QGC Guide (master)

RTK Corrections ​

Configure where RTK corrections come from and how they reach vehicles: the built-in NTRIP client, a local base station, or RTCM received over UDP.

Corrections Status ​

Shows the correction stream currently sent to vehicles and its data rate. The toolbar GNSS indicator also offers Connect once an NTRIP server is configured.

NTRIP Connection ​

Shows the NTRIP connection state with message and byte counters, the age of the last correction, and a Connect/Disconnect button.

NTRIP Server ​

  • Host address — NTRIP caster hostname or IP
  • Server port — NTRIP caster port (default: 2101)
  • Username — NTRIP account username
  • Password — NTRIP account password (with show/hide toggle)
  • Use TLS encryption — connect with TLS 1.2 or later
  • Accept self-signed TLS certificates — accept a caster whose certificate is self-signed. The first successful connection records that certificate; a later connection that presents a different one fails, reporting that the caster's certificate changed. Turning the option off forgets the recorded certificate. Certificates signed by a trusted authority are never recorded.

NTRIP Mountpoint ​

  • Mount Point — the NTRIP mountpoint to connect to
  • Browse — fetch available mountpoints from the server and display them in a list with format, navigation system, country, bitrate, and distance information

GGA Position Reporting ​

Network RTK (VRS) casters need the rover position. Select the position QGC reports and how often.

NTRIP Message Filter ​

  • RTCM Message Filter — whitelist of RTCM message types to forward from NTRIP (empty = forward all)

UDP RTCM Input ​

  • Enable UDP RTCM input — receive RTCM corrections over UDP, for example from another application. UDP input is used alongside NTRIP and a local base station, and incoming data is always checked to be valid RTCM.
  • UDP RTCM input port — port to listen on (default: 13320, range: 1024–65535)

UDP Forwarding ​

  • Forward corrections over UDP — forward the stream selected for vehicles to another device or application
  • UDP output address — destination IP for forwarded data
  • UDP output port — destination port for forwarded data

Correction Routing ​

  • Vehicle correction source — Highest priority sends one fresh stream to vehicles, preferring the local base station, then NTRIP, then UDP, and switches when the preferred stream stops. Selecting a source category uses only that category, without falling back to another. When several UDP senders deliver, QGC stays on the first fresh one.

Vehicles and UDP forwarding always receive the same stream.
