About

The Fine Sun Sensor Assembly (FSSA-110) developed by Berlin Space Technologies is a critical component for satellite attitude determination. It is designed to host up to three analogue fine sun sensors, allowing for precise measurement of the sun’s position relative to the spacecraft. The FSSA-110 can be strategically placed in remote locations on the satellite, providing flexibility in integration. It reports the sun vector information back to the On-Board Computer (OBC) for use in attitude control and navigation systems. The FSSA-110 boasts space heritage, having been utilized in space missions since 2015, demonstrating its reliability and performance in the harsh space environment. Its hemispherical coverage ensures a wide field of view for sun detection.
