Industry leading technology, flexible configuration, simple and easy to use, small portable GNSS full frequency navigation interference signal simulation source, suitable for multiple application scenarios such as handheld, backpack, and fixed deployment.
NIF4000 is a portable navigation suppression and deception interference signal generation device that adopts a more powerful computing platform and a reconfigurable and configurable architecture design. It can flexibly configure the simultaneous output of navigation deception and deception interference signals, and supports GNSS full frequency navigation suppression and deception interference simulation. Has rich interference style generation capabilities, supporting single tone, sweep frequency, amplitude modulation, frequency modulation, pulse, white noise, digital modulation, and flicker interference; It also supports generative deception jamming simulation, with a built-in highly stable clock module, which can be fully synchronized with the actual Satellite navigation to achieve seamless deception. It can also import deception tracks in real time to complete the deception of highly dynamic targets.
The device has the characteristics of portability, miniaturization, simplicity, and ease of use. The overall weight (including battery) does not exceed 5kg, making it suitable for flexible and mobile navigation signal interference applications carried by hand or on the back.
