Relay Station Mode [2] : Break Through Limitations

In urban areas, valleys, or challenging DJI Dock 3 sites with dense obstacles, simply switch the D-RTK 3 to Relay Station Mode [2] and position it at a high point, or directly set up the D-RTK 3 Relay Fixed Deployment Version. This setup enhances the video transmission range for the Matrice 4/4D series, extending operational coverage up to 25 kilometers [3].

D-RTK 3 supports obstruction sensing with the Matrice 4 Series, allowing real-time calculations of obstructions and signal quality between the relay station, the remote controller, and drone. Operators can adjust the drone’s position based on prompts from the remote controller to ensure optimal communication quality.

Base Station Mode: Supports Simultaneous Operation of Multiple Models

D-RTK 3 supports the new O4 Enterprise video transmission with four external directional antennas, enabling 15 km [1] video transmission in base station broadcast 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.

Rover Station Mode: Flexible and Efficient

Besides serving as a base station, D-RTK 3 can also be used as a rover station to collect control point coordinates, enhancing the accuracy of UAV aerial survey and improving survey precision.

Maintenance-Free Relay Fixed Deployment Version

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 Airport 3 or third-party external PoE sources, enabling long-distance deployments.

Outstanding Protection and Reliability

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.

Effortless High-Precision Positioning

Stronger Performance, More Accurate Positioning

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.

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.

* Currently supports BeiDou PPP-B2b only.

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.

DJI Integrated Mapping Solution

New DJI Enterprise App

Supports Ground Control Point (GCP) Setup and Tilt Compensation

Install the new DJI Enterprise app on an Android device to measure ground control point coordinates without third-party tools. When used with DJI drones supporting RTK, the DJI solution can efficiently complete an entire high-precision surveying workflow.

D-RTK 3 has a built-in high-precision inertial measurement unit, allowing the control point to be measured when the pole is held at an angle without a tripod or ensuring the base station is vertical, significantly improving operational efficiency in complex measurement environments.

Supports Projection Coordinate Conversion

The new DJI Enterprise app includes a mainstream projection coordinate database, allowing direct output of planar coordinates.

Compatible with DJI Terra for Efficient Data Processing

One-Click Import, Time-Saving and Effortless

Rover measurement results can be exported as control point files via the DJI Enterprise app and imported into DJI Terra without the need for additional format adjustments. With powerful algorithms, high-precision results can be easily generated.

Supports Local PPK

D-RTK 3 supports recording raw satellite observations. When imported into DJI Terra version 4.4 or above along with data from the Matrice 4E, local PPK calculations can be performed with one click.
