About
Bradford’s Redundant Cosine Sun Sensor (COSS-R) provides internal redundancy for mission-critical attitude determination in an ultralight 15 g package. Same 160×160° FOV and ±3° (3σ) OBC-limited accuracy as the CoSS, with passive analogue current or voltage output, >100 kRad TID resilience, and insensitivity to SEE. Ideal for missions where sensor failure is not acceptable.
