ACSS RH - Advanced Coarse Sun Sensor

Advanced Coarse Sun Sensor (ACSS) is a device for sun-tracking and attitude determination. This sensor measures the incident angle of sun ray in two orthogonal axes, providing a high sensitivity based on the geometrical dimensions of the design. ACSS sun sensor offers the highest reliability and radiation hardness for the most demanding LEO, MEO and GEO missions. CSS technology of Solar MEMS has light heritage since 2019 with hundreds of light units delivered, and its manufacturing process has been developed and industrialized for mass production.
