Reflector Drive Mechanism
- Purpose: Provides rotation of the large deployable antenna reflector relative to the reflector boom from the transportation to the operational position and reflector readjustment in the area of operating angles during orbital flight of the spacecraft.
- Guaranteed service life (years): 10
- Estimated production / delivery time (months): 6
