QGroundControl NTRIP Setup: PX4 Drone RTK

Send RTKdata NTRIP corrections to any PX4 drone with QGroundControl. NTRIP/RTK settings, host address, server port 2101, AUTO mount point, and RTK Fixed verification.

QGroundControl (QGC) is the ground control station for PX4-based drones. Its built-in NTRIP client streams RTK corrections from a caster like RTKdata.com to the vehicle, so any PX4 aircraft with an RTK-capable GNSS receiver can reach centimeter-level accuracy. One setup covers every PX4 vehicle.

Requirements

  • QGroundControl (current version) on the ground station

  • PX4 vehicle with an RTK-capable GNSS receiver

  • Telemetry link between QGC and the vehicle

  • Internet on the ground station

  • Active RTKdata.com account with RTK credentials

Step-by-step setup

1

Open the NTRIP / RTK settings

In QGroundControl, open Application Settings → NTRIP / RTK.

2

Enter your RTKdata caster details

Fill in the fields using your region's host:

  • Host address: rtk.rtkdata.com (IP fallback 13.56.117.10)

  • Server port: 2101

  • Username / Password: From RTK Credentials in the dashboard (username starts with rtk)

  • Mount Point: AUTO (ALL CAPS) — or use Browse to pick from the source table

  • Use TLS encryption: off

  • RTCM Message Filter: leave empty (forward all)

Alternative mountpoints for a specific datum: AUTO_WGS84, AUTO_ITRF2020, AUTO_ITRF2014.

3

Connect and verify RTK Fix

QGC connects to the caster and forwards RTCM corrections to the vehicle. Watch the GPS status progress 3D Fix → RTK Float → RTK Fixed.

Vertical reference (heights)

RTKdata delivers ellipsoidal heights (WGS 84 ellipsoid). Apply a geoid model in your processing if you need orthometric heights.

Troubleshooting

Problem
Cause
Fix

Connects but stays on Float

Vehicle position (GGA) not reaching the caster

Ensure the vehicle has a 3D fix so QGC can report position; update QGC to a current version

Connection fails immediately

TLS enabled

Turn Use TLS encryption off — RTKdata uses a plain caster on 2101

Authentication fails

Wrong credentials

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

Mount point empty in Browse

Source table not loaded

Re-open the settings to refresh, then select AUTO

Tips

  • One page, every PX4 vehicle.

  • Leave the RTCM Message Filter empty so all correction messages are forwarded.

  • TLS off, port 2101, mountpoint AUTO in ALL CAPS.
