- Commodity name: Generative DNSIS-612B
The satellite spatiotemporal security isolation device is a satellite‑based spatiotemporal security protection product developed to address the vulnerabilities of satellite signals—such as susceptibility to interference, attacks, and spoofing—which can disrupt the reception of normal satellite signals and cause satellite time‑synchronization equipment to malfunction.

Product Features
The chassis adopts a 19-inch 1U rack-mount design.
Supports转发式 and generative deception, as well as signal detection and alarm output for interference.
Supports defense against replay, generation, and intrusion-based signal deception.
Time-Synchronization Security Protection Isolation Device DNSIS-612B
It is capable of disabling satellite signals under conditions of deception and interference.
It features dual-channel satellite signal input and output capabilities.
Supports remote web-based monitoring of device operating status and configuration of operating parameters.
Product Overview

The satellite spatiotemporal security isolation device is a satellite‑based spatiotemporal protection solution developed to address the vulnerabilities of satellite signals—such as susceptibility to interference, attacks, and spoofing—that can disrupt normal signal reception and cause satellite time‑synchronization equipment to malfunction. The device continuously detects spoofing and jamming signals, ensuring that, even in denied‑access maintenance mode, the position and timing accuracy of the output navigation satellite signals remain stable. This satellite spatiotemporal security isolation device is suitable for enhancing the anti‑interference and anti‑spoofing capabilities of satellite time‑synchronization systems across industries including power, transportation, smart manufacturing, healthcare, and finance.

Installation method

The satellite signal security isolation device is easy to install—simply connect it between the existing antenna and the satellite timing equipment. Attach the original satellite antenna to the device, and then connect the device’s output port to the timing equipment’s antenna interface.

Technical Specifications
