About
The Sagitta star tracker is arcsec’s standard, fully autonomous star tracker designed to fit in a CubeSat. It features an integrated baffle to reduce stray light effects and delivers arc second range pointing accuracy. The custom algorithms are optimized for accuracy, robustness, and low computational cost. Sagitta achieves a cross-boresight accuracy of 2″ (1σ) and along-boresight accuracy of 10″ (1σ). It communicates via RS485 and operates on 5V. arcsec reports 99.9% availability across night sky scenarios and more than 5 years cumulative heritage in space with over 100 systems sold worldwide.
