Juba 1980. aastal kasutati selle orbitaalset katsesatelliiti videolinkide loomiseks Saksamaa ja \u00dchendkuningriigi r\u00fchmade vahel. Samuti edastas see h\u00e4daabik\u00f5nesid p\u00e4rast seda, kui tulekahju h\u00e4vitas Lyoni maapealse s\u00fcsteemi.<\/p>\n<\/div>\n<p>Varsti p\u00e4rast seda t\u00f5i satelliit nimega Marecs kaasa l\u00e4bimurde mobiilsides.

Iga\u00fcks neist suutis edastada 12 000 telefoniliini ja 10 telekanalit kogu Euroopas.<\/p>\n<p>Edusammud satelliidilt katusele paigaldatud antennidele suunatud otsesaadete edastamisel saavutati 1989. aastal t\u00e4nu ESA satelliidile Olympus.
