SSOC-A60 2-Axis analog sun sensor
The Solar MEMS Sun Sensor on a Chip (SSoC) solution 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. The high sensitivity is based on geometrical dimensions of the design. The device 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 ageing of the device under high radiation levels.
SSOC-A60 has flight heritage since 2009, with hundreds of flight models delivered for different missions.
