• Understanding a NTP GPS Server A NTP GPS Server is a type of time server that uses Network Time Protocol (NTP) as a method for synchronizing the time on network devices and computers after receiving a time signal from he GPS network. The GPS (Global Positioning System) network is a constellation of satellites owned and operated by the USA military. Most people are aware of GPS as an aid for satellite navigation. In actual fact, the basis of the transmissions broadcast by the GPS satellites is a time signal. This time signal is generated by the satellite’s onboard atomic clock. It is this information that a ...
  
  
• NTP Time Server – Installation advice Installation of a NTP time server (network time protocol) is relatively straight forward. Like other computer servers a NTP time server can be mounted to a rack or left as a stand alone. NTP time servers are the same as other servers in their installation except that there is one other consideration to take into account and that is where the time signal is coming from. NTP time servers can utilise any timing signal but for the purposes of network time synchronisation a UTC (Coordinated Universal Time) time source is a prerequisite. UTC is available from several sources. The most common source ...
  
  
• Utilising UTC To receive and distribute and authenticated UTC time source there are currently two types of NTP server, the GPS NTP server and the radio referenced NTP server. While both these systems distribute UTC in identical ways the way they receive the timing information differs. A GPS NTP time server is an ideal time and frequency source because it can provide highly accurate time anywhere in the world using relatively cheap components.  Each GPS satellite transmits in two frequencies L2 for the military use and L1 for use by civilians transmitted at 1575 MHz, Low-cost GPS antennas and receivers are now widely ...
  
  
• Synchronisation and Time Server Basics A time server is a computer device that obtains a timing reference from a  particular source and transfers it to a network and its clients. A time server does not rely on a system clock for timing information (all though they can be set to) as the internal clocks in PCs are prone to drift. Instead a time server will request timing information from an authoritative source and synchronises to it. Most time servers use NTP (network Time Protocol) to synchronise devices and networks using the information gathered by the time server. Most network administrators prefer to get their timing reference from a ...
  
  
• NTP Server and Digital Wall Clocks Many network administrators are aware of the NTP server (Network Time Protocol) and how it synchronises a computer network to UTC time (Coordinated Universal Time). These devices have revolutionised the way we work and trade in the global marketplace ensuring that computer networks from across the world are synchronised to the same time. But computer networks are not the only part of an organisation that requires to know the time, people too are constantly relying on the time and if a computer network is running reliable and accurate time then it makes sense that the workforce is too. However, in many organisations ...
