Gen 2: CubeStar

Gen 2: CubeStar


A medium to high accuracy star tracker designed for low power consumption, in a small form factor. The tracker outputs quaternions directly and has both “lost in space” and tracking modes. A variety of baffles can be screwed directly onto the baffle thread, making it easily customizable for any mission.
