• GPS Time Server – NAVSTAR NAVSTAR GPS is not an acronym although many people assume it is. NAVSTAR is the original name given to the US military’s Global Navigational Satellite System (GNSS). Currently NAVSTAR is the world’s only fully functioning GNSS, although the European Galileo system is expected to be operational in a few years and the former Russian GLONASS system is being put back into commission after it fell into disrepair following the collapse of the Soviet Union. NAVSTAR is controlled and run by the US Air Force’s 50th Space Wing but has been available for civilian use since the late 1980’s when a Korean passenger ...
  
  
• NTP GPS Server for Time Critical Applications The GPS (Global Positioning System) is a Global Navigational Satellite System (GNSS) controlled and run by the United States of America. GNSS systems work by using satellites several thousand miles above the Earth’s surface that beam timing information down to a GNSS receiver (like the satellite navigation unit in our cars). It is this information that is used by the GPS receiver to triangulate an exact position. They can only do this by having onboard their own highly accurate atomic clock as the distance the satellites are away from the Earth, even an inaccuracy of a second or two could mean ...
  
  
• GPS Time Server – GPS Facts From military hardware to GPS time servers The Global Positioning System was designed and built by the US military in the late 1970’s, although it didn’t achieve initial operational capability until 1993. GPS was originally designed as a military only system but in 1983 after a USSR aircraft shot down a Korean airliner that had accidentally strayed into Soviet airspace, the then President of the United States, Ronald Reagan, vowed the system would be available for civilian use once completed. Full Operational Capability was declared by the now named NAVSTAR GPS in April 1995 and in 1996 to fulfil his predecessors ...

• GPS Time Server – Utilising Satellite Navigation as a Timing Source Satellite navigation has been around for the last few decades courtesy of the American military controlled GPS system (Global Positioning System). The GPS network is currently the World’s only GNSS (global navigation satellite system, although Europe, Russia and China are developing their own. GNSS systems like GPS are based on the same principle. A constellation of satellites orbiting the Earth each have onboard an atomic clock. These clocks are accurate to within a few microseconds and it is this time-telling accuracy that allows satellite navigation possible. The GPS satellite continually transmits its location along with the time told by its atomic clock. ...
