AAT (Automatic Antenna Tracker) and flat directional fiberglass antennas are very helpful for improving signal sensitivity and transmission distance of drones’ wireless video and data systems.
Some customers want to manually send commands to AAT (Automatic Antenna Tracker) via UART AT commands so that it can adjust to the default angle when it loses signal. This function can also be realized automatically by working with your ground control station software. So how can it be realized? Please download and upgrade the AAT software first.
