Europa a\u0219teapt\u0103 cu \u00eencredere s\u0103 dispun\u0103 de primul sistem de naviga\u021bie prin satelit din lume cu destina\u021bie non-militar\u0103, acum c\u0103 primii patru sateli\u021bi Galileo au trecut testele cu brio.<\/p>\n<\/div>\n

Cvartetul Galileo a fost lansat \u00een 2011 \u0219i 2012 pentru a demonstra c\u0103 acest sistem complex func\u021biona a\u0219a cum se anun\u021base. Motivul pentru care au lansat patru sateli\u021bi este c\u0103 acesta reprezint\u0103 num\u0103rul minim de sateli\u021bi necesar pentru localizarea precis\u0103 a locurilor de pe P\u0103m\u00e2nt. De atunci, ace\u0219tia au trecut printr-o perioad\u0103 de teste pentru a demonstra c\u0103 sistemul func\u021bioneaz\u0103 conform planului.<\/p>\n

La 12 martie 2013, sateli\u021bii au realizat prima lor localizare istoric\u0103 precis\u0103 a unui punct de pe suprafa\u021ba P\u0103m\u00e2ntului. \u00cen lunile urm\u0103toare, au fost transmise numeroase mesaje de naviga\u021bie \u00een cadrul unei verific\u0103ri intensive a \u00eentregului sistem Galileo.<\/p>\n

Toat\u0103 aceast\u0103 munc\u0103 asidu\u0103 a demonstrat c\u0103 sistemul Galileo func\u021bioneaz\u0103 foarte bine. Cu doar patru sateli\u021bi, sistemul a reu\u0219it s\u0103 determine pozi\u021biile cu o precizie de 8 m pe orizontal\u0103 \u0219i 9 m pe vertical\u0103. Precizia medie de cronometrare este de 10 miliarde de secunde, iar majoritatea semnalelor de urgen\u021b\u0103 au fost localizate rapid cu o precizie de 2 km. Aceste performan\u021be vor fi \u0219i mai bune odat\u0103 cu punerea \u00een func\u021biune a sistemului Galileo complet.<\/p>\n

Europa a\u0219teapt\u0103 cu ner\u0103bdare lansarea sateli\u021bilor r\u0103ma\u0219i \u0219i instalarea unor sta\u021bii terestre suplimentare. Se preconizeaz\u0103 c\u0103, \u00een cursul anului 2014, \u0219ase sateli\u021bi se vor al\u0103tura celor patru existente, astfel \u00eenc\u00e2t serviciile opera\u021bionale ale sistemului Galileo s\u0103 poat\u0103 fi lansate p\u00e2n\u0103 la sf\u00e2r\u0219itul anului!<\/p>","protected":false},"excerpt":{"rendered":"
