The Beidou spatiotemporal security isolation device, which is safe, controllable, stable, and continuous, helps users establish a complete, reliable, and anti attack spatiotemporal defense system.
The NPS4000 adopts navigation digital signal fast demodulation, solution processing technology, and high-precision positioning, navigation, and time service signal simulation technology, which can automatically identify deceptive interference signals in the free space environment, provide timely warnings, remind users, and quickly switch navigation signals or eliminate interference signals to avoid interference to the backend GNSS navigation time service terminal, resulting in deviation or error in the output reference clock information. The NPS4000 can be connected in series between the original antenna and timing equipment, without the need to change the original timing equipment and antenna system.
NPS4000 can help users build a secure and powerful defense system, enabling them to better monitor, respond, defend, and eliminate threats, ensuring the normal operation of the system timing network.
