At present, the gun drone jammer has been widely used in many key military departments or important confidential places, and its built-in GPS navigation and positioning jamming module is almost a necessary standard configuration. Then the question arises: When dealing with drone defense, should the GPS navigation and positioning interference in this gun-shaped drone jammer need to be turned on? If it is not necessary to turn on or not necessary to turn on, when is the most appropriate time to turn it on?

Let's first analyze what role the GPS navigation and positioning jamming module plays in the gun-shaped drone jammer. It is easy to understand that GPS navigation and positioning interference must interfere with GPS navigation and positioning signals. Of course, the GPS navigation and positioning signals referred to here are a general term, usually including GPS, Beidou, Galileo, Grid Various satellite navigation signals such as Lonas are collectively referred to as GPS navigation and positioning signals. Once the GPS navigation and positioning signal is turned on, the drone entering the interfered area will lose the GPS navigation and positioning signal.

When using a gun-shaped drone jammer to participate in drone defense work, if the jamming frequency band that is turned on includes the flight control frequency band of the drone and the GPS navigation and positioning frequency band, the jammed drone will behave as : Out of control, unable to locate, unable to return automatically, no real-time image transmission signal, etc. This state is generally called "drone forced landing", and the drone will perform inertial flight or free landing or even fall directly in a disorderly manner to the ground. Another situation: If only the interference of the flight control frequency band of the drone is turned on, but the interference of the GPS navigation and positioning frequency band is not activated, most drones will quickly enter the automatic return mode. This state is generally referred to as "drone driving away".

Now we finally know the difference between the two working modes of "forced landing drone" and "driving away drone", so that we can choose the interference mode for the drone defense plan: when the drone needs to be captured or when it is destroyed, it is necessary to turn on the GPS navigation and positioning interference module. If the defense plan only requires that drones be inaccessible, there is no need to enable GPS navigation and positioning interference.
