As the UAV technology evolves, the demand for high-bandwidth microwave data links has significantly increased. Traditional methods, such as enhancing ground or airborne transmitter power or increasing receiver sensitivity, no longer suffice for long-distance communications. We have identified a solution: enhancing the receiving and transmitting gain of ground control antennas, which can be achieved without escalating the weight and size of airborne communication devices,
, Directional communication antennas are extensively utilized for medium to long-range UAV measurement and control due to their high gain across various beam angles. These antennas focus radiation and reception to optimize energy within the desired range, minimizing energy loss and enhancing transmission gain. However, the directional nature of these antennas necessitates the integration of a guidance tracking system, enabling dynamic tracking communication for UAVs,
, By employing BD/GPS mode and brushless servo motor control, our system offers one-dimensional servo control for directional antennas, including spiral, Yagi, and grid antennas. This solution is more stable than traditional single-channel monopole tracking systems and is cost-effective while providing enhanced digital performance,
, The turntable captures flight control data using the MAVLink protocol, allowing for the identification and real-time tracking of the UAV's position, altitude, and various parameters. Many flight controllers and ground control stations (GCSs) implement MAVLink, although its usage can vary between devices due to ambiguities in defining the transmission of crucial data, such as aircraft to GCS communications. Numerous MAVLink messages exist for conveying vital information, including BD/GPS coordinates and altitude,
, As a leading China supplier and manufacturer in this domain, our factory is committed to delivering cutting-edge solutions that enhance UAV communications while ensuring reliability and performance.
