Scorpio - Star Tracker

Scorpio is the rugged version of Sagitta Star Tracker(also by arcsec), designed for harsher environments with higher radiations and longer missions. It has a built-in extended baffle and an accuracy of 2 arcsec (1σ) cross-boresight and 10 arcsec (1σ) along-boresight.

Scorpio can also detect space debris during the course of its operation and is eligible to participate in the DeDUST program.

Scorpio can be further customized with extra coatings.
