An instrument consisting of a mirror moved by clockwork, by which a sunbeam is made apparently stationary, by being steadily directed to one spot during the whole of its diurnal period; also, a geodetic heliotrope.
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.
a mechanical device which turns to point continuously at the sun
a motorised mirror that counteracts the earth's rotation by spinning at half the rate the earth is spinning around the sun in the opposite direction
a two axis solar tracking mirror that reflects sunlight onto a fixed receiver
A device that tracks the movement of the sun; used to orient solar concentrating systems.
A mirror that reflects solar rays onto a central receiver. A heliostat automatically adjusts its position to track daily or seasonal changes in the sun's position. The arrangement of heliostats around a central receiver is also called a solar collector field.
A device used to monitor solar activity. The heliostat consists of two mirrors, one of which moves electrically to track the sun's motion. A beam of sunlight from the heliostat passes through a refracting telescope and a large image of the sun is project onto a screen. We have a heliostat designed and built by the Byers Company.
A Heliostat is a device that tracks the movement of the sun. It is typically used to orient a mirror, throughout the day, to reflect sunlight in a consistent direction. When coupled together in sufficient quantities, the reflected sunlight from the heliostats can generate an enormous amount of heat if all are oriented towards the same target.
