Abstract: Survivability is one of the technical indicators, which needed to consider in the highest priority, in the design and use of Unmanned Aerial Vehicle (UAV). According to the requirements of real-time display of situation and visual expression of analysis results in modern battlefield simulation, UAV survivability analysis system was developed with MapX component technology. First the primary frame and characteristics of MapX were introduced briefly. The function and composition of UAV survivability analysis system were discussed. And the module partition and program flow of system were given. Then the functions of war zone map display-roaming-zooming, combat scenario and display and process of survivability data with MapX technology in VC++ environment were analyzed in detail. Finally the simulation examples of survivability analysis were given. Simulation experiments indicate that the battlefield geographic environment of UAV is factually, vividly and dynamically displayed in the system. It is convenient to analyze the influence factors on survivability.
