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.

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

One page, every PX4 vehicle.
Leave the RTCM Message Filter empty so all correction messages are forwarded.
