How accurate is the DJI Mavic 4 Pro's Return to Home system, and how does it work in different conditions: The DJI Mavic 4 Pro's Return to Home (RTH) system is designed to offer high precision through the combined use of GNSS positioning and visual sensors. When this function is activated, the drone automatically plots a route back to the takeoff point, avoiding obstacles along the way and ensuring a safe landing. The RTH system's accuracy can reach a margin of error of just one meter, provided optimal satellite availability is provided and the initial location has been correctly recorded during takeoff.
One of the great advantages of this drone's RTH system is its adaptability to different scenarios. In ideal conditions with clear skies and a good satellite signal, the drone executes a straight flight toward the home point, first ascending to a predetermined safety altitude to avoid collisions. However, if the environment presents obstacles or changes in the terrain, the visual positioning and obstacle avoidance system is activated to adjust the trajectory and ensure a safe return.
In situations where the GPS signal weakens, such as in dense urban areas or under partial roofs, the system combines visual navigation with inertial and altitude data to maintain the return course. Although accuracy may decrease slightly in these conditions, the navigation algorithm always prioritizes the safety of the drone and the continuity of the flight, choosing to stop or request manual intervention if the environment becomes too uncertain to continue automatically.
This level of return-to-home autonomy is particularly useful for photographers, surveyors, or industrial inspectors operating the drone over long distances or in areas with variable coverage. Having an accurate and reliable RTH function allows them to focus on the mission without fear of losing the drone due to loss of signal or low battery. Overall, this system brings enormous value to the DJI Mavic 4 Pro, strengthening its position as the benchmark professional drone in terms of safety and control.
