Majd 1300 k\u00f6r\u00fcl az ir\u00e1nyt\u0171 megjelen\u00e9se kiss\u00e9 megk\u00f6nny\u00edtette ezeknek a haj\u00f3soknak az \u00e9let\u00e9t.<\/p>\n<\/div>\n

Manaps\u00e1g az \u0171rtechnol\u00f3gia r\u00e9v\u00e9n m\u00e1r senki sem t\u00e9vedhet el.

A rendszer, amelyet ma a mindennapi \u00e9letben haszn\u00e1lunk, eredetileg katonai c\u00e9lokra ker\u00fclt kifejleszt\u00e9sre. 1960 \u00e9s 1968 k\u00f6z\u00f6tt az amerikai hadsereg 23 navig\u00e1ci\u00f3s m\u0171holdat \u00e1ll\u00edtott p\u00e1ly\u00e1ra a Polaris tengeralattj\u00e1r\u00f3k navig\u00e1ci\u00f3j\u00e1nak t\u00e1mogat\u00e1s\u00e1ra.<\/p>\n

Ezekb\u0151l v\u00e9g\u00fcl a Glob\u00e1lis Helymeghat\u00e1roz\u00f3 Rendszer (GPS) alakult ki. Oroszorsz\u00e1gban a hadsereg egy hasonl\u00f3 rendszert, a Glonass-t vezette be.

Eur\u00f3pa most bevezette az EGNOS nev\u0171 rendszert, amely jav\u00edtja a GPS-rendszer pontoss\u00e1g\u00e1t. Az ESA \u00e9s az Eur\u00f3pai K\u00f6z\u00f6ss\u00e9g emellett k\u00f6z\u00f6sen fejlesztik Eur\u00f3pa saj\u00e1t polg\u00e1ri (nem katonai) navig\u00e1ci\u00f3s rendszer\u00e9t. A Galileo n\u00e9vre keresztelt rendszer lesz az els\u0151 teljesen polg\u00e1ri c\u00e9l\u00fa glob\u00e1lis navig\u00e1ci\u00f3s rendszer.<\/p>","protected":false},"excerpt":{"rendered":"
