Solar Array Drive Assembly (SADA) is the core component of a satellite's power system. It is primarily responsible for the directional drive of solar arrays (solar wings), adjusting their angle in real time to ensure sunlight strikes the photovoltaic cells at the optimal incidence angle, thereby maximizing energy capture efficiency. Additionally, it facilitates power and signal transmission between the solar arrays and the satellite body.

As the "energy heart" of a satellite, NBG has innovatively developed a dual-drive SADA capable of simultaneously managing two solar wings. By utilizing capacitive coupling contactless transmission technology for signal transfer, the system achieves significantly enhanced reliability.

Given the extreme operating conditions of satellites and the impossibility of maintenance, slip rings must meet exceptionally high standards for performance and reliability. Key technical requirements include:

- Capacitive Coupling Contactless transmission technology
- High reliability and long lifespan
- Ultra-low contact resistance variation
- Vibration and shock resistance
- Adaptability to vacuum and extreme temperatures
- Miniaturization and lightweight design
- High-density multi-channel integration
This advanced SADA technology ensures robust and efficient power management for next-generation satellite systems.

Slip rings are widely used in UAVs (unmanned aerial vehicles) to enable
continuous power and signal transmission between rotating and stationary
parts—most commonly in gimbals, radar units, and rotary sensors.
