Now many secret units or key government departments have begun to install and use drone jamming equipment. In some large-scale event sites or places where people gather together, from the perspective of public security and stability, secret service personnel will also be equipped with portable drone jamming devices , such as hand-held drone jamming guns, etc. And once a malicious drone is found, the expulsion and forced landing modes will be mentioned in how to deal with it. Then, what exactly does the expulsion and forced landing in the drone jamming equipment represent? How much difference is there between the two?

To drive away, as the name suggests, means to drive away, forcibly drive away. If the drone is flying close to its own side, and the side only wants to let it fly away from the scene as soon as possible, or let it return to home automatically, so as not to harass its own side, then it is to activate the drive away mode of the drone interference device. The drive away mode usually does not start the interference of the GPS positioning frequency band of the drone, so most of the drone models or varieties, in the drive away mode, firstly lose the functions of image transmission and flight control. Then the drone will turn on the automatic return mode to return to the initial position of the drone.

Forced landing refers to the need to take measures such as capturing, grasping or damaging the drone. When the drone jamming device operates in the forced landing mode, it will interfere with the communication frequency bands such as the drone's image transmission, flight control, and navigation and positioning at the same time. and suppression, the drone in this state not only cannot receive the flight control instructions of the remote controller operator, but also cannot receive images and GPS positioning information. Moreover, the drone cannot start the automatic return-to-home mode on its own due to the loss of location information. Under the continuous action of drone jamming equipment, most UAVs will take actions such as landing or hovering in place, and a small number of UAVs will fall in place.

Through the above description, it can be compared to the expulsion and forced landing functions in the drone jamming equipment. The most obvious difference is whether the interference is aimed at GSP navigation and positioning.
