Record 1 2012-10-29

English

Subject field(s)
  • Scientific Instruments
DEF

An active instrument used to measure the altitude of an object above a fixed level.

OBS

For example, a laser altimeter can measure height from a spacecraft to an icesheet. That measurement, coupled with radial orbit knowledge, will enable determination of the topography.

OBS

There are different types of altimeters :(a) the pressure or barometric altimeter, which gives an approximate measure of altitude from a pressure measurement and an assumed standard temperature distribution;(b) the radio altimeter, which deduces altitude by electronic techniques.(c) the radar altimeter, which measures vertical distances to the surface below using radar technology.

OBS

altimeter: term standardized by NATO.

French

Domaine(s)
  • Instruments scientifiques
DEF

Instrument indiquant directement la hauteur au-dessus d'une surface de référence.

CONT

La performance de pointage du satellite a pu être évaluée grâce à une campagne dédiée de manœuvres en attitude explorant la gamme de conditions d'ensoleillement, très variables, rencontrées par le satellite : l'antenne de l'altimètre est pointée au nadir avec une erreur maximale de 0,1º. Cette valeur est de plus confirmée par les estimations fournies par les mesures de l'altimètre, et est à comparer à l'exigence de 0,2º nécessaire pour obtenir des mesures altimétriques de bonne qualité.

OBS

altimètre : terme uniformisé par le Comité d'uniformisation de la terminologie aéronautique (CUTA) - Opérations aériennes et normalisé par l'OTAN.

Subject field(s)
  • Aeroindustry
CONT

The Electronic Altimeter Set... commonly termed radar altimeter and altitude warning set(RAAWS), is used to determine absolute altitude of the aircraft above terrain or water and to provide the Pilot and Copilot with a continuous indication of absolute altitude from 0 to 5000 feet.

French
