What is D‑RTK 3

• The D‑RTK 3 is a multifunctional GNSS base / relay / rover station from DJI — designed to provide high-precision positioning and data transmission support for enterprise drones.

• It works not only as a traditional RTK base station (for centimeter‑level positioning), but also as a video/signal relay (extending drone‑controller / drone‑dock range) and as a mobile rover (for ground control points in mapping, or survey tasks) when needed.

Key Specs & Performance

• GNSS Support & Positioning Accuracy: Handles multiple satellite systems (GPS, GLONASS, Galileo, BeiDou, etc.) across many frequencies.

• RTK Accuracy (Rover mode, static survey): ~ 0.8 cm horizontal + 1 ppm, 1.5 cm vertical + 1 ppm (RMS).

• Support for PPK / PPP workflows: Can record raw observation data for post‑processing, useful when real‑time corrections aren’t available.

• Video / Data Transmission (when used as relay or base station): Uses O4 Enterprise transmission system — allows drones to maintain stable links over extended distances / in challenging environments.

• Transmission / Relay Range (unobstructed):

  • Base Station → Aircraft: up to ~ 15 km (depending on region / regulations)

  • Relay Station Mode (aircraft ↔ relay): up to ~ 25–40 km (in ideal conditions) depending on aircraft & region.

• Physical robustness: Rated IP67 (waterproof / dustproof), operating temperature from –20 °C to +55 °C — suitable for field work, even harsh environments.
