As UAV technology advances, the demand for high-bandwidth microwave data links has significantly increased. Traditional methods of enhancing long-distance communication through higher transmitter power or improved receiver sensitivity are no longer sufficient. We have discovered that enhancing the receiving and transmitting gain of ground control antennas is an effective solution that does not add weight or size to airborne communication equipment.
Directional communication antennas are essential for the measurement and control of medium to long-range UAVs, as they provide high gain within specific beam angles. By directing the radiation and reception of signals, these antennas maximize energy efficiency, reducing energy loss and improving transmission gain. However, due to their directional characteristics, it is crucial for these antennas to be paired with a guidance tracking system, enabling dynamic tracking communication for UAV operations.
Our system employs BD/GPS modes and brushless servo motor control to achieve precise one-dimensional servo control for various types of directional antennas, including spiral, Yagi, and grid antennas. This setup offers greater stability compared to single-channel monopole tracking systems while being cost-effective and digitally advanced.
The turntable captures flight control data using the MAVLink protocol, facilitating real-time tracking of the aircraft's position, altitude, and other critical information. The MAVLink protocol is widely adopted by numerous flight controllers, ground control stations (GCS), and tracking devices. However, many manufacturers implement MAVLink differently, as it has not clearly defined the transmission of vital data between UAVs and GCSs. There is a variety of MAVLink messages available to convey information such as BD/GPS coordinates and altitude.
