About
Bradford’s Mini Fine Sun Sensor (Mini FSS) provides ±0.2° (3σ) accuracy across a 128×128° FOV in a compact 50 g, 50×46×17 mm form factor. Operates with zero power draw (passive analogue output 0–5V via 9-pin micro-D connector), making it ideal for cubesat and small satellite applications. 22.3 FIT at 30°C reliability. A Look-Up Table (LUT) provided for OBC implementation enables ±0.005° noise equivalent angle.
