Abstract

Selon l'invention, une unité de calcul de position (23) calcule une position actuelle sur la base d'un signal reçu par une unité de réception GPS (système mondial de localisation) (21) et provenant d'un satellite GPS (22). Une unité d'émission (24) émet un signal de détresse comprenant une information de détresse fixée au préalable ainsi qu'une information de position actuelle calculée par l'unité de calcul de position (23). La taille et le poids de l'émetteur de signaux urgents (20), faisant appel à un émetteur d'algorithme, peuvent être réduits de sorte qu'il soit pratique à transporter. Etant donné que l'unité d'émission (24) émet un signal de détresse sur la base d'une régulation de signaux de détresse SMDSM, il est possible d'utiliser un système de sauvetage SMDSM pour sauver les victimes, afin de permettre des opérations de sauvetage rapides dans le monde entier.
