DJI D-RTK 3 Relay Fixed Deployment Version for Dock 3: Fixed RTK relay station for extended Dock operations

The DJI D-RTK 3 Relay Fixed Deployment Version is a dedicated relay solution designed specifically for DJI Dock 3 operations in complex or obstructed environments. Operating exclusively in relay station mode, it bridges communication gaps between aircraft and Dock 3 while simultaneously supporting high-precision RTK positioning. Powered via Power-over-Ethernet, it connects directly to Dock 3 for streamlined installation and long-term outdoor deployment. With IP67 protection, wide operating temperature tolerance, and remote relay access capability, this fixed deployment version is built for continuous, unattended operation in demanding enterprise environments.

DJI D-RTK 3 Relay Fixed Deployment Version features

  • Relay-only operation: Designed exclusively for signal relay and RTK support.
  • Extended signal coverage: Bridges communication gaps caused by terrain and structures.
  • Centimeter-level RTK positioning: Supports high-accuracy missions with supported aircraft.
  • O4 Enterprise relay system: Enhances video and control link reliability.
  • Elevated deployment capability: Optimized for towers, rooftops, and vertical structures.
  • Direct Dock 3 integration: Connects to Dock 3 third port without additional hardware.
  • Remote relay access: Enables automatic aircraft discovery and relay connection.
  • Redundant system design: Reduces maintenance requirements for fixed installations.

Purpose-built for permanent and semi-permanent Dock 3 installations

The D-RTK 3 Relay Fixed Deployment Version is engineered for long-term outdoor installation where traditional base station placement is impractical. By operating solely in relay mode, it eliminates configuration complexity and focuses on maintaining stable communication paths between Dock 3 and deployed aircraft. Power-over-Ethernet support simplifies infrastructure planning by combining power and data through a single cable. This design allows operators to deploy Dock 3 systems in locations previously limited by terrain, buildings, or electromagnetic interference, expanding operational flexibility without increasing system complexity.

Environmental resilience and continuous outdoor operation

Designed for unattended outdoor use, the D-RTK 3 Relay Fixed Deployment Version features an IP67-rated enclosure and lightning surge protection to withstand harsh environmental conditions. DJI specifies stable operation across a temperature range of −30° to 50° C (−22° to 122° F), supporting year-round deployment in varied climates. Its maintenance-free design reduces operational overhead, allowing the relay station to remain continuously active once installed. These characteristics make it suitable for critical infrastructure monitoring, emergency response readiness, and persistent inspection operations.

Engineered for enterprise reliability and remote accessibility

The D-RTK 3 Relay Fixed Deployment Version is designed as a high-reliability infrastructure component within the DJI Dock ecosystem. Its relay station can be remotely accessed without manual button interaction, allowing nearby aircraft to automatically discover and connect to idle relay stations. Combined with redundant hardware and software design, this approach minimizes downtime and maintenance requirements. When paired with Dock 3, it enables scalable, resilient drone operations where communication reliability and positioning accuracy are critical.

The DJI D-RTK 3 Relay Fixed Deployment Version expands Dock 3 deployment possibilities through reliable relay and RTK support.
