Long-Endurance Drone Platform With Power-Line-Level Obstacle Sensing

DJI O4 Ground Station

Engineered for Excellence, Designed for Versatility

Wide-Area Transmission and Command for Security and Government Operations Across Africa

Fixed wide-area transmission and command system designed to maintain stable video and control links where a standard controller cannot.

12-antenna array with automatic multi-band selection for extended coverage across long distances, obstacles and demanding environments.

Connects drones and fixed cameras through DJI FlightHub 2 to create one unified operational picture for centralised monitoring and control.

Aerosmart Africa supplies, configures and supports the DJI O4 Ground Station for authorised security, government and enterprise operators across Africa.

Built for Security, Government and Critical-Infrastructure Operations

Security and government teams across Africa are responsible for long borders, dispersed critical infrastructure and wide areas of responsibility that ground patrols and standard drone controllers cannot cover continuously. The O4 Ground Station is designed for exactly this kind of persistent, wide-area work:

All deployments should be conducted by authorised operators and remain subject to national aviation, privacy and data-protection requirements.

Advanced Hardware, Robust Transmission

Advanced Hardware,
Robust Transmission.

High-performance RF unit. A high-output RF unit strengthens signal penetration and coverage, helping maintain a reliable link through dense urban obstructions. An optimised signal-to-noise ratio improves receiver sensitivity, recovering usable signals in complex electromagnetic environments.

Omnidirectional high-gain antenna. Twelve internal and external antennas with horizontal and vertical polarisation deliver omnidirectional, high-gain coverage, maintaining a stable link regardless of the aircraft's position for wide-area operations.

Automatic multi-band selection. To navigate congested RF environments, the station shifts automatically across sub-2 GHz, 2.4 GHz, 5.2 GHz, 5.8 GHz and other bands to bypass interference. Paired with the DJI Matrice 400, it can support a transmission range of up to 40 km under specified conditions; actual range depends on environment, obstruction and local frequency regulations.

5-system, 19-frequency GNSS. An integrated high-gain RTK module tracks 19 frequencies across five satellite systems, acquiring signals quickly even in urban canyons or under dense canopy and providing continuous, centimetre-level positioning to help safeguard flight operations.

Gateway Mode

Direct Network Connectivity

In Gateway Mode, the O4 Ground Station connects directly to DJI FlightHub 2 over Ethernet or the DJI Cellular Dongle 2, delivering low-latency, high-bandwidth video. This frees the station from proximity constraints and can extend coverage up to 30 km under specified conditions, allowing a command centre to observe and direct operations remotely.

Signal Map for precise deployment. After a flight, FlightHub 2 uses flight data to generate a Signal Map that highlights weak-coverage zones, helping operators position ground stations more precisely and reinforce communication links for safer flights.

Virtual Cockpit for agile control. Within coverage, operators can use the FlightHub 2 Virtual Cockpit to remotely control the aircraft, override preset routes and respond quickly to multi-point tasks—valuable for command teams directing operations from an operations room rather than the field.

Durable Design

Smart Power

Reliable Operation in Harsh Environments

An IP67 rating protects the O4 Ground Station against dust and water.

The station operates reliably from −40 °C to 55 °C, supporting continuous, unattended operation across demanding climates ranging from desert heat to highland cold.

Proprietary lightning-protection components and a grounding design meeting the EN/IEC 61643-21 Category C standard help reduce the risk of lightning damage when the station is installed at elevated locations such as hills or transmission towers.

Intelligent Power and Automatic Recovery

Fanless passive cooling and a self-recovery mechanism allow the station to resume operation automatically after power interruptions or software anomalies, reducing on-site reboots and maintenance visits.

In Gateway Mode, smart power management hibernates the station when no aircraft is connected, drawing only about 7 W on standby.

For off-grid deployments, the station can operate using DJI Power solar solutions or compatible third-party photovoltaic systems, supporting long-term deployment in remote areas.

Open Ecosystem

Integrated Visual Command

Unified visual management. The O4 Ground Station integrates up to four standard IP cameras. Using ONVIF and GB/T 28181 protocols, it streams live camera video directly into DJI FlightHub 2 and synchronises native camera alerts, such as displacement detection, with remote pan-tilt-zoom control. This gives a command centre one centralised view that combines fixed cameras and airborne feeds across a site or perimeter.

Open ESDK and airspace awareness. MQTT-based ESDK 2.0 and a Cloud API streamline integration, allowing developers and system integrators to build custom, sector-specific solutions. Through MQTT, the station can connect to third-party Remote ID or ADS-B receivers, providing real-time awareness of nearby crewed and uncrewed aircraft and helping protect the airspace around fixed deployments.

Security and Government Application Scenarios

  • Border and frontier surveillance: Wide-area, persistent monitoring across remote boundaries.
  • Critical-infrastructure protection: Monitoring for power facilities, water systems, pipelines, ports and government sites.
  • Public-safety command and control: Coordinated response using combined drone and fixed-camera feeds.
  • Disaster and emergency operations: Rapid, remotely directed situational awareness across affected areas.
  • Ports, maritime and coastal monitoring: Coverage across water and shoreline areas where ground observation is limited.
