About
The ST200 is one of the world’s smallest fully autonomous star trackers, developed with Hyperion Technologies B.V., with over 100 units delivered to customers, suitable for CubeSats and nanosatellites. It offers high pointing accuracy at 10 arcsec pitch/yaw and 70 arcsec roll (1 sigma) at a 5 Hz update rate and 1°/s slew rate tolerance, operating on 3.7-5V DC via UART or RS422 interface, radiation tested to 11 krad (130 MeV proton), with a 5-year LEO design life.
