In the news
- Strengthening Europe’s space security with European Space Agency - ESA’s IRIS² programme. We’re proud to be part of ARGUS—an innovative mission concept exploring how distributed satellite capabilities can enhance space domain awareness and support Europe’s strategic autonomy. Together with GMV and Alén Space, arcsec is contributing to the development of a constellation of up to five 16U CubeSats designed to detect radio-frequency interference, monitor the spectrum and deliver valuable insights to governmental users. By combining
- From spacecraft attitude determination to tracking objects in orbit, star trackers are capable of much more than many people realize. We're excited to share that arcsec will be presenting two papers at the 2026 AMOS Conference: 🚀 ASTRA-Net: A Hybrid CNN Detection and Poisson Labeled Multi-Bernoulli Tracking Framework for SSA using Star Trackers A novel approach combining AI-based detection and advanced multi-target tracking to enable Space Situational Awareness using star tracker imagery. 🚀 Assessing Space Debris Observability:
- Heading to the ESA Industry Space Days? arcsec will be there too. Book a meeting with us through the B2B platform to learn more about our star trackers, space situational awareness capabilities, reaction wheels, and ADCS solutions. See you there!
- Congratulations to ArkEdge Space Inc. for winning the Small Satellite Mission of the Year Award with ONGLAISAT!
- We're excited to be at #SmallSat2026! Come visit our booth to talk about star trackers, reaction wheels, ADCS and SSA!
- Heading to SmallSat 2026! 🛰️ We’ll be at the Small Satellite Conference from August 23–26! 🌟 Come meet us and let’s talk space, satellites, and the future of the industry. Whether you’re looking to connect, collaborate, or simply say hi, we’d love to see you there! 🤝 #SmallSat #SatelliteTechnology #SpaceIndustry
- We need accurate, complete, timely and affordable space situational awareness data. arcsec's star trackers are the perfect sensors to provide it!
- Kicking off MIMACOR! Our colleague Kurt Smets presented LAB Motion Systems' research on a 3DOF air bearing rotational motion platform for satellite and pointing equipment testing at the Open Day, hosted by Siemens Digital Industries Software. Proud to contribute to this three-year space research project alongside KU Leuven, arcsec, and Siemens. Stay tuned for more! #MIMACOR #NewSpace #MicroVibration #ShockTesting
