System Composition
1. Antenna and Feed Subsystem: Prime-focus antenna with carbon-fiber reflector, Ku-band dielectric feed, Ka-band dielectric feed, Ku-band polarization assembly, Ka-band polarization assembly, etc.
2. Antenna Control Subsystem: Azimuth motor, elevation motor, polarization motor, etc.
3. Tracking Subsystem: Beacon receiver, angle sensors, GPS, Wi-Fi module, ATPC control board, etc.
4. Power Supply Subsystem: PSU power supply unit.

System Features

1. The antenna adopts a prime-focus carbon-fiber parabolic reflector. Approximately 60% of the overall system structure uses carbon-fiber material, providing better material stability, lighter weight, and higher strength, making it more suitable for portable applications.
2. A hat-shaped dielectric feed is used to ensure high antenna gain and low sidelobe levels, providing excellent RF performance.
3. The antenna system is equipped with a GPS positioning system, position detection system, polarization adjustment system, servo drive system, automatic protection system, high-performance satellite beacon receiving system, antenna controller, intelligent control and management software, etc.
4. One-button operation enables the antenna to automatically complete positioning, deployment, and satellite acquisition within 3 minutes.
5. Under special circumstances when GPS is unavailable, the satellite longitude and latitude can be entered manually to quickly complete satellite acquisition.
6. Both motorized and manual control modes are provided, allowing emergency operation under different environmental conditions.
7. A mobile APP and WEB monitoring interface are provided, allowing satellite parameter configuration and system status monitoring via mobile phone.
