DJI D-RTK 3 Multifunctional Station — Maximized Precision, Enhanced Range
The new D-RTK 3 Multifunctional Station integrates high-performance antennas and receiver modules capable of tracking and resolving data from major global satellite navigation systems. It supports multiple data transmission links and can analyze device position and orientation through its built-in high-performance inertial measurement unit. With these outstanding features, it can serve as a base station to provide centimeter-level positioning for multiple drones simultaneously, or extend the operational range of drones in relay station mode. Additionally, the new rover station mode, combined with the DJI Enterprise app and DJI Terra, provides a comprehensive solution for high-precision aerial surveying applications, ensuring a secure and accurate operation.

Multiple Modes, Versatile Control
Base Station Mode — Anchor Multiple Aircraft at Once
Set up a single D-RTK 3 as a base station and provide centimeter-level RTK positioning to multiple drones simultaneously. With network RTK calibration the D-RTK 3 reaches 1.0 cm + 1 ppm horizontal and 3.0 cm + 1 ppm vertical accuracy. The O4 Enterprise transmission system with four directional antennas delivers a stable 40 km link to the Matrice 400 and other supported platforms, locking all operations to a single trusted reference point. No additional configuration needed — position multiple aircraft types at once.
Relay Station Mode — Extend Range 3–5x Through Obstacles
Deploy the D-RTK 3 on a rooftop, mast or tower and it becomes a relay between the aircraft and the remote controller or DJI Dock 3. In urban canyons or valleys, it delivers a 3x to 5x performance boost — and 1x to 3x improvement through trees and lighter obstruction. The D-RTK 3 also supports real-time obstruction sensing with Matrice 4 Series platforms, so operators know signal quality between the relay, controller and aircraft and can reposition the aircraft for optimal communication. The standalone D-RTK 3 Relay Fixed Deployment Version enables always-on operation with PoE power from DJI Dock 3 or third-party supplies, rated -30°C to 55°C, with lightning protection and IP67 durability.
Rover Station Mode — Collect Ground Control Points with Tilt Compensation
Mount the D-RTK 3 on the self-locking survey pole and it becomes a high-precision handheld rover. RTK accuracy reaches 0.8 cm + 1 ppm horizontal and 1.5 cm + 1 ppm vertical. The built-in IMU enables tilt survey across 0° to 60° — capture control points without a tripod or the need to keep the pole perfectly vertical. Export results to DJI Terra for seamless aerial-ground integration and high-precision mapping workflows.
High-Performance GNSS and Positioning
Five GNSS Systems, Centimetre-Level Accuracy
The D-RTK 3 tracks five major satellite navigation systems (GPS, BeiDou, Galileo, GLONASS, QZSS) across nineteen frequency points. An air-dielectric antenna with filtering design and millimeter-level phase-center accuracy resists multipath interference and delivers stable positioning even in complex urban environments. Initialization reliability exceeds 99.9%. The unit supports standalone PPP with BeiDou B2b and Galileo HAS corrections for decimeter-level precision without a base station, and network RTK for centimeter-level accuracy in real time.

Integrated with DJI Enterprise App and DJI Terra
Install the DJI Enterprise app on Android to measure ground control point (GCP) coordinates without third-party tools. The built-in IMU lets you capture points with the pole held at an angle — no tripod required. Export rover measurements directly to DJI Terra for one-click processing, or log raw observation data for local post-processed kinematic (PPK) computation. Supported platforms: DJI Matrice 400, Matrice 4E/4T, Matrice 4D/4TD, Matrice 3D/3TD, Matrice 300/350 RTK, FlyCart 100, Mavic 3 Enterprise Series, Matrice 30 Series, and professional/agricultural models. The Fixed Deployment Version also supports DJI Dock 3 and external PoE power for always-on relay operations.
Ground Control Points with Tilt Compensation
Install the DJI Enterprise app on an Android device and measure ground control point coordinates directly — no third-party software required. The built-in IMU enables tilt compensation across 0° to 60°, so you capture accurate control points without keeping the survey pole perfectly vertical.
One-Click Import into DJI Terra
Export rover measurement results as control point files and import them into DJI Terra in a single step — no manual data entry. Combine ground control points with aerial data for fast, high-precision mapping and reconstruction.
Application Scenarios
Topographic and cadastral survey, construction and earthwork, mining survey, power-line and infrastructure inspection, precision agriculture and forestry, emergency response and disaster survey, and extended-range or beyond-line-of-sight operations with DJI Dock 3.
