Using GPS for altitude without a barometer in INAV is a specific configuration that allows multicopters and airplanes to utilize navigation modes even when they lack a barometric pressure sensor. While INAV historically mandated a barometer for multicopter automated altitude control, the CLI setting inav_use_gps_no_baro enables GPS-based altitude for these autonomous features.

The CLI setting set inav_use_gps_no_baro = ON enables iNav multicopters to utilize autonomous flight modes, such as NAV ALTHOLD and RTH, by substituting GPS altitude for missing barometer data The CLI setting set inav_use_gps_no_baro = ON enables
