Dependencies:   MODSERIAL SDBlockDevice GPS

Forschungsstand und Theoretische Grundlage

Die Bestandteile der Hardware, die das Projekt gebraucht wird, bestehen aus drei Komponente ein Mikrocontroller Board, eine GPS Antenne und ein SIM Modul. GPS basiert auf Satelliten, die mit codierten Radiosignalen ständig ihre aktuelle Position und genaue Uhrzeit ausstrahlen. Aus den Signallaufzeiten können eine GPS Antenne ihre eigene Position und Geschwindigkeit berechnen. Diese GPS Antenne sollte die Daten der Objektposition aus Satelliten auf dem Board gespeichert werden. Diese Daten wurden noch weiter durch eine SIM Module nach GMS Turm und dann per SMS Nachrichten an Handy gesendet. Möglicherweise können diese Daten auch an Webanwendung nach der Sendung an GMS Turm geschickt werden.
