Key highlights
The Fine Sun Sensor Assembly (FSSA-110) of Berlin Space Technologies hosts up to three analog fine sun sensors. The FSSA can be placed in remote locations of the satellite and reports the sun vector back to the OBC. The FOV of one sensor reaches up to 114°. In order to sense the sun from all directions, 2 units are required. The FSSA-110 is the second generation of our flight-proven FSSA-100 with only minor modifications on it.
