Design And Realization Of Scene Simulation System For Space Launch Measurement And Control Missions

In recent years,as space technology and space activities develop quickly in China,the frequency and difficulty of space launch,measurement and control missions have remarkably increased,posing higher demands for the informatization construction of space launch sites and making digital space launch site buildup a key aspect of space area.Utilizing advanced computer modeling and scene simulation techniques to develop the scene simulation system for space launch,measurement and control missions can combine the mission with resource management,environment and weather conditions,as well as handle and display various resources,mission procedures and results in real time and dynamically.In addition,this system supports the rehearsal,monitoring,and post-evaluation of the mission,thus serving as a direct,convenient,flexible and practical command tool and assistant decision-making system for the mission organization,management,resource allocation optimization and risk control of space launch,measurement and control missions.Therefore,this system is significant and valuable to ensure the success and enhance the efficiency of space missions.Against this background,this thesis focuses on the demands and procedures of the space launch,measurement and control mission,and uses 3-D modeling technique and data resource management method to design and realize the scene simulation system of space launch,measurement and control.The main research content is as follows: Firstly,the overall technical framework of the scene simulation system is designed,and then its composition and procedures are demonstrated and analyzed.Each module's function is described briefly.Secondly,the 3-D scene modeling technique is studied,and the modeling method and characteristics are described in detail from three aspects: terrain environment,space environment and 3-D entity modeling.Thirdly,as for the mission content and its characteristics of space launch,measurement and control,the script-based mission scenarios are generated.Moreover,the measurement and control resource and mission database are developed surrounding the problem of resource management and the mass data management.Fourthly,the space launch,measurement and control system is designed and developed based on the latest ViewTerra Visual development platform by utilizing the above modeling method.The system is initially applied to the mission analysis and demonstration of space launch site after the site installation and debugging,which shows verisimilar visual effects and obvious social benefits.
