A new tip tilt mechanism based on low voltage piezoelectric actuators has been designed by Cedrat
Technologies to answer the high level of stability required for the Earthcare satellite. The Beam Steering Assembly aims is to deviate a pulsed high energy UV laser beam to compensate for misalignment between the emission and reception paths of ATLID  with a very high stability and resolution. In this paper, the authors points out the BSM development with the main mechanism design issues including performances, mechanical and thermal stability; low power consumption; high integration level; high reliability and safety; cleanliness requirements and give the results of the qualification campaign done at Cedrat Technologies’ to establish the final functional performances in preparation of the Flight Models deliveries for the BSM.
