SASC Sub-Arcsecond Star Camera
The SASC is a sub-arcsecond star camera offering high accuracy and precision for attitude determination, designed for plug-and-play integration with full-sky catalog onboard.
Description
The SASC (Sub-Arcsecond Star Camera) is a high-performance star camera designed for precise attitude determination in various environments, including Low Earth Orbit (LEO). It boasts a full-lost accuracy of less than 1 arcsecond at 10 Hz and a differential precision of 0.23 arcseconds at 60 Hz. The camera can handle a maximum slew rate of 1 dps. It features a plug-and-play design with a full-sky catalog onboard for immediate use. Communication options include GigE or RS-232/485, and data can be output in quaternion or matrix format. The SASC operates on 5W power at 12 VDC and is available in 1U, 2U, and 3U versions, with masses ranging from 100g to 400g depending on the application. It is designed to be radiation-tolerant for terrestrial, high-altitude (<40 km), and LEO (<700 km) environments, and operates within an industrial temperature range of -40 to 85°C.
