The time synchronization board is an electronic board used to achieve time synchronization between devices or systems.

The following is a detailed introduction for you:

Satellite timing synchronization:

Built-in satellite receiving modules, such as GPS and Beidou modules, receive precise time signals transmitted by satellites. Satellite signals contain accurate time information. The board obtains the standard time reference by parsing the signal to synchronize its own time with the satellite time. It is widely used in scenarios with open sky views and high-precision time synchronization.

Network Protocol Synchronization:

Supports network time synchronization protocols such as IEEE 1588 and transmits time information through the network. In the network system, the master clock device sends time synchronization messages to the slave clock device according to the protocol. The slave clock device receives and processes the messages, adjusts the local time, and achieves time synchronization with the master clock. It is suitable for distributed network systems.

Internal clock source calibration:

Equipped with high-precision oscillators, such as oven-controlled crystal oscillators (OCXOs), rubidium atomic clocks, etc., to generate stable clock signals. At the same time, the internal clock source is calibrated and tamed according to the external time reference signal to ensure the accuracy and stability of the internal clock. When the external time reference is abnormal, the internal clock source can maintain high-precision time output within a certain period of time.
