Abstract

Presently contemplated satellite communication systems are seriously constrainedby satellite power supply problems which limit their transmitters to power outputs of the order of 10 w. A high power communication satellite is described which utilizes a 60 kw nuclear reactor power supply. With this satellite, spectrum space will be conserved and satellite costs may be reduced. The cost of ground stations will be reduced, particularly for small stations of the sort which would be used in less affluent countries. In addition, the higher power satellite will be capable of broadcasting television directly into home and community receivers at lower cost than can be realized by conventional means. This will make television service more readily available in those areas of the world which cannot afford television or for other reasons find it impractical at the present time.

Résumé

Les systbmes de communication par satellite couramment envisagés sont gravement gênés par les problbmes de l’alimentation électrique qui restreint la puissance à la sortie des transmetteurs à une limite de l’ordre de 10 w. Un satellite de communication à haute puissance utilisant comme source d’alimentation un réacteur nucléaire de 60 kW sera décrit. Grâce à ce satellite, la largeur du spectre utilisé sera réduite et le coût du satellite lui-même pourra être abaissé. Le coût des stations terrestres sera réduit, en particulier ce sera le cas des petites stations du genre utilisé par les pays les moins prospérés. En outre, les satellites à haute puissance pourront transmettre les signaux de la télévision directement vers les récepteurs communaux et ceux à domicile, et ils feront cela à des frais plus bas que ne le serait possible avec les moyens conventionnels. Ceci mettra la télévision à la portée des regions du monde qui ne peuvent se permettre les frais de la télévision ou qui, pour d’autres raisons, ne sont pas encore prêtes h adopter la télévision.

Абстрактный

Обсуждаемым ныне системам спутников радиосвязи свойственны значительные ограничения в связи с проблемами источников питания, лимитирующие мощность их передатчиков до величин порядка 10 ватт. Описывается высокомощный спутник, имеющий источником питания 60-киловаттовый атомный реактор. При помощи этого спутника сохраняется область спектра, а стоимость спутника удешевляется. Понижена также стоимость наземных станций, особенно станций небольших размеров такого рода, как применяемые финансово менее обеспеченными странами. Кроме того, высокомощный спутник может вести телевизионное радиовещание непосредственно в дома и общинные приемники за меньшую стоимость, чем это возможно обычным способом. Эти обстоятельства сделают телевизионное обслуживание легко доступным в тех странах мира, которым телевидение либо не по средствам, либо непрактично в настоящее время по каким-либо другим причинам.
