Description：

1.The NTP network time server is a time server based on NTP (v2, v3, v4)/SNTP protocol.

2.Obtain standard UTC time information from GNSS satellite receivers and transmit this information over the network.

3.Devices that require time signals, such as computers, controllers, etc., can be synchronized with standard clock signals.

4.Now the network timing function. Standard clock information is transmitted over a TCP/IP network, supporting point-to-point and broadcast transmission

5.Loss mode.

6.The product is easy to use, just plug in the GNSS satellite antenna and the entire network can be time synchronized.

7.Small size, easy to install, ultra low power consumption, plug and play
