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

Specifications

Compatibility

• DJI Matrice 400 for maximum base-station range (FCC 40 km)
• DJI Matrice 4 Series (Matrice 4E and Matrice 4T) for base station and relay station modes
• DJI Matrice 4D Series (Matrice 4D and Matrice 4TD), including use with DJI Dock 3
• DJI Matrice 350 RTK and Matrice 300 RTK for base station RTK corrections
• DJI Matrice 30 Series for base station RTK corrections
• DJI Mavic 3 Enterprise Series for base station RTK corrections

Who this is for

• Surveyors and mapping crews who want a single device that handles corrections for the drone and ground control for the site
• Inspection and public-safety teams flying in obstructed or urban environments where relay mode noticeably extends usable range
• Dock 3 operators who need a PoE-capable relay to keep docked aircraft online at the edge of coverage (via the Relay Fixed Deployment Version)
• Agencies and contractors already running Matrice 350 RTK, Matrice 4 Series, Matrice 400, or Mavic 3 Enterprise fleets who want to add or upgrade their RTK workflow

What's included
