GPS berieme ako samozrejmos\u0165. Pou\u017e\u00edvame ho v mobile, aute, hodink\u00e1ch, lietadl\u00e1ch aj v kritickej infra\u0161trukt\u00fare. Len\u017ee pr\u00e1ve preto je d\u00f4le\u017eit\u00e9, kto tak\u00fdto syst\u00e9m ovl\u00e1da. Eur\u00f3pa si to uvedomila u\u017e d\u00e1vno a dnes u\u017e m\u00e1 vlastn\u00fa odpove\u010f.<\/p>\n
Vol\u00e1 sa Galileo a nejde iba o z\u00e1lo\u017en\u00fa navig\u00e1ciu k americk\u00e9mu GPS. Eur\u00f3pska vesm\u00edrna agent\u00fara ESA ho ozna\u010duje za najpresnej\u0161\u00ed glob\u00e1lny satelitn\u00fd naviga\u010dn\u00fd syst\u00e9m na svete. Funguje od roku 2016 a pod\u013ea ESA ho dnes vyu\u017e\u00edva viac ne\u017e p\u00e4\u0165 mili\u00e1rd pou\u017e\u00edvate\u013eov smartf\u00f3nov po celom svete.<\/p>\n
V\u0161etky smartf\u00f3ny pred\u00e1van\u00e9 na jednotnom eur\u00f3pskom trhu u\u017e Galileo musia podporova\u0165. Be\u017en\u00fd pou\u017e\u00edvate\u013e si to \u010dasto ani nev\u0161imne, preto\u017ee telef\u00f3n kombinuje viacero syst\u00e9mov naraz. Okrem GPS tak m\u00f4\u017ee vyu\u017e\u00edva\u0165 aj Galileo, pr\u00edpadne \u010fal\u0161ie glob\u00e1lne naviga\u010dn\u00e9 siete.<\/p>\n
Eur\u00f3pa preber\u00e1 kontrolu<\/p>\n
Americk\u00e9 GPS je civilne dostupn\u00e9 po celom svete, no jeho p\u00f4vod aj spr\u00e1va s\u00fa vojensk\u00e9. Pre Eur\u00f3pu to znamen\u00e1 strategick\u00fa z\u00e1vislos\u0165 od syst\u00e9mu, ktor\u00fd neovl\u00e1da. Galileo vzniklo pr\u00e1ve preto, aby mala Eur\u00f3pska \u00fania vlastn\u00fa satelitn\u00fa navig\u00e1ciu, vlastn\u00fd \u010dasov\u00fd sign\u00e1l a v\u00e4\u010d\u0161iu nez\u00e1vislos\u0165 pri slu\u017eb\u00e1ch, na ktor\u00fdch stoj\u00ed doprava, energetika, telekomunik\u00e1cie aj z\u00e1chrann\u00e9 zlo\u017eky.<\/p>\n
Ve\u013ek\u00fd symbolick\u00fd krok pri\u0161iel 17. decembra 2025, ke\u010f raketa Ariane 6 vyniesla na obe\u017en\u00fa dr\u00e1hu dve \u010fal\u0161ie dru\u017eice Galileo. I\u0161lo o prv\u00fd \u0161tart dru\u017e\u00edc Galileo na Ariane 6 a ESA ho ozna\u010dila za posilnenie eur\u00f3pskej odolnosti a auton\u00f3mie. Po zaraden\u00ed t\u00fdchto dru\u017e\u00edc m\u00e1 ma\u0165 kon\u0161tel\u00e1cia 29 akt\u00edvnych satelitov.<\/p>\n
Nie je to detail. Eur\u00f3pa t\u00fdm posil\u0148uje cel\u00fd re\u0165azec od v\u00fdroby dru\u017e\u00edc cez ich vynesenie a\u017e po prev\u00e1dzku naviga\u010dnej slu\u017eby. V \u010dase, ke\u010f sa \u010doraz \u010dastej\u0161ie hovor\u00ed o ru\u0161en\u00ed a fal\u0161ovan\u00ed GPS sign\u00e1lu, m\u00e1 vlastn\u00fd syst\u00e9m ove\u013ea v\u00e4\u010d\u0161iu hodnotu ne\u017e len pohodlnej\u0161iu navig\u00e1ciu do pr\u00e1ce.<\/p>\n
Celeste prid\u00e1 n\u00edzku obe\u017en\u00fa dr\u00e1hu<\/p>\n
\u010eal\u0161\u00edm krokom je projekt Celeste. ESA 28. marca 2026 vypustila z Nov\u00e9ho Z\u00e9landu prv\u00e9 dve dru\u017eice tejto demon\u0161tra\u010dnej misie. Celeste m\u00e1 testova\u0165, ako m\u00f4\u017ee n\u00edzkoorbit\u00e1lna naviga\u010dn\u00e1 vrstva doplni\u0165 Galileo, ktor\u00e9 funguje na strednej obe\u017enej dr\u00e1he vo v\u00fd\u0161ke pribli\u017ene 23-tis\u00edc kilometrov.<\/p>\n
Dru\u017eice bli\u017e\u0161ie k Zemi m\u00f4\u017eu pon\u00faknu\u0165 robustnej\u0161\u00ed sign\u00e1l, nov\u00e9 frekvencie a lep\u0161iu dostupnos\u0165 v prostred\u00ed, kde m\u00e1 klasick\u00e1 satelitn\u00e1 navig\u00e1cia probl\u00e9my. <\/p>\n

Galileo v\u0161ak prinieslo aj slu\u017ebu High Accuracy Service, ktor\u00e1 je dostupn\u00e1 bezplatne a pri vhodnom prij\u00edma\u010di dok\u00e1\u017ee v\u00fdrazne zlep\u0161i\u0165 polohu.
