The DJI D-RTK 3 Multifunctional Station is three surveying tools in one compact, IP67-rated unit. It works as an RTK base station delivering centimeter-level positioning to multiple DJI aircraft simultaneously, as a video transmission relay that extends O4 Enterprise range up to 40 km between the station and a Matrice 400, and as a handheld rover for measuring ground control points with fixed-survey and tilt-survey accuracy down to 0.8 cm horizontal. One mode switch, one piece of hardware, and a full GNSS stack that tracks every major satellite constellation in use today.
Base station, relay, and rover in one IP67 unit. Centimeter-accurate RTK for your Matrice, FCC-range video relay, and tilt-survey ground control on the same hardware.
Features
- Three operating modes on one device: Base Station (broadcast RTK), Relay Station (extend video and control range), and Rover Station (handheld ground-control survey)
- Centimeter-level RTK corrections streamed simultaneously to multiple compatible DJI aircraft, including the Matrice 400, Matrice 4 Series, Matrice 4D Series, Matrice 350 RTK, Matrice 30 Series, and Mavic 3 Enterprise
- Full multi-constellation GNSS: GPS (L1C/A, L2C, L5), BeiDou (B1I, B2I, B3I, B1C, B2a, B2b), Galileo (E1, E5a, E5b, E6), GLONASS (L1, L2), QZSS (L1C/A, L2C, L5), and L-Band for satellite-based PPP
- Network RTK calibration to 1.0 cm + 1 ppm horizontal, 3.0 cm + 1 ppm vertical
- Rover mode fixed-survey accuracy to 0.8 cm + 1 ppm horizontal, 1.5 cm + 1 ppm vertical
- Tilt-survey support from 0° to 60° with <2 cm accuracy within 30°, so you can measure hard-to-reach control points without leveling the pole
- Satellite-Based Precise Point Positioning with 20-minute convergence, delivering 30 cm horizontal / 40 cm vertical without needing a local base
- OcuSync 4 (O4 Enterprise) video relay mode extends aircraft-to-station range up to 25 km (FCC) and links back to the remote controller or DJI Dock 3 at up to 3 km, adding 3x to 5x range in severely obstructed environments
- IP67 dust and water ingress protection, 2 m drop-with-pole rating, and -20° to 55° C operating range for real field conditions
- Built-in 6,500 mAh LiPo battery with up to 7 hours of base station runtime, 4 hours of relay runtime, and 10 hours of rover runtime
- USB-C PD 3.0 charging and passthrough power (9-15 V) for field top-ups from any compatible power bank or adapter
- Initialization reliability greater than 99.9% for fast, confident fixes on site
Three modes, one device
| Mode | What it does | When you use it |
|---|---|---|
| Base Station (Broadcast) | Transmits RTK corrections over O4 Enterprise to one or more aircraft simultaneously | Mapping and survey flights where you need centimeter-accurate image geotags without network RTK coverage |
| Relay Station | Acts as an airborne-to-ground relay between the aircraft and the remote controller or DJI Dock 3 | BVLOS flights, obstructed environments, or dock deployments where line-of-sight to the controller is compromised |
| Rover Station | Handheld GNSS rover for fixed-survey and tilt-survey ground control point measurement | Establishing or checking GCPs before a mapping flight, or any time you need a surveying rover on site |

FAQ
What is the difference between the D-RTK 3 Multifunctional Station and the D-RTK 3 Relay Fixed Deployment Version?
The Multifunctional Station is the portable, field-ready version with an internal battery and USB-C charging. It moves with your crew and runs all three modes. The Relay Fixed Deployment Version is the permanent-install variant with PoE power and weather-hardened housing, designed to sit on a rooftop or tower near a DJI Dock 3 deployment. Most customers want the Multifunctional Station unless they are standing up a fixed dock site.
Can I use the D-RTK 3 as a base station for multiple drones at once?
Yes. In Base Station Mode the D-RTK 3 broadcasts RTK corrections to multiple compatible DJI aircraft simultaneously, so a single station can support a whole crew flying in the same area.
Does it work with my Matrice 350 RTK / Matrice 300 RTK?
Yes for RTK base-station use. The D-RTK 3 provides centimeter-level RTK corrections to the Matrice 350 RTK, Matrice 300 RTK, Matrice 4 Series, Matrice 4D Series, Matrice 400, Matrice 30 Series, and Mavic 3 Enterprise. Relay Station Mode is currently supported for the Matrice 4 Series (M4E / M4T) and DJI Dock 3.
Do I need cellular service or network RTK to use it?
No. The D-RTK 3 works as a self-contained local base station out of the box. If you want network RTK calibration for best accuracy, or satellite-based PPP without any network connection, both are supported. The Relay Fixed Deployment Version is also compatible with the DJI Cellular Dongle 2 for remote deployments.
How accurate is the tilt-survey rover mode?
Tilt-survey accuracy is better than 2 cm within 30° of tilt, degrading to approximately 8 mm plus 0.7 mm per degree at higher angles, up to a 60° limit. Tilt survey lets you measure points you could not reach with a perfectly level rod, which matters in vegetation, near structures, and on broken ground.
Is a tripod or survey pole included?
No. The tripod / survey pole is sold separately. Most surveyors already have a pole that will take the D-RTK 3's standard 5/8-11 thread mount; if you need one, we stock compatible poles and tribrachs.
Is there a warranty?
The D-RTK 3 ships with DJI's standard manufacturer warranty against defects in materials and workmanship. DJI Care Enterprise plans are available separately; contact us if you would like to bundle coverage at the time of purchase.
