Az ESA az 1970-es \u00e9vek \u00f3ta foglalkozik m\u0171holdas t\u00e1vk\u00f6zl\u00e9ssel. M\u00e1r 1980-ban is az \u201eOrbital Test Satellite\u201d nev\u0171 m\u0171holdj\u00e1t haszn\u00e1lt\u00e1k videokapcsolatok l\u00e9trehoz\u00e1s\u00e1ra n\u00e9metorsz\u00e1gi \u00e9s brit csoportok k\u00f6z\u00f6tt. Emellett v\u00e9szh\u00edv\u00e1sokat is tov\u00e1bb\u00edtott, miut\u00e1n egy t\u0171zv\u00e9sz megsemmis\u00edtette a lyoni f\u00f6ldi rendszert.<\/p>\n<\/div>\n

Nem sokkal k\u00e9s\u0151bb a Marecs nev\u0171 m\u0171hold \u00e1tt\u00f6r\u00e9st hozott a mobil t\u00e1vk\u00f6zl\u00e9s ter\u00fclet\u00e9n.
