Understanding the Enhanced Anti-Interference Capabilities of DJI Mavic 3 and Solutions for Drone Interferers
The DJI Mavic 3 drone from DJI has been on the market for some time now, and recently, a customer approached us with a query. They noticed that their previously purchased and installed drone interferers seemed to have a less noticeable effect on the new DJI Mavic 3 drone, particularly in terms of repelling and forcing it to land. They wanted to understand the reason behind this and explore potential solutions. This article aims to shed light on the matter by analyzing the enhanced anti-interference capabilities of the DJI Mavic 3 and proposing a solution for drone interferers.
Enhanced Anti-Interference Capabilities of DJI Mavic 3
DJI, as a company, consistently improves and upgrades the anti-interference capabilities of their new drone models. Upon detailed analysis and understanding, it is evident that the DJI Mavic 3 drone utilizes the commonly used 2.4G and 5.8G frequency bands for remote flight control and image transmission. However, DJI has further strengthened the frequency hopping anti-interference capabilities of the DJI Mavic 3 compared to previous models. Additionally, a notable change in the navigation positioning module of the DJI Mavic 3 is the addition of the BeiDou positioning module.
Explanation for Weakened Functionality of Drone Interferers
To understand the reason behind the reduced functionality of drone interferers in repelling and forcing the DJI Mavic 3 to land, it is important to consider the frequency coverage of the built-in GPS navigation interference module of previous drone interferers. It is possible that the frequency bandwidth was not adequately reserved to fully affect the frequencies used by the BeiDou navigation system. From a frequency division standard perspective, two frequency bands of the BeiDou navigation system are located within the starting and ending regions of the GPS 1.5G frequency band.
Solution for Drone Interferers
Fortunately, resolving this issue is not difficult or complex. Our recommendation is to send the existing drone interferers back to the manufacturer for reconfiguration of the GPS frequency transmission. By adjusting the emission frequency within the GPS frequency band, the interferers can effectively target the frequencies used by the BeiDou navigation system, thereby restoring their functionality in repelling and forcing the DJI Mavic 3 to land.
The DJI Mavic 3 drone boasts enhanced anti-interference capabilities, including improved frequency hopping resistance. The addition of the BeiDou positioning module in its navigation system sets it apart from previous models. Consequently, drone interferers designed for earlier models may exhibit weakened functionality in repelling and forcing the DJI Mavic 3 to land. However, by reconfiguring the GPS frequency transmission of the interferers, their effectiveness can be restored. DJI’s continuous efforts to optimize and upgrade the anti-interference capabilities of their drones ensure a better user experience and improved performance in various scenarios.
