location point a-repeater, with the angle at the apex of the cone choosing at least 2arcsin (RNKAmax / RGSO), where RNKAmax is the maximum radius of the orbit of the low-orbit spacecraft, RГСО is the radius of the geostationary orbit of the relay satellite, ground-based transceiver stations are located in the radio-visibility zone of the satellite-relay characterized in that the orbital diversity of the satellite transponders is selected in the range of 2 [arcsin (RЗ / RГСО) + 360 ° -2 [arcsin (РЗ / RГСО) + arcsin (РЗ / RГСО)], where RЗ is the radius of the Earth, taking into account the height of the atmospheric layer, RNKAmin - the minimum radius of the orbit of the low-orbit spacecraft, and the communication of the low-orbit spacecraft with the satellite-relay is carried out within the aperture angle ± Θ = 180 ° -arcsin [RЗ / (RЗ + Нмакс)], where Nmax is the maximum altitude of the spacecraft oriented in the direction from the center of the Earth and measured at all azimuths relative to a straight line connecting the center of the Earth to the point of location of the low-orbit spacecraft.
