D-RTK 3 Relay Fixed Deployment Version
D-RTK 3 Relay Fixed Deployment Version
SKU:
The DJI D-RTK 3 Relay Fixed Deployment Version is designed to enhance communication reliability for automated drone operations. By acting as a relay station between the drone and the dock, it helps maintain stable signal transmission even in complex environments.
It is an essential component for long-range and obstacle-challenged deployments.

Reliable Signal Relay
Maintain stable communication where direct connections are limited.
When buildings, terrain, or infrastructure block the signal between the drone and the dock, the relay station forwards the communication signal to ensure uninterrupted control and data transmission.
Key Benefits
• Extends operational communication range
• Reduces signal obstruction from terrain and buildings
• Improves video transmission stability
• Supports long-distance automated missions
This makes it ideal for industrial and infrastructure environments.
Designed for Automated Drone Systems
The relay station is commonly deployed as part of an automated drone ecosystem.
It works together with:
- DJI Dock 3
- DJI Matrice 4D
- DJI Matrice 4TD
By adding a relay node between the dock and the aircraft, the system can maintain stable connectivity in areas where direct communication may be unreliable.
Enhanced RTK Positioning Support
In addition to communication relay, the system also assists with RTK positioning stability.
The device can help provide more reliable positioning data, improving the accuracy of automated flight paths and mission execution.
Advantages
• Improved positioning reliability
• More accurate flight routes
• Better data consistency for mapping and inspection tasks
Built for Fixed Outdoor Deployment
The fixed deployment version is designed for long-term installation in demanding environments.
Features
• Supports permanent installation on rooftops, towers, or poles
• Stable network connection and remote management
• Weather-resistant industrial design
• Suitable for continuous 24/7 operations
Once installed, it requires minimal maintenance while providing consistent performance.
