- Commodity name: Generative DNSIS-612A
DNSIS-612A employs advanced anti-spoofing and anti‑jamming technologies, enabling it to effectively detect and identify spoofing and jamming signals, and swiftly shut down or switch over to normal operation in response to abnormal signals, thereby mitigating the effects of spoofing and jamming.

Product Features
A fully autonomous baseband, equipped with multi-constellation, multi-frequency satellite spoofing and jamming signal detection and identification capabilities, supporting single‑Beidou full‑frequency anti‑spoofing and enhanced signal generation.
It features synchronous hold and reject‑maintain operating modes.
► Synchronization and Maintenance: Receives authentic satellite signals and synchronizes with them to deliver high-precision timing outputs;
► Holdover: When satellite signals are unavailable, the device can still generate a high‑precision timing signal to maintain timekeeping.
It features two operating modes—signal shutdown mode and reinforced output generation mode—allowing users to choose flexibly.
► In shutdown mode, deceptive jamming signals can be effectively filtered, isolating anomalous signals.
► In the hardened output mode, it can provide high‑security, high‑trust time‑keeping output with timing accuracy no worse than that of real satellite signals, unaffected by spoofing signals.
Powerful security features
► High-sensitivity deception‑jamming detection and multi‑deception‑jamming signal processing;
► Fully autonomous baseband, with multi‑modal integrated deception and jamming detection;
► Anti‑forwarding, generative, and invasive deception jamming;
► Deception detection and rapid response capabilities for alert elimination;
► Excellent anti-interference performance
High‑safety design: when the device loses power or malfunctions, the RF switch closes, allowing satellite signals to pass through normally without affecting the operation of downstream equipment.
Plug-and-play, in-situ reinforcement, no need to replace the timing equipment, user-friendly, with a simple web‑based interface.
High reliability, with flexible switching between shutdown mode and hardened output generation mode, and proprietary smoothing technology that ensures timing stability during state transitions.
Product Overview

The DNSIS-612A employs advanced anti-spoofing and anti‑jamming technologies, enabling it to effectively detect and identify spoofing and jamming signals, swiftly shut down or switch off anomalous signals, and mitigate the effects of such interference. By integrating a satellite signal generation module, the DNSIS-612A offers satellite navigation signal simulation capabilities, allowing it to autonomously generate simulated signals to maintain timing output and provide reliable, uninterrupted time‑keeping for downstream timing equipment. Furthermore, through in‑situ hardening, the DNSIS-612A helps users strengthen timing security, making it widely applicable for security reinforcement across various high‑precision timing industries.
