The Solar MEMS Sun Sensor on a Chip (SSOC) A60 is an analog sun sensor designed for space applications. It is based on MEMS fabrication processes to achieve highly integrated sensing structures for high accurate sun-tracking, positioning systems, and attitude determination.

The SSOC-A60 device measures the incident angle of a sun ray in two axes. Its high sensitivity is based on the geometrical dimensions of the design. It also includes MEMS technology with flight heritage and electronic components that are space-grade.

Every sensor is calibrated and characterized, and a look-up table is provided for its application. The use of a metal shield and a cover glass in the optical eye minimizes the aging of the device under high radiation levels.

Flight heritage

The Solar MEMS SSOC-A60 - Analog Sun Sensor on a Chip has the flight heritage since 2016, with hundreds of flight models delivered for different missions.

Export control

The Solar MEMS SSOC-A60 - Analog Sun Sensor on a Chip is ITAR Free.
