DJI Launches O4 Ground Station: Wide-Area Transmission System Built for All-Weather Drone Operations
DJI has introduced the O4 Ground Station, a ruggedized ground communications system integrating a high-performance RF module, a 12-antenna omnidirectional array, and automatic multi-band switching. Compatible with DJI Dock 3 in either Gateway or Relay mode, it achieves a maximum transmission range of 40 km when paired with the Matrice 400, with a standby power draw of just 7 W — designed for large-scale, unattended drone operations.
Highlights
- DJI launched the O4 Ground Station, a ground communications system featuring a 12-antenna omnidirectional array and automatic multi-band switching for wide-area drone operations.
- When paired with the DJI Matrice 400, the O4 Ground Station delivers a maximum transmission range of 40 km with a standby power consumption of just 7 W.
- The system supports two modes with DJI Dock 3: Gateway Mode for cloud-connected real-time control via FlightHub 2, and Relay Mode for offline communications in signal-obstructed areas.
- The O4 Ground Station is built for maintenance-free, all-weather operation, enabling continuous unattended drone missions without on-site technician presence.
- Target use cases include remote drone dock deployments, long-range industrial inspections, and 24/7 scaled drone programs in infrastructure-limited environments.
For large-scale drone operations, reliable communications infrastructure is mission-critical. A signal outage in the field doesn't just disrupt a single flight — it can bring an entire operational workflow to a halt. Whether the application involves drone docks at remote facilities, flight corridors through dense urban environments, or inspection routes across rugged terrain, ground communications infrastructure must deliver unwavering reliability.
DJI O4 Ground Station: A New Approach to Wide-Area Transmission
The DJI O4 Ground Station is designed precisely to address these challenges. The system combines a high-performance RF module, a 12-antenna omnidirectional array, and automatic multi-band switching to overcome the signal bottlenecks that have long constrained wide-area drone operations. All of this is packaged in a maintenance-free, all-weather-rated enclosure. The O4 Ground Station significantly extends operational coverage and redefines what is possible for unattended, continuous drone missions.
Two Operating Modes for Different Deployment Scenarios
When paired with the DJI Dock 3, the O4 Ground Station supports two operating modes:
- Gateway Mode: Connects directly to the FlightHub 2 cloud platform via Ethernet or cellular network, enabling real-time video streaming and remote control.
- Relay Mode: Supports offline communications in valleys, obstructed areas, or locations beyond cellular coverage, ensuring mission continuity without interruption.
Key Specs: 40 km Range, 7 W Standby Power
When deployed alongside the DJI Matrice 400, the system achieves a maximum transmission range of 40 km, with a standby power consumption of just 7 W. It is capable of continuous, unattended operation without the need for on-site routine maintenance.
The solution is particularly well suited to the following use cases:
- Drone dock deployments in remote or infrastructure-limited areas
- Long-range inspection missions in urban or industrial environments
- Scaled drone programs requiring 24/7 non-stop operations
The launch of the DJI O4 Ground Station marks a significant move by DJI into enterprise-grade ground communications infrastructure, providing a robust backbone for organizations seeking high-efficiency, high-reliability large-scale drone operations.
