The airborne satcom antennas have autonomous capabilities to acquire the longitude, latitude, and direction of the aircraft, automatically track the target satellite, and display the antennas azimuth and elevation angles.
It is equipped with an independent composite navigation unit, allowing for autonomous satellite acquisition. The system can automatically control the antennas alignment with the satellite-based on input parameters.
It provides two methods of satellite tracking: real-time automatic tracking and manual tracking.
Additionally, it is equipped with memory functions and power-off protection capabilities and also includes self-diagnosis, status inquiry, and fault alarm functions.
