However, even then the effect would be a degradation of performance, rather than complete failure to operate.<\/p>\n<p>\u201cA GPS timing receiver is unlikely to be affected significantly since, once it has determined its position when turned on, every satellite it observes provides it with useful timing information. A small reduction in the number of satellites in view should not degrade its performance much.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Following recent media reports on the lack of investment in the USA\u2019s Global Navigation Satellite System &#8211; GPS (Global Positioning System) and the potential failure of navigational receivers in recent years, time synchronisation specialists, Galleon Systems, would like to ensure all their customers that any failure of the GPS network will not affect current GPS&hellip;<\/p>\n<p><a class=\"btn btn-primary\" href=\"https:\/\/www.galsys.co.uk\/news\/reported-gps-fears-should-not-affect-time-synchonisation\/\">Continue reading <i class=\"fas fa-arrow-right\"><\/i><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3,6,62,12,13],"tags":[19,20,27,28,29],"class_list":["post-573","post","type-post","status-publish","format-standard","hentry","category-advanced-ntp","category-gps","category-network-security","category-time-server","category-time-synchronisation","tag-gps-ntp-server","tag-gps-ntp-time-server","tag-ntp-gps-server","tag-ntp-gps-time-server","tag-ntp-servers"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
