Product Overview:
The satellite signal security isolation device is a satellite time and space security protection product developed to address the vulnerability of satellite signals to interference, attacks, and spoofing, which can affect normal satellite signal reception and lead to abnormal operation of satellite time synchronization devices. The product real-time detects spoofing and interference signals and shuts off the satellite signal output in the presence of interference or spoofing. The satellite signal security isolation device is suitable for industries such as power, transportation, intelligent manufacturing, medical, and finance, and can strengthen the anti-interference and anti-spoofing capabilities of satellite time synchronization devices.
Features:
(1) The device features a 19-inch 1U rack-mount design;
(2) Supports detection and alarm output for forwarding and generated spoofing and interference signals;
(3) Supports protection against forwarding, generated, and intrusive signal spoofing;
(4) Possesses the function of shutting off satellite signals under spoofing and interference conditions;
(5) Provides two-way satellite signal input and output functions;
(6) Supports remote WEB monitoring of device status and setting of operating parameters;
(7) Tested and verified by the State Grid Electric Power Research Institute Experiment and Verification Center;
