NTP Configuration
Use these settings to configure the NTP (Network Time Protocol) Client settings for the receiver. NTP is an internet protocol used to synchronize computer clock time sources in a network.
Select Network Configuration / NTP.
Client
External Time Servers – Enter the IP address or DNS address and port of the NTP server that the receiver will connect to. This allows the receiver to synchronize the internal receiver clock to an Internet time source, which can improve satellite acquisition if the receiver was powered off for a long period of time. The receiver is preconfigured with three default time servers.
Enable NTP client – Select this check box if you require the receiver to be an NTP client. Use this feature to synchronize the receiver time using an external time source.
Server
Enable NTP server – Select this check box if you require the receiver to be an NTP server. Use this feature to synchronize devices on a network, for example, other computers. This is useful on an offshore installation when an external NTP time server is not available and other devices on the network cannot access the 1PPS, but they are on a local network (wired or wireless) and require time synchronization.
Reference clock offset – If an accurate absolute time service is required, then the delay caused by the length of the antenna cable needs to be determined and entered as nanoseconds delay.
