The CubeSpace CubeStar is a miniature, low-power, medium-accuracy star tracker designed for CubeSat and small satellites. Its low power is achieved by lowering the update rate to 1 Hz, using a wide field-of-view lens, and designing power-efficient electronics. CubeStar outputs inertially referenced attitude quaternions or matched vector pairs for use in an external ADCS application.

Key features

  • Low power – less than 142Mw average power
  • Wide FOV lens – 99% sky coverage
  • Low mass – less than 60g
  • Simple design with 4 mounting holes

Flight heritage

The GEN1: CubeStar has achieved flight heritage since 2014.
