SIMBA CubeSat with an arcsec ADCS

Arcsec's ADCS, including the star tracker and reaction wheels have successful flight heritage on board of the 3U ESA IOD CubeSat SIMBA. SIMBA was launched on September 3rd 2020 and all ADCS components have been fully functional since the start.

After one year in orbit, the ADCS, star tracker and reaction wheels show no sign of degradation. The mission has recently been extended to experiment further with the ADCS performance and to gather more sciencific data, that will help to research global warming.

The components of arcsec will be launched on several more missions in the coming months.
