About
The Mechanical Unit of Antenna Pointing System Type 1 provides rotation of the antenna mounting plane relative to the antenna pointing system control module in two mutually perpendicular planes. It is a two-degree-of-freedom electromechanical drive for antenna pointing with a slew rate of 0.009–7.0 °/min per axis and minimum torque of 65 N·m, supporting load inertia up to 150 kg·m². The self-braking torque in de-energized state is at least 6 N·m per axis. Designed for 44,000+ hours operational life, 10-year active lifetime, and 14-year overall guaranteed lifetime. Delivery time 6 months.
