Аннотация:Purpose effective functioning of unmanned vehicles demands to process large amounts of various data. In order to systemize such data processing special so-called data fusion architectures are used (e.g. JDL, Waterfall, Boyd etc.). However, those have some shortages restricting their wide usage. A goal of this paper is to develop a new date fusion architecture which could be used on board of unmanned vehicles. Result this paper presents new hierarchical date fusion architecture for unmanned vehicles. This architecture has some advantages in comparison to those already in use. Practical results the developed data fusion architecture can be used for building complex data fusion systems on board of unmanned vehicles as well as of group of vehicles and even of systems of higher hierarchy.
