ATS Site Equipment

The four auxiliary telescopes (ATS) of the VLT interferometer can be anchored on 30 different docking stations: the numerous possible baselines (combination of two telescopes) enhance drastically the observation capabilities of the interferometer.

This concept of movable telescopes is unique. Any telescope can be relocated from one station to any other in less than 3 hours. The enclosure frame surrounding the telescope supports the telescope during the relocation. The system is autonomous and self-propelled: the air conditioning, liquid cooling, hydraulic group, pneumatic group and all the electronics are integrated to the enclosure.

The Auxiliary Telescope is moving on a rail network. It is capable of changing direction at a rail crossing thanks to four articulated wheels.

Thanks to the high accuracy of re-positioning of a telescope on a docking station, the telescope is directly operational after relocation.

AMOS has developed all the site equipment related to the 30 observation stations. This includes the rail network and the 30 docking stations but also all the support equipment necessary for the installation and alignment of the 30 stations. The high accuracy alignment of the station -up to 130m from each other- could be achieved by specific tools that are used in conjunction with high accuracy survey tools.
