Symétrie continues to provide hexapods for space applications. “They are used for aligning mirrors and calibrating optical instruments, as on the Gaia and Meteosat Third Generation satellites,” explains Thierry Roux, technical director at Symétrie.
“We have also made a motion hexapod for the Ariane 6 rocket, to simulate the movement of liquid oxygen in the tanks at launch.
“However, around 80% of our business is now for terrestrial applications. This includes positioning mirrors in particle accelerators and in ground-based telescopes.
