nanoSSOC-D60 digital sun sensor


Sun Sensor on a Chip (SSOC) is a two-axis and low-cost sun sensor for high accurate sun-tracking, pointing and attitude determination. The device measures the incident angle of a sun ray in two orthogonal axes, providing a high sensitivity based on the geometrical dimensions of the design. nanoSSOC sun sensor is based on MEMS fabrication processes to achieve high integrated sensing structures. nanoSSOC-A60 has minimum size, weight and power consumption to be the perfect ADCS solution for nanosatellite platforms like CubeSats.
