• Installing a NTP GPS server Most dedicated NTP GPS servers are simple and easy to install, most manufacturers include guidance and full software with their devices to limited potential difficulties in installation. There are however, a few important aspects about installing a NTP GPS server that are often overlooked by some technicians. The GPS signal works by line-of-sight, that is to say that the satellite has to be visible to the antenna. Obviously as GPS satellites are-in orbit that means that the antenna has to have a good view of the sky. It is also important to keep the antenna away from sources of interference such as ...
  
  
• Common NTP Server Time Reference Problems The NTP server (Network Time Protocol) is one of the most used but least understood computer networking hardware items. A NTP Server is just a time server that uses the protocol NTP. Other time protocols do exist but NTP is by far the most widely used. The terms ‘NTP server’, ‘time server’ and ‘network time server’ are interchangeable and often the terms ‘radio clock’ or ‘GPS time server’ are used but these simply describe the method which the time servers receive a time reference. NTP servers receive a time source that they can then distribute amongst a network. NTP will check a ...
  
  
• Network Time Server – Common Troubleshooting Problems Dedicated network time servers are on the whole reliable pieces of hardware and very rarely do they fail to receive and distribute a timing signal.  However, some common errors do occur: Network time servers that receive a time signal from the GPS satellite system can often fail to find a signal if they have not been given enough time to lock on to a satellite. All GPS network time servers should be left on for at least 48 hours to ensure the time server can get a stable lock on a the satellites. Network time servers that receive a radio signal can ...
  
  
• GPS Time Server Troubleshooting Tips A GPS time server is probably the most secure, accurate and reliable method of receiving a UTC time signal (Coordinated Universal Time). However, some problems do occur but fortunately the solutions are relatively straightforward. One of the most common causes for problems with a GPS time server is in failure to receive a signal. While the GPS transmission is extremely impervious to weather interference and as most GPS time servers can receive a signal from between one and twelve different satellites, the transmission is very robust. If a signal is not being received then the first point of call is the ...
  
  
• 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 ...
