GPS Configuration​

Here’s the revised table with the protocol options combined:

OptionDescription
ProtocolThe GPS protocol to use.
  • UBLOX - The most common GPS protocol; most GPS modules use this protocol.
  • NMEA - Use this for GPS modules that don't support UBLOX.
  • MSP - Use this for GPS modules that use MSP protocol.
    • Auto ConfigAutomatically configures the GPS settings; it is recommended to keep this enabled. Requires Betaflight 4.5 or newer for M10 GPS modules.
    Use GalileoEnable this if you want to use Galileo satellites; for most users, this should be enabled.
    Set Home Point OnceWhen enabled, only the first arm after the battery is connected will be used as the home point; if not enabled, every time the quad is armed, the home point will be updated.
    Ground Assistance TypeThe type of ground assistance to use; this should be set depending on your region.
    Magnetometer DeclinationThe declination of the magnetometer; only useful if you are using a GPS module with a magnetometer.

    GPS Info​

    OptionDescription
    3D FixWhether the GPS has a 3D fix; required for GPS Rescue and showing GPS coordinates in the OSD.
    SatellitesThe number of satellites the GPS is connected to.
    AltitudeThe altitude the GPS is reporting.
    SpeedThe speed the GPS is reporting.
    Heading IMU / GPSThe heading the GPS is reporting.
    Current Latitude / LongitudeThe current latitude and longitude the GPS is reporting.
    Dist to homeThe distance to the home point.
    Positional PDOPThe current Dilution of Precision; a lower value is better.

    GPS Signal Strength​

    In this section you can see the signal strength of the GPS satellites.

    OptionDescription
    Gnss IDThe GNSS ID of the satellite.
    Sat IDThe Satellite ID of the satellite.
    Signal StrengthA visual representation of the signal strength of the satellite.
    StatusWhether the satellite is used for the GPS fix.
    QualityThe quality of the signal.
