SURES Hexapod Astronomy

SURES Hexapod Astronomy


SURES hexapod is a very high accurate and stiff positioning system. It allows the adjustment and the set up of objects of up to 500 kg with high resolution and low cross-coupling (parasitic motions).


SURES Datasheet

Linear travel range ± 12 mm
Resolution 0.1 µm
Repeatability ± 0.5 µm
Payload 100 to 500 kg
Options Customized platform design
Modular external diameter


SURES hexapod is particularly adapted to the fields of space, astronomy and telescopes. For example it can align M2 and M3 mirrors on ground-based telescopes to realign them correctly to compensate the deformation of the structure due to gravity changes and temperature variations during the night.

The mechanics and electronic components of SURES hexapod are designed to work in cold environment as most of ground-based telescopes are installed on top of mountains in high altitude.


► Positioning of M2 or M3 mirror on optical telescope

► Positioning of subreflector on radio telescope

► Optical adjustment
