The RF unit with high-output capabilities significantly boosts signal penetration and coverage, securing reliable links through dense urban obstructions. An optimized signal-to-noise ratio (SNR) further enhances receiver sensitivity, recovering usable signals even in complex electromagnetic environments.

Using 12 internal and external antennas with horizontal and vertical polarization, O4 Ground Station delivers omnidirectional, high-gain coverage. It can continuously and stably capture signals regardless of the aircraft's position, helping maintain a seamless communication link for wide-area operations.

To navigate congested urban RF environments, O4 Ground Station automatically shifts across sub2G, 2.4 GHz, 5.2 GHz, 5.8 GHz, and other bands ^[1] to help bypass interference. This delivers a crisp, stutter-free video feed, and when paired with DJI Matrice 400, supports a transmission range of up to 40 km.

An integrated high-gain RTK module tracks 19 frequencies across five global satellite systems. Even in challenging, semi-obstructed environments like urban canyons or dense canopies, it rapidly acquires satellite signals. This provides continuous, centimeter-level positioning data, safeguarding flight operations.

In Gateway Mode, O4 Ground Station connects directly to DJI FlightHub 2 via Ethernet or the DJI Cellular Dongle 2 , delivering low-latency, high-bandwidth video feeds. This frees the station from DJI Dock 3's proximity constraints, allowing it to extend coverage up to 30 km.

After a flight, FlightHub 2 utilizes flight data to generate a Signal Map that visually highlights weak coverage zones. This helps operators position ground stations more precisely and reinforce communication links, enhancing overall flight safety.

In Gateway Mode, operators can use the FlightHub 2 Virtual Cockpit to remotely control the aircraft. Within the ground station's coverage area, pilots can manually override preset routes, enabling a flexible and fast response to multi-point task requirements.
