Subject field(s)
  • Satellite Telecommunications
  • Radar, Radio Guidance and Goniometry
CONT

Two approaches exist for contouring the radiation pattern of a satellite reflector antenna : use of a conventional offset parabolic reflector system combined with a multi-element feed array, rather than a single element; retaining the single feed element but modifying, or shaping, the profile of the reflector(or reflectors).

Record 2 2011-03-14

English

Subject field(s)
  • Spacecraft
CONT

A multibeam, spherical-reflector satellite antenna for the 20-and 30-GHz bands. A multibeam antenna for satellite communication affords reuse of frequency allocations and flexibility in traffic routing. A multibeam satellite antenna is described that employs a spheroidal reflector in a compact periscope design. The aperture is 1. 5 meters in diameter radiating six beams in the 20-and 30-GHz satellite frequency bands. Electrical measurements indicate that this antenna is suitable for multibeam satellite use.

Record 3 2007-08-21

English

Subject field(s)
  • Scientific Instruments
  • Remote Sensing
CONT

The Laser Retro Reflector(LRR), mounted on the owner's side of the payload module, reflects the laser beams directed to the satellite back to the tracking station. The two-way travel time is a measure for the distance between the satellite and the tracking station. Tracking information from various sites throughout the world provides the essential information for computing the ERS [European Remote Sensing Satellite] orbits.

French

Domaine(s)
  • Instruments scientifiques
  • Télédétection
CONT

[Le] réflecteur laser LRR (Laser Retro-Reflector) [est un] instrument passif [qui] permet de déterminer précisément l'orbite du satellite grâce à des tirs laser à partir de stations terrestres. (ESA, réalisé par Alcatel Space à Cannes)
