Drone ground station O4

Overview
Built to overcome signal limits, the DJI O4 Ground Station features a 12-antenna omnidirectional array and automatic multi-band selection. Gateway Mode connects directly to FlightHub 2 to enable low-latency networked operations, while Relay Mode extends offline reach. Designed for continuous, unattended deployment with maintenance-free hardware.

Key Features

• 12-antenna omnidirectional, high-gain array with horizontal and vertical polarization for consistent coverage regardless of aircraft attitude.
• High-output RF unit with optimized SNR to improve receiver sensitivity in complex electromagnetic environments.
• Automatic multi-band selection across sub2G, 2.4 GHz, 5.2 GHz, 5.8 GHz and other supported bands to mitigate interference.
• Gateway Mode: direct connectivity to FlightHub 2 (Ethernet or DJI Cellular Dongle 2) for low-latency, high-bandwidth video and control links.
• Relay Mode: offline relay capability for extending transmission from elevated positions where direct network access is unavailable.
• Maintenance-free design: fanless passive cooling and self-recovery mechanisms for automatic restart after power or software anomalies.

Operational Capabilities

• Long-range transmission: up to 40 km in open outdoor environments when paired with Matrice 400 under IC compliance; up to 30 km achievable with Matrice 4-series or Dock 3 in specific configurations (measured conditions apply).
• Smart Low-Power Mode: in Gateway Mode the station can hibernate when no aircraft are connected, drawing approximately 7 W in standby (station only; total PoE++ system draw will be higher).
• High-point deployment: Relay Mode supports placement at elevated locations to extend coverage in valleys or obstructed urban environments.

Positioning & Awareness

• Integrated high-gain RTK module: supports 19 frequencies across five global GNSS systems to deliver rapid acquisition and continuous centimeter-level positioning in semi-obstructed environments.
• Signal Map: FlightHub 2 generates post-flight signal maps to identify weak coverage areas and optimize station placement.
• Virtual Cockpit (Gateway Mode): remote aircraft control within station coverage via FlightHub 2, including manual override of preset routes.

Integration & Ecosystem

• Unified visual management: supports up to four standard IP cameras (ONVIF and GB/T 28181); streams live video to FlightHub 2 with remote PTZ control and camera alert synchronization.
• Open ESDK & Cloud API: MQTT-based ESDK 2.0 and Cloud API enable custom integrations and connection to third-party Remote ID or ADS-B receivers for real-time airspace awareness.
• Multi-device rotation: remote controllers or compatible docks can scan and connect to the station sequentially to service multiple aircraft.

Durability & Power

• All-weather protection: IP67 rating for ingress resistance in controlled test conditions.
• Operating temperature: -40° to 55° C (-40° to 131° F). Operation below -20° C requires a PoE++ power supply of 60 W or higher.
• Lightning & surge protection: proprietary grounding and lightning protection design meeting EN/IEC 61643-21 Category C; RJ45 surge protection rated 1.5 kA (8/20 μs waveform).
• Off-grid power: compatible with DJI Power solar solutions or third-party photovoltaic systems for remote deployment (sold separately).

Supported Models (examples)

• Gateway Mode: DJI Dock 3.
• Relay Mode: DJI Dock 3; DJI Matrice 400; DJI Matrice 4E; DJI Matrice 4T; DJI Matrice 4D and 4TD (dependent on remote controller models and local frequency support).

Service & Protection

• DJI Care Enterprise and DJI Care Enterprise Plus options available for extended protection, covering repair services, fleet coverage sharing and expert support (terms and availability vary by region).

Technical Specifications

• Antennas: 12 internal and external antennas with horizontal and vertical polarization; omnidirectional high-gain coverage.

• Multi-band support: automatic switching across sub2G, 2.4 GHz, 5.2 GHz, 5.8 GHz and other bands.
• Transmission range (measured, open environment): up to 40 km (Matrice 400, IC compliance); up to 30 km with Matrice 4-series/Dock 3 in specific configurations.
• GNSS: integrated RTK module supporting 5 GNSS systems and 19 frequencies for centimeter-level positioning.
• Modes: Gateway Mode (FlightHub 2 connectivity via Ethernet or DJI Cellular Dongle 2); Relay Mode (offline relay to extend reach).
• Management & integration: FlightHub 2 compatibility (Signal Map, Virtual Cockpit), ESDK 2.0 (MQTT), Cloud API, ONVIF & GB/T 28181 camera support, remote PTZ control.
• Environmental rating: IP67 (measured in controlled conditions).
• Operating temperature: -40° to 55° C; PoE++ >= 60 W required for operation below -20° C.
• Power consumption (standby, station only): approx. 7 W in smart low-power hibernation.
• Physical protection: proprietary lightning protection; RJ45 surge protection 1.5 kA (8/20 μs), EN/IEC 61643-21 Category C compliance.
• Maintenance: fanless passive cooling; self-recovery mechanism for automatic resume after outages or anomalies.
