Fine Sun or Earth Sensor

CubeSense is a CMOS-based Sun and Earth sensor with a wide field of view, low power usage and high accuracy. CubeSense is a highly compact, single sensor head with integrated electronics.

These sensors provide Sun/Earth measurements with <0.2° (3σ) accuracy over a 180° field of view. The sun sensors are completely immune to albedo effects, making them highly robust and versatile. All sensors are calibrated in our state-of-the-art dark calibration room, using a sun simulator and highly accurate rotation stage. CubeSense has flight heritage for a wide variety of missions and orbits.
