Gen 1: CubeStar

Gen 1: CubeStar


CubeStar is a miniature, low-power, medium-accuracy star tracker for CubeSat and small satellites. The 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.
