Arcsec is a spinoff company of the KU Leuven university in Belgium. Arcsec develops high accuracy attitude determination and control systems for CubeSats and SmallSats. Our product portfolio includes fully autonomous attitude determination and control systems (ADCS), star trackers and reaction wheels.
It is the mission of Arcsec to deliver the highest accuracy attitude determination and control systems.
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.
