Details

Low-power miniature star tracker.

CubeStar is a medium-to-high accuracy miniature star tracker equipped with an integrated baffle. 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 has novel in-house designed and built dark optics tunnels, which allows for the concurrent calibration of multiple CubeStar’s. The modular design of these tunnels makes them easily scalable based on production demands.
