Closing Date: 16/02/2022 13:00 CEST

Each of the three LISA spacecraft includes an X-band High-Gain Antenna (HGA) equipped with an Antenna Pointing Mechanism (APM).For the LISA mission, the operation of the scientific instrument is incompatible with the uvibration perturbations induced by a conventional Antenna Pointing Mechanism.Therefore this activity shall conceptualise an APM design that fulfills the stringent LISA uvibration requirements. Due to the challenging nature of uvibration regarding design and specifically verification the activity shall in parallel also lead to the design of an appropriate verification GSE and associated analytical and/or numerical models that allow the simulation of the performance of the proposed design solution and associated verfication GSE. If required by the proposed design and solution trade-off, the performance of identified critical elements and components shall be evaluated and tested.
