NTP Configuration

NTP, or Network Time Protocol, is a protocol designed to synchronize the clocks of computers over a network. The use of an external NTP time server allows the NetRS to set its own internal clock when GPS is not available, such as when the receiver powers up. This can be helpful if the receiver has been off for more than a day or two, and in some situations it can help to reduce the amount of time required to acquire satellites and begin logging or streaming sessions. Once the receiver begins tracking GPS satellites, however, the GPS time solution is used as the time source. The GPS time solution is always the primary time source when it is available.

To use one or more external NTP time servers, specify the address of up to three NTP time servers in the External Time Servers fields. The address can be specified using a name, such as: gpstime.trimble.com

Or by using an IP address, such as: 206.40.88.30

The Disable using NTP servers checkbox should be unchecked for normal operation. When it is checked, no attempt will be made to use an NTP server to synchronize the internal clock, and accurate time will not be established until the receiver starts tracking GPS satellites.
