The DJI D-RTK 3 Multifunctional Station is a high-precision GNSS station that delivers centimetre-level positioning for DJI enterprise drones and professional survey workflows. A single portable unit operates in three modes: Base Station, Relay Station and Rover Station. For mining, security, utilities, energy, oil and gas, municipal and infrastructure teams in South Africa, it provides reliable RTK corrections, extended video transmission relay and ground control point collection from one rugged, IP67-rated device. This is a positioning and relay accessory, not an aircraft and not a payload camera.
Two hardware variants exist in the D-RTK 3 family: this portable Multifunctional Station and the separate D-RTK 3 Relay Fixed Deployment Version (PoE, fixed install). This page covers the portable Multifunctional Station. Contact GoUAV if you need the fixed deployment variant.
Why choose the D-RTK 3 Multifunctional Station
Centimetre-level RTK
RTK fixed survey accuracy of horizontal 0.8 cm (RMS) + 1 ppm and vertical 1.5 cm (RMS) + 1 ppm in Rover Station Mode, under favourable conditions.
Three modes in one
Switch between Base Station, Relay Station and Rover Station Mode to support multi-drone correction, extended video relay and control point collection.
Built for the field
IP67 protection, 2 m drop resistance with pole, operation from -20 C to 55 C and a 6500 mAh battery for extended time on site.
Three operating modes
Base Station Mode
Broadcasts RTK corrections so multiple drones receive centimetre-level positioning from one station at the same time. Network RTK calibration reference accuracy is horizontal 1.0 cm (RMS) + 1 ppm and vertical 3.0 cm (RMS) + 1 ppm. Single point accuracy without calibration is horizontal 1.5 m (RMS) and vertical 3.0 m (RMS). Initialization reliability is greater than 99.9 percent.
Relay Station Mode
Placed at height, the station extends O4 Enterprise video transmission range and supports obstruction sensing with the Matrice 4 Series. Relay Station Mode uses O4 at 2.4, 5.2 and 5.8 GHz and consumes 14.5 W, with roughly 4 hours of battery operation at normal temperature.
Rover Station Mode
Collects control point and ground control point coordinates with tilt compensation for survey workflows. RTK tilt survey supports an angle range of 0 to 60 degrees, with horizontal accuracy of 8 mm + 0.7 mm per degree of tilt, and accuracy better than 2 cm within 30 degrees of tilt. Connects to mobile devices over BLE 2.4 GHz and Bluetooth 5.1 within approximately 30 m.
Positioning performance
The D-RTK 3 tracks five major satellite systems across nineteen frequency points: GPS (L1C/A, L2C, L5), BeiDou (B1I, B2I, B3I, B1C, B2a, B2b), Galileo (E1, E5a, E5b, E6), GLONASS (L1, L2) and QZSS (L1C/A, L2C, L5), with L-Band support in later versions.
Satellite-based precise point positioning (PPP) supports BDS B2b, Galileo E6 and L-Band, with a convergence time of 20 minutes and reference accuracy of horizontal 30 cm (RMS) and vertical 40 cm (RMS). Differential data is recorded as RTCM 3.2 raw observation in DAT format, with RTCM v3.0 to v3.3 and MSM4 to MS7 supported for rover and calibration use.
Streamlined survey workflow
The DJI Enterprise app for Android handles ground control point setup with tilt compensation, plus mainstream projection coordinate conversion for direct planar output, so no third-party tools are needed for control point measurement. In DJI Terra v4.4 and above, rover measurement results export as control point files and import directly for local PPK processing, enabling one-click local PPK with aircraft data.

Accuracy and transmission figures are laboratory and field reference measurements under favourable conditions: unobstructed line of sight, low interference and good satellite distribution. Real results depend on environment, interference, multipath and firmware. The 40 km base-station range applies only to the DJI Matrice 400 under FCC rules; other aircraft are limited to the lower figures shown. No maximum is an unconditional guarantee.

Frequently asked questions
Is the D-RTK 3 an aircraft or a camera?
No. It is a high-precision GNSS base, relay and rover station accessory. It provides positioning corrections, video transmission relay and control point collection for compatible DJI drones and survey workflows.
How accurate is it?
In Rover Station Mode, RTK fixed survey reference accuracy is horizontal 0.8 cm (RMS) + 1 ppm and vertical 1.5 cm (RMS) + 1 ppm. These are reference figures measured under favourable conditions and real results vary with environment and interference.
Can it support more than one drone at a time?
Yes. In Base Station Mode it broadcasts RTK corrections so multiple compatible drones can receive centimetre-level positioning from one station simultaneously.
What is the difference from the Fixed Deployment Version?
This portable Multifunctional Station runs on its own battery with USB Type-C charging and IP67 protection. The D-RTK 3 Relay Fixed Deployment Version is a PoE fixed install variant. Contact GoUAV if you need the fixed version.
Does the 40 km range apply to any drone?
No. The 40 km base-station range applies only to the DJI Matrice 400 under FCC rules. Other aircraft and other regulatory domains are limited to the lower figures listed in the specifications.
What software do I need for surveys?
The DJI Enterprise app for Android handles ground control point setup and coordinate conversion. DJI Terra v4.4 and above imports rover control point files for one-click local PPK processing with aircraft data.
