Reach Farther, Stay Aware

Built to overcome signal limits, DJI O4 Ground Station features a 12-antenna array and automatic multi-band selection ^[1]. The new Gateway Mode ^[2] connects directly to FlightHub 2 ^[3] to bypass deployment barriers, while Relay Mode ^[4] supports offline reach. Maintenance-free by design, it drives 24/7 unattended operations.

Advanced Hardware. Robust Transmission

DJI O4 Ground Station

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 ^[1]

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 ^[5].

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 ^[2]
Wide Coverage

DJI O4 Ground Station

Direct Network Connectivity

In Gateway Mode ^[2], O4 Ground Station connects directly to DJI FlightHub 2 ^[3] via Ethernet or the DJI Cellular Dongle 2 ^[6], 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 ^[7].

Signal Map for Precise Deployment ^[8]

After a flight, FlightHub 2 utilizes flight data to generate a Signal Map ^[8] 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 ^[8]

In Gateway Mode, operators can use the FlightHub 2 Virtual Cockpit ^[8] 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 ^[4], Offline Reach

DJI O4 Ground Station

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 ^[9] for Higher Utilization

Remote controllers or DJI Docks ^[9] within signal range can remotely scan and connect to O4 Ground Station ^[10]. This enables fast turnarounds, as a single station can service different aircraft sequentially and improve overall hardware utilization.

Durable Design, Smart Power

DJI O4 Ground Station

All-Weather Reliability

DJI O4 Ground Station

An IP67 rating ^[11] protects against water and dust, while O4 Ground Station operates reliably in temperatures from -40° to 55° C (-40° to 131° F) ^[12]. This robust build supports continuous, unattended operations across harsh outdoor climates.

Lightning Protection

DJI O4 Ground Station

Proprietary lightning protection components and a grounding design meet the EN/IEC 61643-21 Category C standard. This helps mitigate the risk of lightning damage when deploying the station at elevated outdoor locations such as mountains or transmission towers ^[13].

Maintenance-Free Design

Fanless passive cooling and a self-recovery mechanism allow the station to automatically resume operation after power outages or software anomalies. This maintenance-free design reduces the need for manual on-site reboots and helps cut troubleshooting trips and operational costs.

Smart Low-Power Mode ^[8]

In Gateway Mode, O4 Ground Station features smart power management. It automatically hibernates when no aircraft is connected, drawing only 7 W on standby ^[14]. For off-grid environments, the station connects to DJI Power solar solutions or third-party photovoltaic systems ^[15], supporting long-term operations in remote areas.

Open Ecosystem, Flexible Integration

Unified Visual Management

O4 Ground Station integrates up to four standard IP cameras. Using ONVIF and GB/T 28181 protocols, it streams live video directly to DJI FlightHub 2 and synchronizes native camera alerts, such as displacement detection. FlightHub 2 also enables remote PTZ control (Pan/Tilt/Zoom) of connected cameras, giving operators a centralized, comprehensive view of the operational area.

Open ESDK

The new MQTT-based streamline integration, empowering developers to build custom, industry-specific solutions. Via the MQTT protocol, the station can connect to . This delivers real-time awareness of nearby unmanned and manned aircraft, proactively safeguarding the airspace around DJI Dock 3.
