What GNSS technologies does the DJI Mavic 4 Pro use for navigation and what benefits does it provide: The DJI Mavic 4 Pro integrates an advanced combination of GNSS systems, including GPS (United States), Galileo (European Union), BeiDou (China), and GLONASS (Russia), allowing it to operate with high precision in various regions of the world. This multi-band capability significantly increases the number of available satellites, reducing signal acquisition time and improving positional stability in urban, mountainous, or airborne flights with electromagnetic interference.
The main advantage of using multiple satellite constellations is redundancy and precision. For example, if a signal weakens due to atmospheric conditions or structural obstructions, the drone can seamlessly switch between available systems, ensuring that the flight is not compromised. This is vital for automated tasks such as subject tracking (FocusTrack), automatic return to home (RTH), or flights with predefined trajectories (Waypoint Flight).
In addition, the GNSS system is complemented by vision and infrared sensors, which provide additional positioning when satellite signals are weak, such as indoors or under dense trees. This synergy between GNSS and vision sensors allows the drone to remain stable even at low altitudes, where other models could lose positional reference and drift dangerously.
To achieve the best GNSS performance, it is recommended to always take off in open areas with good visibility to the sky, avoid interference such as telecommunications antennas or metal structures, and wait until the system indicates a sufficient number of connected satellites before initiating the flight. These practices ensure that the DJI Mavic 4 Pro maintains accurate, reliable, and safe navigation throughout its operations.
