The SHTS2000 Satellite Synchronization Device is a time synchronization system specially designed for the power industry. Capable of receiving GPS and Beidou radio signals, the system adopts the advanced “Time Tame algorithm” in achieving a perfect combination of the long steady state of the satellite time and that of the crystal oscillator time. It provides high-precision and high-reliability time signals for various automation devices at power plants and transformer substations fully in compliance with the requirements in Part I: Technical Specifications, DLT 1100.1-2009 Power System Time Synchronization System.

? With the built-in atomic clock or high constant temperature OCXO available to be selected by the customer, the device adopts the advanced tame algorithm, resulting in high-? precision signals and a precision in timekeeping of up to 1us/h.
? It can come with a master/slave configuration, where every master clock simultaneously receives GPS, Beidou, and 1 channel of mutual-backup reference source and adopts the ? multi-source selection and judgment mechanism to ensure system stability and reliability.
? Compensated transmission delay can be set so that time mark transmission will not be limited by distance and medium.
? Supporting the output of multiple time mark signals such as 1PPS/1PPM/1PPH, IRIG-B, serial message, NTP, and PTP.
? Supporting multiple electrical types such as idle contact, differential, 24V active, and TTL.
? A modular design is adopted so that types of output signals can be flexibly configured.
? It has power remote or local monitoring software to facilitate management and monitoring operations and achieve network-based management.

The system is applicable at substations and power plants of various levels and provides various types of high-precision and high-reliability time service signals.
