Nano-SSOC-A60 analog sun sensor
€2,500
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
