DJI O4 Ground Station

Robust Wide-Area Transmission System — Reach Farther, Stay Aware.

Built to overcome signal limits, the DJI O4 Ground Station features a 12-antenna array and automatic multi-band selection. A 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.

Advanced Hardware, Robust Transmission

• High-Performance RF Unit — High-output RF significantly boosts signal penetration and coverage, with an optimized signal-to-noise ratio that recovers usable signals in complex electromagnetic environments.
• Omnidirectional High-Gain Antenna — 12 internal and external antennas with horizontal and vertical polarization deliver omnidirectional, high-gain coverage regardless of aircraft position.
• Automatic Multi-Band Selection — Automatically shifts across sub-2G, 2.4 GHz, 5.2 GHz, 5.8 GHz, and other bands to bypass interference. Paired with DJI Matrice 400, supports transmission up to 40 km.
• 5-System, 19-Frequency GNSS — Integrated high-gain RTK module tracks 19 frequencies across five global satellite systems for continuous centimeter-level positioning.

Gateway Mode — Wide Coverage

• Direct Network Connectivity — Connects directly to DJI FlightHub 2 via Ethernet or the DJI Cellular Dongle 2, extending coverage up to 30 km and freeing the station from DJI Dock 3 proximity constraints.
• Signal Map for Precise Deployment — FlightHub 2 generates a Signal Map after each flight, visually highlighting weak coverage zones for precise station placement.
• Virtual Cockpit for Agile Control — Operators can remotely override preset routes via FlightHub 2 Virtual Cockpit for flexible, fast response to multi-point tasks.

Relay Mode — Offline Reach

• High-Point Setup to Clear Obstructions — Inherits the D-RTK 3 Relay Fixed Deployment functions; position at a high point to extend video transmission range in valleys or obstructed urban environments.
• Multi-Device Rotation — Remote controllers or DJI Docks within signal range can scan and connect to the O4 Ground Station, enabling fast turnarounds across multiple aircraft.

Durable Design, Smart Power

• All-Weather Reliability — IP67 rated; operates from −40 °C to 55 °C (−40 °F to 131 °F).
• Lightning Protection — Proprietary lightning protection and grounding design meeting EN/IEC 61643-21 Category C.
• Maintenance-Free Design — Fanless passive cooling and self-recovery mechanism automatically resume operation after power outages or software anomalies.
• Smart Low-Power Mode — In Gateway Mode, automatically hibernates when no aircraft is connected, drawing only 7 W on standby. Compatible with DJI Power solar solutions or third-party photovoltaic systems.

Open Ecosystem, Flexible Integration

• Unified Visual Management — Integrates up to four standard IP cameras via ONVIF and GB/T 28181 protocols, streaming live video to FlightHub 2 with remote PTZ control.
• Open ESDK — MQTT-based ESDK 2.0 and Cloud API enable custom integrations and connection to third-party Remote ID or ADS-B receivers for airspace awareness.
