Tous les satellites de télécommunication (transmission de données, d'images et de sons) sont placés sur une orbite circulaire équatoriale. La raison en est simple : ainsi placés, ils peuvent facilement «arroser» différentes zones du globe et relayer des données provenant de deux points très éloignés. C'est cette localisation équatoriale qui explique l'orientation au sud d'une antenne parabolique installée depuis la France et plus globalement l'hémisphère nord. 1, record 1, French, - orbite%20circulaire%20%C3%A9quatoriale
