General Settings (Settings View)

The general settings (SettingsView > General Settings) are the main place for application-level configuration. Settable values include: display units, autoconnection devices, video display and storage, RTK GPS, brand image, and other miscellaneous settings.

Values are settable even if no vehicle is connected. Settings that require a vehicle restart are indicated in the UI.

AutoConnect to the following devices

This section defines the set of devices to which QGroundControl will auto-connect.

Device autoconnect settings

Settings include:

  • Pixhawk: Autoconnect to Pixhawk-series device
  • SiK Radio: Autoconnect to SiK (Telemetry) radio
  • PX4 Flow: Autoconnect to PX4Flow device
  • LibrePilot: Autoconnect to Libre Pilot autopilot
  • UDP: Autoconnect to UDP
  • RTK GPS: Autoconnect to RTK GPS device
  • NMEA GPS Device: Autoconnect to an external GPS device to get ground station position (see below)

Ground Station Location (NMEA GPS Device)

QGroundControl will automatically use an internal GPS to display its own location on the map with a purple Q icon (if the GPS provides a heading, this will be also indicated by the icon). It may also use the GPS as a location source for Follow Me Mode - currently supported on PX4 Multicopters only.

You can also configure QGC to connect to an external GPS device via a serial or UDP port. The GPS device must support the ASCII NMEA format - this is normally the case.

A higher quality external GPS system may be useful even if the ground station has internal GPS support.

Use the NMEA GPS Device drop-down selector to manually select the GPS device and other options:

  • USB connection:

    NMEA GPS Device - Serial

    • NMEA GPS Device: Serial
    • NMEA GPS Baudrate: The baudrate for the serial port

    To troubleshoot serial GPS problems: Disable RTK GPS auto connection, close QGroundControl, reconnect your GPS, and open QGC.

  • Network connection:

    NMEA GPS Device - UDP

    • NMEA GPS Device: UDP Port.
    • NMEA Stream UDP Port: The UDP port on which QGC will listen for NMEA data (QGC binds the port as a server)

RTK GPS

This section allows you to specify the RTK GPS "Survey-in" settings, to save and reuse the result of a Survey-In operation, or to directly enter any other known position for the base station.

RTK GPS Settings

The Survey-In process is a startup procedure required by RTK GPS systems to get an accurate estimate of the base station position. The process takes measurements over time, leading to increasing position accuracy. Both of the setting conditions must met for the Survey-in process to complete. For more information see RTK GPS (PX4 docs) and GPS- How it works (ArduPilot docs).

In order to save and reuse a base position (because Survey-In is time consuming!) perform Survey-In once, select Use Specified Base Position and press Save Current Base Position to copy in the values for the last survey. The values will then persist across QGC reboots until they are changed.

The settings are:

  • Perform Survey-In
    • Survey-in accuracy (U-blox only): The minimum position accuracy for the RTK Survey-In process to complete.
    • Minimum observation duration: The minimum time that will be taken for the RTK Survey-in process.
  • Use Specified Base Position
    • Base Position Latitude: Latitude of fixed RTK base station.
    • Base Position Longitude: Longitude of fixed RTK base station.
    • Base Position Alt (WGS94): Altitude of fixed RTK base station.
    • Base Position Accuracy: Accuracy of base station position information.
    • Save Current Base Position (button): Press to copy settings from the last Survey-In operation to the Use Specified Base Position fields above.

ADSB Server

ADSB_Server Settings

The settings are:

  • Connect to ADSB SBS server: Check to connect to ADSB server on startup.
  • Host address: Host address of ADSB server
  • Server port: Port of ADSB server

QGC can consume ADSB messages in SBS format from a remote or local server (at the specified IP address/port) and display detected vehicles on the Fly View map.

One way to get ADSB information from nearby vehicles is to use dump1090 to serve the data from a connected RTL-SDR dongle to QGC. The steps are:

  1. Get an RTL-SDR dongle (and antenna) and attach it to your ground station computer (you may need to find compatible drivers for your OS).
  2. Install dump1090 on your OS (either pre-built or build from source).
  3. Run dump1090 --net to start broadcasting messages for detected vehicles on TCP localhost port 30003 (127.0.0.1:30003).
  4. Enter the server (127.0.0.1) and port (30003) address in the QGC settings above.
  5. Restart QGC to start seeing local vehicles on the map.

Video

The Video section is used to define the source and connection settings for video that will be displayed in Fly View.

Video settings

The settings are:

  • Video Source: Video Stream Disabled | RTSP Video Stream | UDP h.264 Video Stream | UDP h.265 Video Stream | TCP-MPEG2 Video Stream | MPEG-TS (h.264) Video Stream | Integrated Camera

    If no video source is specified then no other video or video recording settings will be displayed (above we see the settings when UDP source is selected).

  • URL/Port: Connection type-specific stream address (may be port or URL).
  • Aspect Ratio: Aspect ratio for scaling video in video widget (set to 0.0 to ignore scaling)
  • Disabled When Disarmed: Disable video feed when vehicle is disarmed.
  • Low Latency Mode: Enabling low latency mode reduces the video stream latency, but may cause frame loss and choppy video (especially with a poor network connection).

Video Recording

The Video Recording section is used to specify the file format and maximum allocated file storage for storing video. Videos are saved to a sub-directory ("Video") of the Application Load/Save Path.

Video - without auto deletion

Video - auto deletion

The settings are:

  • Auto-Delete Files: If checked, files are auto deleted when the specified amount of storage is used.
  • Max Storage Usage: Maximum video file storage before video files are auto deleted.
  • Video File Format: File format for the saved video recording: mkv, mov, mp4.

Brand Image

This setting specifies the brand image used for indoor/outdoor colour schemes.

The brand image is displayed in place of the icon for the connected autopilot in the top right corner of the toolbar. It is provided so that users can easily create screen/video captures that include a company logo/branding.

Brand Image
