EPRTC-1 Enhanced Primary Reference Time Clock
EPRTC-1 is currently the first Enhanced Primary Reference Time Clock in the industry capable of independent operation. When tracking GNSS, its deviation relative to UTC is better than 30ns, and its timing accuracy meets the ITU-T G.8272.1 standard while hold state.
EPRTC-1 Enhanced Primary Reference Time Clock can provide all timing services required by various industries.
A powerful industrial-grade processor can meet the needs for large-capacity timing services. The device supports BeiDou, GPS, GLONASS, Galileo modes, and hybrid modes. Due to its ultra-high time-frequency performance, it can also be used to monitor regional GNSS performance.For user convenience in managing the device, it supports multiple management methods including SSH remote login management, local serial port management, and remote SNMP management.
