nanoSSOC-D60 digital sun sensor

Flight heritage since 2016

nanoSSOC-D60 digital sun sensor


The Solar MEMS Sun Sensor on a Chip (SSOC) solution is a two-axes and low-cost sun sensor for high 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-D60 sun sensor is based on MEMS fabrication processes to achieve highly integrated sensing structures. The nanoSSOC-D60 has a digital interface (UART, I2C or SPI) and is compact, low weight and low power, making it ideally suited to nanosatellite platforms.

The nanoSSOC-D60 sun sensor includes MEMS technology with flight heritage and electronic components that are space-grade. More than 1000 flight units have been delivered since 2016, with hundreds of units in orbit.

Key features of the nanoSSOC-D60 sun sensor include:

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