Abstract:
A radio interference avoidance system (1) has a processor in a detection system (11) which receives real time inputs from various sensors (12-16). The processor dynamically determines if a craft (for example, ship) movable network (19) is within an interference distance of a fixed network. It uses real time craft position data relative to fixed network position and also radiation characteristic data for both the movable (19) and fixed networks.
