Application :

● The key technology of airborne SOTM antenna is to isolate the external disturbance caused by the movement of the airframe by the servo control system during the flight of the aircraft, so that the antenna can always track the target satellite.

● It can realize uninterrupted multimedia communication such as voice, data and video in high-speed motion environment, so it is widely used in battlefield reconnaissance command, rescue and disaster relief.
