Vsaka oseba, avtomobil, ladja ali letalo, opremljeno s satelitskim navigacijskim sistemom, lahko natan\u010dno dolo\u010di svoj polo\u017eaj z natan\u010dnostjo 15 do 20 metrov.<\/p>\n<p>Satelitska navigacija temelji na uporabi sprejemnika, ki izra\u010duna svoj polo\u017eaj s pomo\u010djo signalov, ki jih po\u0161iljajo vsaj \u0161tirje sateliti.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"389\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2001\/11\/GPS2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2001\/11\/gps2\/17865564-3-eng-GB\/GPS.jpg\" alt=\"GPS\"><figcaption>GPS<\/figcaption><\/figure>\n<p>Sistem, ki ga danes uporabljamo v vsakdanjem \u017eivljenju, je bil prvotno razvit za voja\u0161ke namene. Med letoma 1960 in 1968 je ameri\u0161ka vojska v orbito izstrelila 23 navigacijskih satelitov, ki so pomagali pri navigaciji podmornic razreda Polaris.<\/p>\n<p>Iz teh sistemov se je s\u010dasoma razvil globalni sistem za dolo\u010danje polo\u017eaja (GPS). Podobni sistem, imenovan Glonass, je uvedla ruska vojska. Oba sistema sta zdaj na voljo tako za civilno kot za voja\u0161ko rabo. Zato si je Evropa \u017eelela imeti svoj lasten, zanesljiv sistem.<\/p>\n<p>Evropa je zdaj uvedla sistem z imenom EGNOS, ki izbolj\u0161uje natan\u010dnost sistema GPS. ESA in Evropska skupnost skupaj razvijata tudi lasten evropski civilni (nevoja\u0161ki) navigacijski sistem. Ta sistem, imenovan Galileo, bo prvi popolnoma civilni sistem za globalno navigacijo.<\/p>","protected":false},"excerpt":{"rendered":"<p>Long ago, people who sailed the sea found their way by studying the positions of the Sun, Moon and stars.
