Abstract

La présente invention concerne un système de communication pour un véhicule aérien sans pilote, comprenant un véhicule aérien sans pilote, un premier dispositif de communication sans fil et un second dispositif de communication sans fil. Le premier dispositif de communication sans fil comprend un premier module de communication sans fil, et le véhicule aérien sans pilote comprend un second module de communication sans fil ; le premier module de communication sans fil est configuré pour recevoir un signal externe provenant du second module de communication sans fil, et envoyer le signal externe au véhicule aérien sans pilote au moyen d'un canal de liaison montante ; le second module de communication sans fil est configuré pour transmettre un signal d'image acquis au premier dispositif de communication sans fil au moyen d'un canal de liaison descendante ; le canal de liaison montante et le canal de liaison descendante sont situés dans la même bande de fréquence de communication. Selon des modes de réalisation de la présente invention, la fusion d'un trajet de communication d'image de liaison descendante et d'un trajet de communication de signalisation de commande de liaison montante est mise en oeuvre dans un scénario d'interaction à dispositifs multiples d'un véhicule aérien sans pilote, ce qui permet d'utiliser efficacement des ressources de fréquence et d'espace et de réduire les coûts matériels.
