The DJI O4 Ground Station - Reach Farther, Stay Aware
DJI O4 Ground Station features a 12-antenna array and automatic multi-band selection. The new Gateway Mode connects directly to FlightHub 2 to bypass deployment barriers, while Relay Mode supports offline reach. Maintenance-free by design, it drives 24/7 unattended operations.
High-Performance RF Unit
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.
Omnidirectional High-Gain Antenna
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.
Automatic Multi-band Selection
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 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
5-System, 19-Frequency GNSS
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.
Gateway Mode, Wide Coverage
Direct Network Connectivity: 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
Signal Map for Precise Deployment: 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.
Virtual Cockpit for Agile Control: 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.
Relay Mode, Offline Reach
High-Point Setup to Clear Obstructions : O4 Ground Station inherits the functions of the D-RTK 3 Relay Fixed Deployment Version. In offline areas such as valleys or urban environments with severe signal obstruction, operators can switch to Relay Mode [4] and position the station at a high point to extend aircraft video transmission range.
Multi-Device Rotation for Higher Utilization : Remote controllers or DJI Docks within signal range can remotely scan and connect to O4 Ground Station. This enables fast turnarounds, as a single station can service different aircraft sequentially and improve overall hardware utilization.
