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

Option Description
Protocol The 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 Config Automatically configures the GPS settings; it is recommended to this enabled. Requires AlphaFly 4.5 or newer for M10 GPS modules.
    Use Galileo Enable this if you want to use Galileo satellites; for most users, this should be enabled.
    Set Главная Point Once When 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 Type The type of ground assistance to use; this should be set depending on your region.
    Magnetometer Declination The declination of the magnetometer; only useful if you are using a GPS module with a magnetometer.
