QGroundControl NTRIP Setup: PX4 Drone RTK

Send RTKdata NTRIP corrections to any PX4 drone in QGroundControl. NTRIP settings, host, port 2101, AUTO mount point and the RTK Fixed check.

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:

North America

• 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)

Europe

• Host address: eu.rtkdata.com (IP fallback 3.73.41.96)

• 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)

Australia

• Host address: aus.rtkdata.com (IP fallback 54.206.56.130)

• 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.

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.

RTKdata needs your position (GGA). The caster uses your GGA position to select the nearest reference station and stream single-baseline RTCM3 corrections: it is not a VRS service and sends nothing without a position. QGC must forward the vehicle's position to the caster. If you connect but stay on Float with no Fix, the position/GGA is not reaching the caster: see Troubleshooting and NTRIP & GGA Essentials.

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.
