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

European Payload. [The core of the] ACES (Atomic Clock Ensemble in Space) [project] is a laser-cooled caesium atomic clock (Pharao), which exploits the microgravity conditions onboard the Space Station ... Pharao will improve clock frequency stability and accuracy by a factor of 100 compared with the best measurements currently achievable on Earth, opening up new opportunities in various fields of fundamental research and applications. This ultra-precise measurement of time will allow relativistic measurements and tests, applications in atmospheric physics and geodesy, navigation and advanced telecommunications.

OBS

Pharao; laser-cooled caesium atomic clock: terms officially approved by the International Space Station official approval Group (ISSOAG).

CONT

Pour tester la Relativité générale dans le système solaire, le CNES [Centre national d’études spatiales] développera d’abord de nouveaux outils de métrologie temps-fréquence(tels que ceux du projet d’horloge atomique à atomes refroidis PHARAO, installé en 2005 sur la station spatiale et dont l'exactitude et la stabilité atteindront 10-16 par jour), ainsi que des techniques de transfert de temps ultra précis.

OBS

Pharao; horloge atomique à atomes refroidis : termes uniformisés par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).
