Micro Sun Sensor

The smallest sun sensor in the Redwire product portfolio, the Micro Sun Sensor can be used for a variety of spacecraft missions requiring sun detection.

One of the smallest sun sensors available on the marketplace today, the Micro Sun Sensor provides a cosine output of the sun angle for small satellite applications. The product offers these advantages:

  • Extremely low mass
  • Low power requirement
  • Sensor provides UV and RAD tolerant device for sun angle applications

The Micro Sun Sensor can be used for a variety of spacecraft missions requiring sun detection. The output of the Micro Sun Sensor is analog voltage range from 0 to 2.1V, which can be fed into a microprocessor ADC.

A single sun sensor can provide sun presence information. A group of sun sensors appropriately mounted can provide coarse sun angle data and polarity.
