Redwire Fine Sun Sensors (FSS50) are used in attitude control applications where sub-arcminute accuracy and millidegree angular resolution are required.
Redwire FSS50 is 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. The standard ±50° Fine Sun Sensor is rad hard to 100 krad (Si) by design, employing Hi-Rel components. An option for 150 krad is available. A separate option for 300 krad is also available.
Redwire FSS50 has flown on more than 100 spacecraft; applications include high accuracy attitude determination, payload instrument pointing, and gyro updates.
The key configuration characteristics include:
- Number of measurement axes: 1 (each sensor) (note: the two sensors can be mounted orthogonally and together function as a 2-axis sun sensor)
- Number of sensors: 2 (note: additional sensors can be paralleled as long as their fields of view do not overlap)
Sun Sensors are export controlled through an ECCN (Export Control Classification Number) issued by the United States Department of Commerce, ECCN 7A104. Export shipment requires successful application for an export license. Redwire is AS9100D/ISO 9001 certified.
