Main Applications:
Suitable for industries such as power, carriers, rail transit, and security.
Product Overview
The GNR300 satellite space-time isolation device is a satellite signal security isolation product developed to address the vulnerability of Beidou/GPS civilian signals to interference, attacks, and spoofing, which can lead to inability to maintain proper timing and positioning.
Features:
2 satellite inputs, 2 satellite outputs (expandable)
Protects internal components against long-term feeder short-circuit conditions
Protects against forwarding, generation, and intrusion signal spoofing
Provides warnings via indicators and standard data when satellites are unavailable (e.g., due to national regional protection, GPS service shutdown, etc.) or when quality degrades (e.g., due to interference).
Secure signal output is unaffected by GPS spoofing signals, including generation and forwarding.
Main Applications:
Suitable for industries such as power, carriers, rail transit, and security.
