Gen 1: CubeSense

Gen 1: CubeSense


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

  • All sensors are calibrated in our state-of-the-art clean and dark, optics calibration room, using a sun simulator and highly accurate rotation stage.
  • Based on a high resolution 1.3 megapixel imager, CubeSense offers better coverage than most sensors in the same performance range thanks to the wide field of view.
  • With simple and compact design; qualified in vibration, thermal, vacuum, and radiation; and used in operational missions since 2014.
