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 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 like CubeSats.

The nanoSSOC-A60 sun sensor includes MEMS technology with flight heritage and electronic components that are space-grade. More than 50 units have been included in more than 10 missions.

Key features of the nanoSSOC-A60 sun sensor include:

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