Key highlights
A compact and reliable infrared earth horizon sensor that provides high-accuracy nadir determination throughout the entire orbit. This allows for accurate satellite control in eclipse without the need for a star tracker, making it a less expensive alternative. The Horizon Sensor is verified with our infrared lens calibration and earth emulator jig, which is an innovative in-house test set-up designed and built by CubeSpace (CS) engineers.

Testing & qualification
Our satellite subsystems’ manufacturing, assembly, integration, and testing adhere to international space standards. We design these subsystems with carefully selected components and subject them to rigorous testing under ESA’s ECSS and NASA’s GEVS standards, including radiation, vibration, shock, and thermal vacuum tests. Utilising in-house test equipment enables us to validate product performance efficiently and cost-effectively, ensuring reliable and high-quality products and services for our ambitious partners.
