DJI Dock 3 / Matrice 4D RTK Setup: FlightHub 2

Connect DJI Dock 3 and the Matrice 4D to RTKdata NTRIP corrections via Custom Network RTK in FlightHub 2. Host, port, and ALL CAPS AUTO mountpoint for centimeter RTK.

Connect the DJI Dock 3 and its Matrice 4D / 4TD aircraft to RTKdata.com's NTRIP correction service for centimeter-level positioning. The Matrice 4D uses the same DJI NTRIP client as the Matrice 4 Enterprise line, configured for the docked (drone-in-a-box) workflow through DJI FlightHub 2.

For the handheld Matrice 4 Enterprise (non-docked) flow, see DJI Matrice 4 Enterprise RTK. This page covers the docked Dock 3 / M4D workflow configured in FlightHub 2.

Requirements

  • System: DJI Dock 3 with a Matrice 4D / 4TD aircraft

  • Platform: DJI FlightHub 2 (cloud) to manage the dock and its RTK source

  • Internet: The dock's wired/cellular connection

  • RTKdata account: Active subscription with NTRIP credentials

Step-by-step setup

1

Open the dock's RTK settings in FlightHub 2

In DJI FlightHub 2, open the dock's settings and find the RTK Service Type. Select Custom Network RTK (third-party NTRIP).

2

Enter NTRIP connection settings

Select your region and enter the corresponding server details:

  • Host (domain): rtk.rtkdata.com

  • Host (IP fallback): 13.56.117.10

  • Port: 2101

  • Username / Password: From RTK Credentials in the internal dashboard (not website login)

  • Mountpoint (ALL CAPS): AUTO (recommended) — or AUTO_WGS84, AUTO_ITRF2020, AUTO_ITRF2014

DJI requires the mountpoint in ALL CAPS (AUTO). Lowercase or local CRS names will result in no corrections.

The RTKdata caster uses your GGA position to select the nearest reference station and stream single-baseline RTCM3 corrections. RTKdata is single-baseline and location-keyed — it is not a VRS service. The DJI NTRIP client sends GGA automatically once the aircraft has a satellite fix. See NTRIP & GGA Essentials.

3

Apply and verify Fix

Save the settings. On the next mission, confirm the aircraft reaches RTK FIX before the dock releases it for the flight.

Vertical reference (heights)

RTK corrections deliver ellipsoidal heights (height above the WGS 84 ellipsoid), not orthometric heights. Apply a geoid model in post-processing if you need orthometric heights.

Troubleshooting

Problem
Cause
Fix

No corrections

Wrong RTK Service Type

Select Custom Network RTK in FlightHub 2, not DJI's own network

Mountpoint error

Lowercase mountpoint

Enter AUTO in ALL CAPS

Authentication fails

Wrong credentials

Re-enter username/password from the RTKdata dashboard (username starts with rtk)

Stuck on Float

Aircraft has no satellite fix yet

Allow the aircraft to acquire satellites under open sky

Tips

  • Same DJI NTRIP client as the Matrice 4 Enterprise — the correction behavior is identical, just configured in FlightHub 2 for the dock.

  • ALL CAPS AUTO is mandatory.

  • For the handheld M4 Enterprise, use the DJI Matrice 4 Enterprise RTK guide instead.
