VECTRONIC - Model VST-68M, VST-41M -Star Trackers

SHARE
VECTRONIC Aerospace offers the VST-series, high-performance star trackers designed for small satellite applications with robust technical capabilities and radiation tolerance suitable for LEO, GEO, and even interplanetary missions. The VST-68M star tracker features a 1024 x 1024 pixel rad-hard CMOS sensor for direct and autonomous measurement of spacecraft attitude relative to the celestial reference system J2000. Its advanced CPU analyses star data using algorithms to eliminate noise and bright objects, ensuring accuracy. With a 75 mm focal length, it provides a 14°x14° FOV ensuring visibility of at least 16 stars. The VST-41M, equipped with a 512 x 512 pixel rad-hard CMOS sensor, similarly measures spacecraft attitude with high precision. With a 50 mm focal length, it also offers a 14°x14° FOV with at least 10 visible stars. Both models support quaternions and Euler angles for attitude information and feature independent asynchronous SCI interfaces with up to 1 Mbit baud rate and redundant CAN bus interface. The VST-41M further boasts a quick first acquisition time of 800 ms and operates at an update rate of 4 Hz with an accuracy of better than 18 arcsec, and a high probability of attitude acquisition under specific conditions.
