Digital Sun Sensor

Chi tiết sản phẩm

The Digital Sun Sensor is a high-precision optical device designed to determine the orientation of a spacecraft by measuring the direction of the Sun. It works by detecting the Sun's position relative to the sensor’s field of view and converting this information into digital signals that can be processed by the spacecraft’s attitude control system. The sensor is equipped with an array of photodiodes or charge-coupled devices (CCDs), which capture the Sun's light, and the data is then processed to calculate the spacecraft’s orientation with high accuracy. The Digital Sun Sensor is commonly used in spacecraft for attitude determination, especially in low Earth orbit (LEO) and geostationary satellites. It is typically characterized by its compact size, low power consumption, and ability to operate in harsh space environments. The sensor provides real-time feedback on the Sun’s position, helping to maintain the spacecraft's stability and pointing accuracy during its mission, such as for solar panel orientation or scientific observations.
