Star Tracker – CubeStar
Price on request
CubeStar is a medium-to-high accuracy miniature star tracker equipped with an external thread for the easy integration of a mission-specific baffle, allowing you to customize the performance as per your mission objectives. CubeStar outputs quaternions and has both “lost in space” and tracking modes. Additionally, to support the high-volume production of these sensors and reduce lead times, CubeSpace (CS) has novel in-house designed and built dark optics tunnels, which allows for the concurrent calibration of multiple CubeStar’s in parallel. The modular design of these tunnels makes them easily scalable based on production demands.
