The Solar MEMS Sun Sensor on a Chip (SSOC) D60 is a digital sun sensor designed for space applications. It includes MEMS technology with flight heritage, electronic components that are space-grade, and a microprocessor included has been tested for the space environment and has flight heritage.

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-D60 sensor measures the incident angle of a sun ray on both axes. It includes a microprocessor that directly provides the sunlight incident angles and their derivatives without external calculations, via a digital interface.

The high sensitivity is based on the geometrical dimensions of the design. The use of a metal shield and a cover glass minimizes the aging of the device under high radiation levels. Every sensor is calibrated and characterized.

Flight heritage

The Solar MEMS SSOC-D60 - Digital 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-D60 - Digital Sun Sensor on a Chip is ITAR Free.
