Fine Sun Sensor (±50°)

Redwire Fine Sun Sensors are used in attitude control applications where sub-arcminute accuracy and millidegree angular resolution are required.

Redwire Fine Sun Sensors are designed in single or two-axis configurations.Each sensor can be custom designed to meet specific performance
requirements for Field of View (FOV), accuracy, resolution, and other key parameters.

Redwire Fine Sun Sensors have flown on more than 100 spacecrafts; applications include high accuracy attitude determination, payload instrument pointing, and gyro updates.

Radiation: The standard ±50° Fine Sun Sensor is rad hard to 100 krad (Si) by design. An option for 150 krad is available. A separate option for 300 krad is also available.
