The STAR-S Star Simulator is a compact Optical Ground Support Equipment (OGSE) solution designed for high-precision Star Tracker testing in Thermal Vacuum (TVAC) environments.

Using highly stable and controlled LED light sources, STAR-S accurately reproduces star patterns under repeatable test conditions, supporting reliable verification and validation of Star Tracker performance throughout spacecraft development and qualification.

Its compact, robust and plug-and-play design simplifies integration into ground test setups, reducing testing complexity while providing a practical and cost-effective solution for demanding environmental test campaigns.

STAR-S enables spacecraft manufacturers and integrators to perform controlled, repeatable Star Tracker testing under representative conditions, supporting efficient system verification before flight.
