GPS

The GPS tab configures GPS module settings and shows live GPS status (fix type, satellite count, position, a live map).

Module setup

Protocol selects how the GPS module talks to the flight controller: NMEA or UBLOX over a serial port, MSP (a companion device relaying GPS over MSP), or FBUS (GPS position piggybacked on an FrSky FBUS link -- in which case the satellite signal-strength panel and baud/config options below don't apply, since FBUS carries an already-processed fix rather than raw module output).

For NMEA/UBLOX modules, Auto Baud and Auto Config let the Configurator detect the module's baud rate and push its own configuration automatically -- leave both on unless you have a reason to manage the module yourself. U-blox modules specifically also expose a Ground Assistance Type (SBAS region -- EGNOS/WAAS/MSAS/GAGAN/auto/none) and a Galileo toggle (swaps the QZSS constellation for Galileo, since a module only tracks so many constellations at once).

Home Point Once controls when the home point is captured: off (the default) resets it on every arm, so the point always matches your most recent takeoff; on captures it only on the very first arm after power-up, useful if you deliberately arm/disarm on the bench before walking to your actual takeoff spot.
