The SG-1 is a defensive timing protection device designed to safeguard GPS/BDS-based timing systems in power grids, telecom networks, and data centers against spoofing and jamming attacks. Installed inline between existing timing receivers and antennas — requiring no replacement of existing equipment — it monitors GNSS signal integrity in real time, automatically isolates anomalous signals, and maintains uninterrupted timing output even under full-spectrum denial conditions. Maintains ≥1 hour of accurate timing (≤500ns) after complete satellite signal loss.

Alarm Detection Time: ≤15 s

Alarm Clear Time: ≤120 s

Supported GNSS: GPS L1 / BDS B1I / BDS B3I
