Abstract

In this paper we present recent progress on the Australian Astronomical Observatory's AESOP2 fiber positioner for 4MOST (on VISTA). As an evolution of the Echidna "spine" technology used for FMOS (on Subaru), AESOP has challenging requirements to position 2,448 fibers in parallel, within 1 minute, to an accuracy of < 10 um RMS. AESOP successfully passed ESO's official final design review and manufacturing has commenced. We present performance results from the first batch of newly-manufactured positioners and also report on how the AESOP project is tracking in terms of schedule, budget and risk.
