Working principle of the DJ-04-70 jammer :
By pointing the device in the direction of the UAV's approach, the DJ-04-70 effectively blocks control signals, video transmission, and satellite positioning of the UAV. This prevents the UAV from returning, transmitting information, or performing any planned actions. Instead, the drone usually reacts in one of the following predictable scenarios:
- Emergency landing (in most cases), which allows you to return the UAV.
- Hovering until the battery is completely discharged, which leads to a subsequent landing.
- Hovering with subsequent drifting downwind, which can potentially lead to a crash if the UAV gets tangled in foliage.
- Uncontrolled fall (programmable in some UAV models).
Application:
DJ-04-70 is well suited for a wide range of scenarios, including territorial defense, checkpoints, roadblocks, government compounds, military bases, anti-terrorism units, anti-drug units, border control units, private property protection, countering commercial espionage, combating arms smuggling, addressing drug-related issues in correctional facilities, and more.
