GPS Clock System For Time Synchronization

The synchronization of computers in an organization can be of paramount importance. Additionally, in many environments a large wall mounted display of accurate time is also required. A GPS clock system provides the ability to synchronize networks of computers and also provide accurate time to large digital and analog wall clocks.

The GPS system was introduced a number of years ago, primarily to provide global navigation and positioning. It is a satellite based system, maintained by the US Navy. GPS is a multi-satellite system, signals can be received in any location on the face of the Earth. In order to calculate accurate positioning information, the GPS system has to maintain a very accurate clock on each satellite. This clock can be used by timing equipment on Earth as a source of precise time. All that is required to obtain high precision timing signals is a relatively low-cost GPS antenna and receiver.

Network Timing and NTP

Network Time Protocol (NTP) is the standard means by which accurate time is disseminated around a network. A NTP server will typically receive time information from the GPS clock and distribute accurate time to network time clients. Typically, servers, workstations, network infrastructure and also clients such as telephone systems and CCTV systems can all access accurate time.

Accurate Time Displays

An accurate synchronized display of time is critical to the smooth running of many organisations. Ensuring that lessons or meetings start at the correct time or accurately logging events, an accurate synchronized time is importnant. Networked digital and analog wall clocks and time displays can access accurate time over an Ethernet network using NTP or SNTP to provide an accurate time display that can be traced back to GPS time.
