T7905 SNTP time server supports NTP and SNTP network synchronization protocols, and is a high-precision, high-capacity, high-security clock product. The hardware of the device adopts redundant architecture design, and the high-precision clock comes directly from the atomic clocks of each satellite in the GNSS system, and tames the local clock source through signal analysis to realize the function of keeping the local clock accurately after the loss of satellite signals. The software of the device adopts a variety of anti-jamming detection and identification algorithms of BDSTAR TIME to detect signal anomalies caused by interference and malicious attacks on satellite signals. Unique embedded hardware design, high-efficiency Linux operating system, flexible expansion of a variety of clock signal output.
