MODULE CONTROL COMPUTER [3 records]

Record 1 2015-10-21

English

Subject field(s)
  • Electric Power Distribution
DEF

That portion of an electric system used to deliver electric energy from points on the transmission or bulk power system to the consumers.

CONT

An electrical engineer is someone who designs and implements a fibre-optic transmission module for a high-speed telephone network; develops and programs a computer control system for an automated production line; plans and supervises the electrical distribution network between a remote electrical generating station and the end-users separated by hundreds of kilometres.

French

Domaine(s)
  • Distribution électrique
DEF

Réseau servant à la distribution de l'énergie électrique à l'intérieur d'une région délimitée.

CONT

L'ampleur des dégâts nous force à nous demander si les choix qui ont été faits par le passé, celui de quadriller la région montréalaise d'un réseau de distribution d'électricité reposant sur l'approche traditionnelle des poteaux et des fils aériens, ont été les bons.

Spanish

Campo(s) temático(s)
  • Distribución de energía eléctrica
DEF

Red que sirve para la distribución de energía en el interior de una región o zona determinada.

CONT

En las distintas fases de la distribución, adémas de los transformadores, se usan numerosos aparatos de mando, regulación y protección de la red distribuidora y de las instalaciones de los clientes [...]

Record 2 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).

French

Domaine(s)
  • Télécommunications par satellite
  • Radar, radioguidage et radiogoniométrie
  • Engins spatiaux
DEF

Antenne composée de plusieurs éléments rayonnants, installée à bord d'un satellite et destinée à la transmission et à la réception des données.

CONT

Le radar à synthèse d'ouverture [de RADARSAT-2] comprend un système électronique sophistiqué qui alimente une antenne active à réseau d'éléments en phase qui consiste en 512 modules de transmission-réception (TRM) avec des réseaux de distribution de puissance et fréquences radio.

OBS

antenne-réseau active : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Record 3 2003-12-08

English

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

[The] EMCS consists of a gas tight incubator containing two centrifuges with space for 4 Experiment Containers on each rotor; also the life support and water supply system, the illumination and the observation system are located on the rotors. External to the incubator are the Standard Payload Computer(SPLC), the gas supply module and the thermal control system. The flight unit is accommodated in an EXPRESS Rack on the International Space Station. Ground controls will be performed in dedicated Experiment Reference Models, one located in Europe, the other at NASA Ames Research Center.

CONT

[The] EMCS is dedicated to experiments on plants, especially multi-generation (seed-to-seed) experiments and studies on gravity effects on early development and growth, on signal perception and transduction in plant tropisms. Experiments with insects or amphibia as well as studies with cell and tissue cultures are also foreseen in EMCS.

OBS

European modular cultivation system; EMCS: 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
CONT

[Le] European Modular Cultivation System (EMCS) [est] destiné à l'étude biologique des plantes (croissance, développement, influence de la microgravité).

OBS

module européen d'étude biologique des plantes; EMCS : terme et abréviation uniformisés par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).
