The impact of GPS jammers on drone flights

In recent years, the rise of affordable, high-end drones, along with user-friendly mission planning tools, has created a favorable environment for the widespread use of drones. Drones are no longer limited to professionals and are now being applied to various fields such as measurement, inspection and volume analysis, bringing revolutionary impacts.

However, the higher the drone flies, the greater the risk if something goes wrong. GPS interference is one of the main threats to drone safety. Even a slight interruption of satellite signals can significantly reduce positioning accuracy, while severe interference can cause a complete loss of signal tracking and positioning.

Drones often encounter interference from other components installed on the aircraft, especially in confined spaces where antennas are close to electrical and electronic systems. GPS receivers on drones are particularly susceptible to external interference sources, whether intentional or unintentional. In the air, signals from GPS jammers can travel longer distances than on land.

In the case of drone inspections of large wind turbines, many countries have built windmills near roads, increasing the risk of interference from GPS jammers. For example, truck drivers can use GPS jammers to evade detection by GPS trackers on their vehicles, and car thieves can disable GPS anti-theft devices on stolen cars. The best Cell Phone Jammer and wifi jammer.

Although the chirp jammer transmits only about 10 mW, it is strong enough to interfere with GNSS signals within a radius of several hundred meters on the ground. In the air, drones are more susceptible to jamming because the range is longer and there are no obstacles such as trees and buildings to block the jamming signal.
