Remote Piloted Aircraft Systems (RPAS) are operating in highly critical contexts and carry out a wide collection of complex mission tasks through the use of sensors. In this paper, we present a new agent-based architecture that handles sensors of these platforms. Today, the requirements of the platform in terms of autonomy, modularity, ro-bustness and reactivity as well as the industrial constraints call for the design of a new multifunction system architecture. Such a design may rely on multi-agent paradigm since it is modular by design and the agents naturally bring autonomy and pro-activity to the system. This paper presents new and original contributions: (1) an original agentification of the system in the form of a multi-agent architecture that helps to capture the dynamic of the environment; (2) agents that generates plans of tasks according to the resources (e.g. the sensors) he needs; (3) a scheduler that handles the plans of tasks issued by the agents in order to provide an efficient scheduling of sensors.
