DJI O4 Ground Station โ “When Video Transmission Is No Longer the Bottleneck”
The DJI O4 Ground Station is a fixed ground station purpose-built to extend signal coverage for DJI Dock operations and unlock new, flexible deployment options. With a 12-antenna high-gain array, automatic multi-band selection, and a maximum transmission range of 40 km, the O4 Ground Station delivers significantly stronger signal transmission and reception than the D-RTK 3 Relay Fixed Deployment Version it replaces.
Built for all-weather reliability and smart energy efficiency, the O4 Ground Station keeps dock operations running in demanding environments โ from extreme temperatures and high altitudes to fully off-grid, solar-powered deployments.
ADVANCED HARDWARE, ENHANCED SIGNAL TRANSMISSION & RECEPTION
- High-Performance RF Unit โ extended signal coverage range with optimized SNR for stronger receiver sensitivity
- Omnidirectional High-Gain Antenna โ 12-antenna array with horizontal and vertical polarization, delivering stable signal capture from any direction with no blind spots
- Automatic Multi-band Selection โ supports sub2G / 2.4 / 5.2 / 5.8 GHz bands for maximum transmission range up to 40 km
- 5-System, 19-Frequency GNSS โ centimeter-level positioning, the strongest satellite reception among DJI enterprise products
TWO OPERATING MODES FOR DIVERSE DEPLOYMENT SCENARIOS
- Gateway Mode (New) โ connects directly to FlightHub 2 via Ethernet or DJI Cellular Dongle 2, with no dock binding required; select any nearby ground station per mission with no line-of-sight or distance limit
- Relay Mode โ inherits all functions of the D-RTK 3 Relay Fixed Deployment Version, acting as an extended antenna for the dock; requires dock binding and line-of-sight, no internet connection needed
HIGH RELIABILITY, SMART ENERGY SAVING
- IP67 rated, IK07 impact resistant, built for stable operation from -40ยฐC to 55ยฐC at altitudes up to 6,000 m
- Self-recovery mechanism โ internal subsystems back each other up and automatically restart after a fault or power interruption
- Smart Low-Power Mode โ automatically hibernates when no drone is connected, drawing as little as 7W on standby; supports solar and off-grid power via DJI Power or third-party PV systems
OPEN ECOSYSTEM, FLEXIBLE INTEGRATION
- Third-party camera integration โ live video, PTZ control, zoom, and motion/occlusion alerts directly in FlightHub 2
- RID & ADS-B Receiver โ real-time detection of nearby drones or manned aircraft, with configurable alert range
- M400 Delivery Mode (coming soon) โ cargo delivery with the DJI Matrice 400, including multi-point hopping between ground stations
- Signal Map โ a hexagonal heatmap of signal strength built from real flight data, for precise ground station deployment planning
WHO IS THE O4 GROUND STATION FOR?
The O4 Ground Station is best suited for:
- Dock operators who need extended signal range beyond a single fixed relay point
- Sites with limited or no network access requiring off-grid, solar-powered deployment
- Multi-dock operations such as reservoir patrol, infrastructure inspection, or wide-area monitoring
- Operations that need third-party camera integration or real-time airspace awareness (RID/ADS-B)
It’s compatible with DJI Dock 1/2/3 and designed to work alongside FlightHub 2 for centralized, multi-project fleet management.
