Arcsec – High-Precision ADCS for European Space Autonomy
Arcsec NV is a Belgian space technology venture pushing the frontiers of precision in satellite control. Founded as an academic spin-off in 2020, the company has swiftly gained attention for delivering attitude determination and control systems (ADCS) that set new standards in accuracy for micro- and nanosatellites. From its origins at KU Leuven to partnerships with European institutions, Arcsec represents a broader narrative of Europe’s drive for strategic autonomy in space. In an era when secure satellite operations and space situational awareness are paramount, Arcsec provides a home-grown solution that reduces reliance on non-allied suppliers. The company’s star-tracking sensors and control actuators enable even tiny CubeSats to orient with arcsecond-level precision, a capability once reserved for large, expensive spacecraft. This rare combination of academic pedigree and strategic relevance makes Arcsec an intriguing case of a European startup translating cutting-edge research into operational defense and dual-use technology.
