Fine Sun Sensor Head Protective Cover, 4.5 x 2.5, labeled “Protective Cover…For a Fine Sun Sensor Head Remove Before Flight.” Cover comes from a Kennedy Space Center clean room. The Fine Sun Sensor, used on many spacecraft, consists of two independent single-axis sensor heads, nominally mounted perpendicularly. Digital Sun sensors are often used onboard spacecraft to measure the direction of the Sun for use in attitude determination and control. The fine Sun sensor (FSS) design combines a digital sensor with an analog component to improve the observation accuracy to 1 arcmin or better. In fine condition. RRAuction COA.
