GPS interference on the Bulgarian Black Sea coast

In recent weeks, there have been increasing reports of GPS/GNSS interference in the Bulgarian Black Sea region. Such interference can affect drone navigation and functions such as position hold, Return to Home (RTH), and precise location determination.

If you are planning a flight by the sea, we recommend:

• Check the conditions before takeoff.
• Monitor satellite counts and alerts in DJI Fly.
• Do not rely entirely on automatic modes when GPS behavior is questionable.
• Fly with caution and maintain constant visual contact with the drone.

On the map, you can select a specific date and check if there are any disruptions reported in the area you intend to fly.

A safe flight starts before takeoff. Check the conditions, plan carefully, and don't underestimate navigational warnings.
