GPS rescue

GPS rescue is a flight controller feature that uses onboard GPS to bring a drone back toward its recorded takeoff location automatically, typically triggered by a lost radio link or activated manually by the pilot when they lose visual or orientation. It is meant as a recovery option, not a routine way to end a flight.

For GPS rescue to work reliably, the drone needs a strong GPS lock recorded before takeoff, a properly configured GPS module, and correct failsafe settings tied to the feature. A weak or absent GPS lock at launch can make the whole feature unreliable exactly when it is needed most.

Pilots sometimes treat GPS rescue as though it were a guarantee that a drone can never be lost, but GPS accuracy, obstacles along the return path, and remaining battery can all affect whether a rescue actually succeeds. It is a useful backup worth configuring and testing in open, low-risk conditions, not a substitute for flying within sight and within a sensible range.
