Sun Sensor on a Chip (SSOC) 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 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 tiny size, low weight and low power consumption to be the perfect ADCS solution for nanosatellite platforms like Cubesats.
