PHARAO is to be launched by the European Space Agency (ESA) in 2013.<\/p>\n<p class=\"MsoNormal\">Atomic clocks are the most accurate timekeeping devices available to mankind yet they are susceptible to changes in gravitational pull, as predicted by Einstein\u2019s theory, as time itself is slewed by the Earth\u2019s pull. By placing this accurate atomic clock into orbit the effect of Earth\u2019s gravity is lessened allowing PHARAO to be more accurate than Earth based clock.<\/p>\n<p class=\"MsoNormal\">While <a href=\"https:\/\/www.galsys.co.uk\">atomic clocks<\/a> are not new to orbit, as many satellites; including the GPS network (Global Positioning System) contain atomic clocks, however, PHARAO will be among the most accurate clocks ever launched into space, allowing it to be used for far more detailed analysis.<\/p>\n<p class=\"MsoNormal\">Atomic clocks have been around since the 1960\u2019s but their increasing development has paved the way for more and more advanced technologies. Atomic clocks form the basis of many modern technologies from satellite navigation to allowing computer networks to communicate effectively across the globe.<\/p>\n<p class=\"MsoNormal\">Computer networks <a href=\"https:\/\/www.atomic-clock.galleon.eu.com\">receive time signals from atomic clocks<\/a> via <a href=\"https:\/\/www.galsys.co.uk\/time-server\/ntp-time-server.html\">NTP time servers<\/a> (Network Time Protocol) which can accurately synchronise a computer network to within a few milliseconds of UTC.<\/p>\n<p class=\"MsoNormal\">\n","protected":false},"excerpt":{"rendered":"<p>One of the world\u2019s most accurate atomic clocks is to be launched into orbit and attached to the International Space Station (ISS) thanks to an agreement signed by the French space agency.
