Realization of Intelligent Low Altitude Penetration Employing GPS/MAP Technology

A low altitude penetration system plays an important role in modern war and is developed towards an intelligent and autonomic one. In this paper,some key technology to realize an intelligent low altitude penetration employing a global positioning system (GPS) and an electronic digital.map(MAP)is studied. First the definition of the intelligent low altitude penetration is investigated,and its overall design scheme and operation theory achieved by GPS/MAP technology is derived. Secondly the design of electronic digital map is presented, including the functional design of MAP,database design,and hardware and software design. Thirdly the linking plan of MAP with GPS and automatic flight control system (AFCS)is given, A circuit diagram of GPS and MAP linking interface is presented. Finally,the design of an expert system of the intelligent low altitude penetration is investigated. The functions and the control logic of the expert system are derived,and the design requirements of the optimal penetrating path and the selective principle of the optimal penetration mode are presented too. Comparing with the adoption of a terrain radar to realize the traditional low altitude penetration, the adoption of GPS and MAP to achieve the intelligent low altitude penetration is much advanced in performance and technology.
