All about GTC

How will it work?

The mechanical structure

Azimuthal ring

The azimuthal ring, an annular steel girder 16 m in diameter, will provide the track for the azimuthal (horizontal) movement and join the mount to the pier. It will be one of the components of the telescope base. The azimuthal ring will carry the full weight of the telescope via the azimuth hydrostatic bearings, which will smooth its movement and eliminate friction.
