Solar Array Drive Assembly (SADA)
Type SADA-1-2-2-2B SADA is designed with lightweight method. And it is the lightest SADA which is developed and applied in the practical engineering by SAST.The mechanism has 4-level maturity. It is applied successfully in satellites, Lunar exploration and deep-space detection. The product design life can be over 5 years(LEO). It can be promoted and widely applied on driving solar array of spacecrafts.
