heliostat

(hee -lee-ŏ-stat) A coelostat mirror mounted on a synchronously controlled drive mechanism so that it may reflect sunlight in a fixed direction as the Sun moves across the sky. Together with additional optical elements it is a basic component of most solar telescopes.

[′hē·lē·ə‚stat]
(engineering)
A clock-driven instrument mounting which automatically and continuously points in the direction of the sun; it is used with a pyrheliometer when continuous direct solar radiation measurements are required.
