Nano-SSOC-A60 analog sun sensor

Flight heritage since 2016

Nano-SSOC-A60 analog sun sensor


The Solar MEMS Sun Sensor on a Chip (SSOC) solution is a two-axes and low-cost 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. The nanoSSOC-A60 has 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.

Key features of the nanoSSOC-A60 sun sensor include:

  • ITAR free
  • Analog space qualified
  • Compatible with most nanosatellite structures
  • Compatible with most OBCs
