T-ASJ20 GNSS Timing Safety Isolation Device

The T-ASJ20 GNSS timing security isolation device is designed for scenarios such as GPS signal failure, interference, or spoofing. By utilizing a local Beidou timebase, simulated signals, and system isolation protection, it provides a secure time base for industries such as communications and power. The device supports protection against forwarding, generation, and intrusive interference, and features built-in local clock training and timebase holdover, ensuring better than 100ns timing accuracy even in the presence of external signal anomalies. It automatically switches to Beidou timing, offering seamless switching and real-time monitoring and alarming capabilities. Interference onset and removal times are less than 15s and 180s, respectively, and it can be remotely configured and upgraded online.

Applicable fields: power transmission, power generation, substation, finance and securities, communications, transportation, national defense, etc.
