Abstract: The present invention concerns a mission system that comprises at least an operator station suitable for being operated by a human operator, at least a mission agent suitable, in use, for being used to carry out an operational mission and a mission control system. The mission control system comprises a server mission software module operatively coupled to the operator station and a client mission software module operatively coupled to the mission agent. The server mission software module is suitable, in use, for being operated by a human operator to define the operational mission by means of a mission plan comprising at least one mission activity to be carried out and at least one operating rule for carrying out the mission activity. The server mission software module is also able, in use, to communicate the mission plan to the mission agent.
