Because of the advancement in satellite navigation technologies and the increased coverage of the American GPS satellite network, many more administrators are choosing GPS as a source for a timing reference to synchronize their time servers too.<\/p>\n

Traditionally many more people opted to receive a timing source from either across the Internet or via specialist national time and frequency transmissions.\u00a0 However, the Global Positioning System is now by far the most popular method to receive a UTC time source from.<\/p>\n

UTC<\/a> (Coordinated Universal Time) is the global timescale based on the time told by atomic clocks which are the most accurate of time keeping devices.<\/p>\n

A GPS time server <\/a>is a relatively simple piece of hardware. Normally it consists of a dedicated NTP server with software, a GPS receiver and a GPS antenna. The antenna is the only drawback in using a dedicated GPS time server as it has to be positioned on the roof to have a clear view of the sky, although some dedicated GPS time servers can still keep time synchronized if they only receive a signal for a few hours a day, although this is not the most accurate way of time synchronization.<\/p>\n

Once connected, the GPS time server will receive the time signal from the GPS satellites and then distribute it to all devices that require synchronization.<\/p>\n

Most time servers, whether they receive a GPS signal or not, will use Network Time Protocol (NTP) to distribute the time signal to all devices.<\/p>\n

NTP is one of the Internet\u2019s oldest protocols and is by far the most widespread time synchronization protocols used. NTP is under constant development and can accurately synchronise a network to within a few milliseconds of UTC time via a dedicated GPS time server.<\/p>\n","protected":false},"excerpt":{"rendered":"
