Poleg tega je posredoval tudi nujne telefonske klice, ko je po\u017ear uni\u010dil zemeljski sistem v Lyonu.<\/p>\n<\/div>\n<p>Kmalu zatem je satelit z imenom Marecs prinesel preboj na podro\u010dju mobilnih telekomunikacij. Namesto nezanesljivega kratkovalovnega radia so ljudje lahko uporabljali satelitske telefone za klicanje z ladje na kopno.<\/p>\n<p>V poznih 80. letih in v 90. letih so izstrelili \u0161tiri satelite ECS. Vsak od njih je lahko obsegal 12.000 telefonskih povezav in 10 televizijskih kanalov po vsej Evropi.<\/p>\n<p>Napredek na podro\u010dju neposrednega oddajanja prek satelita na stre\u0161ne antene je prinesel satelit Olympus agencije ESA leta 1989. Satelit Olympus je bil uporabljen tudi za prvi prenos podatkov med dvema satelitoma.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2925\" data-credit=\"ESA - J.
