About
The Fine Sun Sensor (FSS) is a compact, low-power, and high-accuracy sun sensor specifically developed for CubeSats and SmallSats. It is designed to provide precise sun vector measurements, which are crucial for attitude determination and control systems (ADCS) in space applications. The sensor utilizes a photodiode array to detect the sun’s position, offering a wide field of view and high resolution. Its robust design ensures reliable operation in the harsh space environment. The FSS is an essential component for missions requiring accurate pointing, solar panel orientation, or general spacecraft attitude knowledge. Its small size and low power consumption make it ideal for resource-constrained small satellite platforms.
