Abstract

Microscope successfully completed in November 2016 its on-orbit assessment. The paper begins with a brief description of the mission, the challenging performances the DFACS has to comply with and how they led to the hardwareand software design. Then we go through the major phases of the commissioning months for DFACS, from the first switch-on of the scientific instrument, the star-trackers and the propulsion system until getting all of them in the same control loop and carrying out definitive tunings to reach full performance. At the end of the commissioning, we look overthe most striking on-orbit observations: the linear and angular perturbations and the micro-perturbations. We finally poin tout the DFACS overall performances: the finest ever achieved on low earth orbit.
