Fanshine ChronoShield Series
The ChronoShield Series is designed to protect and stabilize GNSS-based timing systems against interference and spoofing threats.

GNSS Signal Protection Unit
S1000
Provides secure isolation and protection for GNSS signals by detecting abnormal inputs and preventing spoofed or interfered signals from entering the system.

High-Precision Time Synchronization Unit
SHC1000
Delivers high-precision timing signals with stable synchronization performance, supporting NTP/PTP protocols for critical infrastructure systems.
Solutions Overview
The solution combines signal protection and high-precision timing to ensure secure and reliable synchronization.
GNSS timing signals are critical for power grids, telecom networks, and financial systems. Our timing protection solutions ensure stable and reliable synchronization by detecting and mitigating interference and spoofing threats.
Can be integrated with anti-drone systems to ensure full-spectrum signal security.
How It Works
Timing protection systems ensure the reliability of GNSS-based synchronization by monitoring signal integrity and identifying anomalies caused by interference or spoofing.
When abnormal signals are detected, the system maintains stable timing through local reference or holdover mechanisms, preventing disruption to critical infrastructure operations.
