Star Tracker systems determine the precise location and attitude of a satellite or spacecraft by analysing the placement of the surrounding stars relative to the payload. Star Tracker lenses are used to focus light from stars onto the image sensor. The accuracy and reliability of a star tracker is highly dependent on the performance of the optical system. Not only should Star Tracker lenses be robust to withstand the stress of space launch – they must also be lightweight and highly resilient to the radiation, wide temperature variation and vacuum conditions experienced in geostationary space orbit. Drawing upon extensive expertise in design and supply of space ready optics – Resolve Optics can develop compact, athermalized star tracker lenses to match even the most demanding application.
