What to do if the DJI Mavic 4 Pro loses GPS signal during flight?

What to do if the DJI Mavic 4 Pro loses GPS signal during flight: Loss of GPS signal during a flight with the DJI Mavic 4 Pro can occur in enclosed environments, areas with electromagnetic interference, or areas with partially obstructed skies. In these cases, the drone automatically switches to "ATTI mode" (Attitude Mode), a state in which it remains stabilized but without satellite positioning. This means it can no longer hold its position automatically and is affected by wind, forcing the pilot to constantly manually correct its trajectory.

During ATTI mode, the inertial sensor system maintains altitude and orientation, but experience is required to avoid accidental deviations. The pilot must maintain control of the drone, maneuver smoothly, and avoid straying too far. It is not recommended to continue automatic missions or execute RTH in this state, as these functions depend on satellite positioning. If GPS loss occurs at high altitudes, descend slowly until the signal is recovered.

The return of the GPS signal can take from a few seconds to several minutes, depending on the environment. To facilitate recovery, it is recommended to climb a few meters or change position to a clearer area. It may also help to temporarily suspend the flight in a safe location and wait for the system to register a sufficient number of satellites again. The DJI Fly app constantly displays the number of connected satellites, allowing the operator to make informed decisions.

The best way to deal with these situations is to prevent them through proper flight planning, avoiding areas with metal roofs, interference, or tall structures. It is also helpful to keep the firmware up to date, as DJI is constantly improving the mode switching algorithm. Knowing what to do in the event of a loss of GPS is essential for any responsible pilot and ensures that the DJI Mavic 4 Pro can continue to be operated safely even in the face of unforeseen events.
