About
The Mechanical Unit of Antenna Pointing System Type 3 provides rotation of the antenna mounting plane relative to the antenna pointing system control module in two mutually perpendicular planes. It features asymmetric rotation angles (±10° and ±90° per axis), a minimum torque of 60 N·m, and load inertia capacity up to 160 kg·m². Self-braking torque in de-energized state is at least 20 N·m per axis. Designed for 10,000+ hours operational life, 15-year active lifetime, and 19-year overall guaranteed lifetime. Delivery time 6 months.
