During this project, a 3-DOFs (1 translation & 2 rotations) long-stroke/high-precision mechanism has been developed. The mechanism can be used to control optical mirrors translational and rotational motions for interferometric space missions or for alignment/pointing/refocusing purposes on primary segmented or secondary telescope mirrors. It is based on the magnetic bearing technology that experiences contact free movements. This allows achieving simultaneously very high resolution and long strokes. The achieved performances of the mechanism are 1 nmrms over 5 mm for the translation DOF and 10 nradrms over 2.5 mrad for the two rotation DOFs. The power dissipation in the mechanism has been kept very low to allow its use in cryogenic applications. Thanks to an innovative magnetic design, the power dissipation in the mechanism has been proven to be less than 1 mW over the entire thermal range. The mechanism has successfully passed a dedicated test campaign, including random vibration exposure, functional test at extreme operational temperature and thermal cycling. a proto-flight model of the mechanism is currently being developed, to undergo in-orbit test on board a Space Shuttle GAS Canister carrier. This activity has been performed under the ESA GSTP research and technology program.
