The Solar MEMS nano Sun Sensor on a Chip (SSOC) A60 is an analog sun sensor designed for Nanosatellites. It is a low-cost and two-axes sun sensor for highly accurate sun-tracking, pointing, and attitude determination. The device measures the incident angle of the sun ray in two orthogonal axes, providing a high sensitivity based on the geometrical dimensions of the design.

The nanoSSOC-A60 sun sensor is based on MEMS fabrication processes to achieve highly integrated sensing structures. It has an analog interface and is compact, low weight, and low power, making it ideally suited to nanosatellite platforms.

The nanoSSOC-A60 sun sensor includes MEMS technology with flight heritage and electronic components that are space-grade. There are hundreds of units in orbit since 2016.
