Network Time Synchronisation using GPS
Posted on May 20, 2008 - Filed Under 336 | Leave a Comment
This article describes the components required to utilise GPS for computer timing applications. It also discusses how the GPS system can be used for computer network timing by using the Network Time Protocol (NTP) and NTP time servers.
Nowadays GPS is most commonly known for vehicle navigation solutions. However, the GPS system can be used for many other useful purposes. For instance, many computer network time synchronisation solutions, such as NTP time servers, use the atomic clocks on board each GPS satellite for accurate timing. The GPS system can be used as an accurate reference clock for synchronising time-critical applications on computers and networks. This article describes how computer systems can utilise GPS time and discusses what equipment is required to provide a precision timing reference.
