The NSS3 Sun sensor was designed with an emphasis on the smallest possible size while preserving outstanding precision of <0.2 deg. It is a great choice for CubeSat missions with a tight mass and energy budget with high ADCS requirements. The device has a digital I2C interface, it is fully autonomous and easy to use. The Sun sensors have the ability to work independently of the onboard computer. The calculations are done by a built-in microcontroller providing the user with calibrated information about the sun position angles in two axes.
