English: VHF gdmss
Français : Le portatif SMDSM est un émetteur récepteur mobile VHF (très haute fréquence), petit, étanche, léger, utilisable par un naufragé sans compétence (mode d'emploi au dos de l'appareil), avoir des boutons suffisamment gros pour être manipulés par des personnes portant des gants (combinaisons de survie) et résister aux chocs (chute d'un mètre), utilisant au minimum deux canaux : 16 et 6 en mode G3E. Plusieurs niveaux de puissance sont disponibles, celle-ci doit pouvoir être réduite entre 0,25 W à 1 W. Son autonomie est de 8 heures, sur la base de 10 secondes d'émission et de 50 secondes de réception par minute. Il doit posséder un étiquetage comportant la date de validité de la pile. Le portatif SMDSM VHF est utilisé pour les cas d’interconnexions, de coordination de la recherche et du sauvetage maritimes et l'interconnexion aéronefs à navires. |
