Seules les stations dont une position a été reçue sont affichées ici. Les statistiques de distances montrent quelques bonds longs, car certains digipeaters ne se sont pas correctement ajoutés au chemin. S’il vous plait vérifiez les paquets bruts.

Cette page affiche en temps réel les informations recueillies par le système de suivi automatique de position (APRS) Automatic Position Reporting System sur le réseau Internet (APRS-IS). L'APRS est utilisé par les radioamateurs afin de transmettre en temps réel des informations de position, des données météorologiques, de la télémétrie et des messages par les ondes radio. Un véhicule équipé d'un récepteur GPS , d'un émetteur VHF ou HF (émetteur ?) et d'un petit appareil appelé "tracker", transmet sa position, sa vitesse et son cap dans un petit paquet de données, qui sont ensuite reçus par la plus proche passerelle internet (iGate) qui renvoie le paquet sur Internet. Les systèmes connectés à Internet peuvent envoyer des informations sur le réseau APRS-IS sans émetteur radio, ou recueillir et afficher des informations transmises à travers le monde.
