Record 3 2010-10-04

English

Subject field(s)
  • Theoretical Astronomy
CONT

If altitudes at sea could be measured with respect to the observer's vertical, the point directly over his head, which on land might be determined with an accurate plumb-bob or spirit-level, high accuracy could be obtained. Unfortunately, at sea the observer in a moving vessel has to measure altitudes with respect to the horizon.

French

Domaine(s)
  • Astronomie théorique
CONT

L'angle d’altitude est une des deux coordonnées locales(l'autre est l'angle d’azimut) qui permet de localiser les étoiles depuis l'altitude 0°, correspondant au niveau de l'horizon, jusqu'à l'altitude 90°, correspondant à la verticale de l'observateur c'est-à-dire au point du ciel situé au-dessus de sa tête, que l'on nomme le «zénith».

DEF

The point on the celestial sphere directly below an observer and diametrically opposite the zenith.

Orientation is described using the terms "forward", "aft", "port", "starboard", "zenith", and "nadir". There is a diagram of the ISS [International Space Station] in the instructions that depicts these axes. [Generally, the Russian, modules are aft, and the European modules are/will be forward; "nadir" and "zenith"are, of course, "down" and "up," respectively.]
