The D-RTK 3 Multifunctional GNSS Station features high-performance antennas and receiver modules that track and process data from all major global satellite navigation systems. It supports multiple data transmission links, enabling it to operate as a base station that provides centimeter-level positioning for multiple drones simultaneously or to extend drone operational ranges in relay mode.

Additionally, the rover station mode, integrated with the DJI Enterprise app and DJI Terra, delivers a complete solution for high-precision aerial surveying, ensuring secure and accurate operations.

Multiple Modes, Versatile Control

Base Station Mode:

Supports Simultaneous Operation of Multiple Models

The D-RTK 3 supports the new O4 Enterprise video transmission system, featuring four external directional antennas that deliver stable 15 km video transmission in base station broadcast mode.

This ensures reliable signals in all directions. With the D-RTK 3 Multifunctional Station, operators can easily set up a single unit without additional configuration, allowing multiple drones to connect to the base station and receive centimeter-level positioning.

Relay Station Mode:

Break Through Limitations

Activate Relay Station Mode on the D-RTK 3 and install it in elevated locations within areas that have significant signal obstructions, such as urban environments or valleys. This setup enhances video transmission distances and extends the Matrice 4 series’ operational range up to 25 kilometers.

The D-RTK 3 features obstruction sensing for the Matrice 4 Series, providing real-time analysis of obstructions and signal quality between the relay station, remote controller, and drone. This allows operators to adjust the drone’s position using prompts from the remote controller, ensuring optimal communication quality.

Rover Station Mode:

Flexible and Efficient

In addition to functioning as a base station, the D-RTK 3 can operate as a rover station to collect control point coordinates. This enhances the accuracy and precision of UAV aerial surveys.

Effortless High-Precision Positioning

Enhanced Performance for Superior Accuracy

The D-RTK 3 is equipped with an air dielectric antenna featuring a specialized filtering design that effectively tracks low-elevation satellites. Its antenna phase-center accuracy remains within millimeters, providing exceptional resistance to multipath interference and ensuring high-precision positioning even in complex environments.

With its integrated receiver module, the D-RTK 3 accesses satellite data from five major global satellite systems across nineteen frequency points. Compared to traditional network RTK solutions, the D-RTK 3 delivers more accurate and stable positioning results, even when facing ionospheric disturbances.

Standalone Precise Point Positioning (PPP)

The D-RTK 3 utilizes DJI’s proprietary PPP (Precise Point Positioning) technology, enabling satellite-based auto convergence*. This delivers free decimeter-level positioning accuracy even in challenging network conditions.

*Currently supports BeiDou PPP-B2b only.

Network High-Precision Calibration

The D-RTK 3 receives RTCM data to automatically obtain coordinates and correct positions via the network. When used outdoors, it delivers centimeter-level precision positioning without the need to pre-measure the setup point location.

A DJI Integrated Mapping Solution

New DJI Enterprise App

Supports Ground Control Point (GCP) Setup and Tilt Compensation

Download the new DJI Enterprise app on your Android device to measure ground control point coordinates without the need for third-party tools. When paired with DJI drones that support RTK, the DJI solution enables a complete and efficient high-precision surveying workflow.

The D-RTK 3 features a built-in high-precision inertial measurement unit, allowing you to measure control points by simply holding the pole at an angle—no tripod or perfectly vertical base station required. This significantly boosts operational efficiency in complex measurement environments.

Supports Projection Coordinate Conversion

The new DJI Enterprise app includes a comprehensive projection coordinate database, enabling the direct output of planar coordinates. This feature streamlines your workflow by allowing seamless conversion and integration of coordinate data without the need for additional software.

Compatible with DJI Terra for Efficient Data Processing

One-Click Import: Time-Saving and Effortless

Export rover measurement results as control point files directly through the DJI Enterprise app and import them into DJI Terra without any format adjustments. DJI Terra’s powerful algorithms ensure high-precision results are generated easily, streamlining your data processing workflow.

Supports Local PPK

D-RTK 3 records raw satellite observations, enabling local PPK (Post-Processed Kinematic) calculations. When imported into DJI Terra version 4.4 or later alongside data from the Matrice 4E, local PPK can be performed with a single click, enhancing accuracy and efficiency in your surveying projects.
