Les informations pr\u00e9cises sur la position des avions, bateaux, trains et autres formes de transport sont vitales dans le monde fr\u00e9n\u00e9tique d\u2019aujourd\u2019hui. Par exemple, les h\u00e9licopt\u00e8res qui vont secourir les personnes accident\u00e9es en montagne doivent trouver la plate-forme d\u2019atterrissage de l\u2019h\u00f4pital m\u00eame s\u2019il y a du brouillard ou de la neige et si le pilote n\u2019a qu\u2019une visibilit\u00e9 limit\u00e9e. EGNOS est un syst\u00e8me europ\u00e9en qui rend la navigation par satellite suffisamment fiable et pr\u00e9cise pour justement parvenir \u00e0 ce genre de man\u0153uvres.<\/p>\n<\/div>\n

EGNOS est compos\u00e9 de trois satellites g\u00e9ostationnaires et d\u2019un r\u00e9seau de plus de quarante stations au sol r\u00e9parties partout en Europe. Quatre centres de contr\u00f4le v\u00e9rifient la pr\u00e9cision des mesures de position envoy\u00e9es par chaque satellite GPS. Ces informations sont ensuite relay\u00e9es vers les r\u00e9cepteurs des utilisateurs via les trois satellites de communication. Les informations fournies par EGNOS assurent une pr\u00e9cision de position \u00e0 moins de deux m\u00e8tres pr\u00e8s, contre 5 \u00e0 10 m\u00e8tres avec le GPS seul.<\/p>\n

EGNOS est op\u00e9rationnel depuis octobre 2009. Il est particuli\u00e8rement utile pour les services de secours d\u2019urgence, comme la recherche et le sauvetage en montagne, et il est utilis\u00e9 par les corps de pompier, les ambulances, les forces de police et les services de secours aux sinistr\u00e9s.<\/p>","protected":false},"excerpt":{"rendered":"
