Record 1 2007-01-31

English

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

[An antenna] equipped with distributed transmit/receive modules which provide distinct transmit and receive beams.

CONT

The most significant difference between RADARSAT-2 and RADARSAT-1 payload technology is that RADARSAT-2 uses a fully-active phased array antenna, rather than the passive slotted waveguide antenna used by RADARSAT-1. Fully-active phased arrays offer a number of very significant benefits over passive antenna, but they also add great complexity.... The phased array is made up of 512 individual radiating elements, organized into 16 columns(picture below shows a single column) along the 15-metre antenna length, each with 32 rows across the 1. 5-metre width. The phase shifters and amplitude control are built into the Transmit/Receive(T/R) modules, which feed the radiating elements. Each column has a computer that controls the 32 T/R module settings and these 16 computers are all linked to another computer(in the spacecraft bus) that orchestrates the overall antenna behaviour.

OBS

active array antenna: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Record 3 2003-01-22

English

Subject field(s)
  • Scientific Research Facilities
  • Research Experiments in Space
CONT

The Technology Exposure Facility(TEF), currently under study by ESA [European Space Agency], is a way of accommodating a wide range of research and development investigations and offering a controlled exposure to the space station environment.... The principal new feature for an exposed payload facility is the presence of a single, multi-purpose robotic servicing capability.... Together with the robotics, the modular architecture of the facility allows on orbit reconfiguration and, more significantly, a "black box" approach to the accommodation of individual payloads.

Record 5 2001-07-18

English

Subject field(s)
  • Orbital Stations
  • Research Experiments in Space
CONT

The Commercial Protein Crystal Growth-H experiment consists of 1, 008 individual experiments contained in a High-Density Protein Crystal Growth Assembly. This assembly is then stored in the Commercial Refrigerator Incubator Module(CRIM) at 22 degrees Celsius(72 degrees Fahrenheit). The Space Station crew will install the CRIM into a locker in the Space Station EXPRESS Rack 4 in the U. S. Lab, activate the crystal growth experiments and conduct daily status checks. These daily checks consist of checking temperature readings and cleaning the air filter. When the payload is scheduled to return to Earth, the crew will deactivate the experiments and return the module.

OBS

commercial refrigerator incubator module; CRIM: term and abbreviation officially approved by the International Space Station official approval Group (ISSOAG).

French

Domaine(s)
  • Stations orbitales
  • Travaux de recherche dans l'espace
OBS

module d'incubation et de réfrigération commercial; CRIM : terme et abréviation uniformisés par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).
