DJI D-RTK 3 Multifunctional Station (Base Only)

DJI D-RTK 3 Multifunctional Station: Multi-mode GNSS reference station for enterprise RTK and relay operations

The DJI D-RTK 3 Multifunctional Station is a professional-grade GNSS reference system designed to support enterprise UAV positioning, relay communications, and rover-based surveying workflows. It operates in base station, relay station, and rover station modes, allowing teams to adapt deployment based on mission requirements and site conditions.

With multi-constellation GNSS tracking, published centimeter-level RTK accuracy specifications, and O4 Enterprise relay capability, D-RTK 3 supports precise positioning and extended connectivity. Its IP67-rated enclosure, internal battery, and defined operating limits make it suitable for repeatable field deployment across demanding environments.

Key features of the DJI D-RTK 3 Multifunctional Station

• Multi-band GNSS receiver: Tracks GPS, BDS, Galileo, GLONASS, QZSS constellations.
• Base station operation: Provides RTK corrections for supported DJI aircraft fleets.
• Rover station mode: Supports survey workflows using Bluetooth-connected mobile devices.
• Network RTK calibration: Achieves centimeter-level positioning with published accuracy models.
• Fixed RTK survey accuracy: 0.8 cm horizontal plus 1 ppm specification.
• Tilt survey support: Measures points up to 60° with defined accuracy behavior.
• Satellite-based differential positioning: Supports PPP with stated convergence performance.
• RTCM compatibility: Supports RTCM v3.0–v3.3 and MSM4–MSM7 protocols.

Survey-grade accuracy with clearly defined performance envelopes

DJI publishes explicit accuracy specifications for D-RTK 3 across its supported operating modes, allowing teams to plan missions with predictable results. In base and relay station roles, uncalibrated single point accuracy is specified at 1.5 m horizontal and 3.0 m vertical RMS. Network RTK calibration improves this to 1.0 cm horizontal plus 1 ppm and 3.0 cm vertical plus 1 ppm. In rover station mode, fixed RTK survey accuracy is specified at 0.8 cm horizontal plus 1 ppm and 1.5 cm vertical plus 1 ppm, with initialization reliability exceeding 99.9 percent.

O4 Enterprise relay operation and real-world range planning

D-RTK 3 integrates O4 Enterprise transmission to support relay station deployment in environments where direct aircraft-to-controller links are obstructed. DJI publishes region-specific maximum transmission distances under unobstructed conditions, as well as reference ranges for environments with varying interference and obstruction levels. When deployed in elevated, interference-free locations, relay station mode can improve link performance by up to five times in severely obstructed terrain. These specifications allow operators to plan relay placement using realistic expectations rather than idealized laboratory conditions.
