Record 3 2003-11-26

English

Subject field(s)
  • Satellite Telecommunications
  • Orbital Stations
CONT

High data rate intersatellite communications will be needed in applications such as short range links between clusters of satellites in one or adjacent orbital slots, medium range links forming a network in LEO (Low Earth Orbit) and MEO (Medium Earth Orbit) constellations, and longer links between GEO (Geostationary Orbit) satellites. This requires optical intersatellite links or satellite to ground communications links with digital data transfer at 10 Gbps at ranges of 10 000 kilometres.

OBS

Optical intersatellite links offer higher data rates than microwave alternatives. There is no requirement for spectrum approval and interference threats are minimal with laser communications.

Key term(s)
  • optical inter satellite link

French

Domaine(s)
  • Télécommunications par satellite
  • Stations orbitales
OBS

Les liaisons optiques intersatellites offrent un débit binaire plus élevé que les liaisons hyperfréquences, aucune approbation de spectre n'est nécessaire et les risques de brouillage sont minimes.

Record 7 1985-01-24

English

Subject field(s)
  • Telecommunications Transmission
CONT

... a Maritime Communications Subsystem(MCS) [will be] on board the INTELSAT V spacecraft. The MCS is an active repeater with two transponders used to relay microwave signals from ships at L-band and retransmit them to shore at C-band; the other transponder receives signals from shore at C-band and retransmits them to ships at L-band.(INTELSAT BG-35-45E, Nov. 1978, p. 1)

French

Domaine(s)
  • Transmission (Télécommunications)
CONT

(...) un sous-ensemble de télécommunications maritimes (STM) [sera] à bord du satellite INTELSAT V. Le STM est un système actif à deux répéteurs qui sont utilisés pour relayer des signaux hyperfréquences entre des stations côtières et des stations de navire en mer. Un répéteur reçoit les signaux en provenance des navires dans la bande L et ces signaux sont réémis vers la station côtière dans la bande C; l'autre répéteur reçoit les signaux en provenance de la station côtière dans la bande C et ces signaux sont réémis vers les stations de navire dans la bande L.
