Features of D-RTK 3 Multifunctional Station
Achieve centimeter-level precision and robust positioning performance with the DJI D-RTK 2 Mobile Station, the ultimate GNSS receiver for commercial drone operations. Built for versatility and accuracy, it ensures your flights are safe, reliable, and repeatable—even in the most complex environments.
D-RTK 3 Relay Fixed Deployment Version features highly redundant and reliable hardware and software design, significantly reducing maintenance costs. Equipped with lightning surge protection and an IP67 rating, it operates stably in temperatures ranging from -30°C to 50°C. Once deployed, it can continuously perform outdoor operations with minimal intervention.
D-RTK 3 uses an air dielectric antenna with a filtering design, effectively tracking low-elevation satellites. The antenna phase-center accuracy is maintained within millimeter level, ensuring strong resistance to multipath interference and enabling high-precision positioning even in complex environments.
With its built-in receiver module, D-RTK 3 can receive satellite data from five major satellite systems across nineteen frequency points. Compared to network RTK, D-RTK 3 provides more accurate and stable positioning results under ionospheric effects.
D-RTK 3 supports the new O4 Enterprise video transmission system. Equipped with four external directional antennas, it achieves a maximum RTK coverage range of 15 km [1] in base station mode while ensuring stable signals in all directions. Operators only need to set up one D-RTK 3 Multifunctional Station without additional configuration, allowing multiple drones to connect to the base station and access centimeter-level positioning.

Adaptable to Various Environments
The Fixed Deployment Version offers outdoor maintenance-free operation and adaptability to various environments. It can be installed on towers, utility poles, parapet walls, and other vertical structures, meeting diverse scenario requirements. Additionally, it supports power supply from DJI Dock 3 or third-party external PoE sources, enabling long-distance deployments.
Standalone Precise Point Positioning (PPP)
D-RTK 3 utilizes DJI’s proprietary PPP solution, enabling satellite-based auto convergence*. It provides free decimeter-level positioning even in challenging network conditions.
Network High-Precision Calibration
D-RTK 3 can receive RTCM data and automatically obtain coordinates and correct positions through the network. When used outdoors, it can achieve centimeter-level precision positioning without pre-measuring the setup point location.
