The post explains that the towers are part of the C2 and C3 command, control, and communications structure. While the tower’s skeleton itself is not critical, three key factors are highlighted: height, structural stability (whether it remains intact after impact), and fixation. At the top of each tower sits a communication unit or relay that sends control commands, receives telemetry and flight data, captures mission imagery, extends communication range due to height, and maintains the link when the UAV leaves line of sight.
In aviation literature the UAV control link is often referred to as C2 or CNPC. The post notes that a higher antenna gain results in a narrower beam, so even a small angular error can cause significant signal loss. Therefore professional stations use precise mechanical and control systems, not just high transmitter power.
Typical components of such a system include a directional antenna or dish, azimuth/elevation base, cross‑level adjustment for base tilt, servo motor, angle encoder, gyro/IMU, tracking controller, auto‑tracking or beacon tracking, and a very rigid chassis or foundation. Marine and satellite antennas commonly use a tri‑axis architecture (azimuth, elevation, cross‑level) to keep the transmitting beam stable.
