Il est essentiel pour garantir un d\u00e9ploiement correct et rapide des moyens, tout en constituant un outil permettant de v\u00e9rifier la bonne ex\u00e9cution des services. Arriver sur les lieux d\u2019une urgence tout en manquant l\u2019emplacement de 30 pieds, soit 10 m\u00e8tres, peut se traduire par une perte de plusieurs minutes sur le temps d\u2019intervention. L\u2019absence d\u2019informations v\u00e9rifiables sur la localisation en cas de litige li\u00e9 \u00e0 un incident peut entra\u00eener une responsabilit\u00e9 civile.   <\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Le GNSS est d\u00e9sormais int\u00e9gr\u00e9 de s\u00e9rie dans de nombreux concentrateurs sans fil mobiles utilis\u00e9s dans les v\u00e9hicules d&#8217;urgence, tels que le routeur sans fil Ericsson Cradlepoint R1900 ; toutefois, les fonctionnalit\u00e9s habituelles de ces appareils pr\u00e9sentent les probl\u00e8mes suivants :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Probabilit\u00e9 d&#8217;erreur circulaire (CEP) de 3 m (en g\u00e9n\u00e9ral, 50 % des positions indiqu\u00e9es se situent dans un rayon de 3 m ; cette pr\u00e9cision est faible) ;<\/li>\n\n\n\n<li>une impr\u00e9cision excessive dans les zones sujettes aux trajets multiples (canyons urbains profonds provoquant des r\u00e9flexions du signal GNSS) ; et<\/li>\n\n\n\n<li>perte de fonctionnalit\u00e9 dans les environnements o\u00f9 le GNSS est indisponible (sous les viaducs, dans les parkings \u00e0 \u00e9tages).  <\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div><\/div><\/div>\n\n<div class=\"tbk-hydrate-component\" data-cid=\"924aa9a8-4808-4d25-b2e1-2a88fd02a60d\" data-component=\"Spacer\"><div class=\"calian-spacer wp-block-calian-com-components-calian-spacer\"><\/div><\/div>\n\n<div class=\"tbk-hydrate-component\" data-cid=\"480a0a51-23f0-44f1-8511-eba2b96ed8f4\" data-component=\"CalianContainer\"><div class=\"calian-container wp-block-calian-com-components-calian-container\"><div>\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"wp-block-paragraph\">D\u00e8s sa mise en service, le CEP peut d\u00e9j\u00e0 vous situer \u00e0 une all\u00e9e de votre destination.
