Research And Implementation Of Foreign Space Intelligence Information System

With the rapid development of science and technology,information has become an important resource in modern society.Information technology is the fastest growing technology in half a century,which promotes a new technology revolution.As a high-tech and burgeoning industry,information has developed quickly and rapid influenced all over the world.Information has turned into the core industry that drives the economic development.To some extent,it is a symbol of a country's comprehensive power.The fast development of space technology relies on the support of the information technology.Space intelligence information has played a important role in space program,the selection of aerospace route and application and promotion of the new technology.Nowadays,the exploration of space technology is deeping,various powers all hope to grasp the “Confidential” and resource further,and are enthusiastic about the development of satellites and rockets,and exploration of outer space.We are in a special period of rapid development of network and information,in order to effectively deal with large-scale information,this thesis is based on the project of "foreign space intelligence information system".the investment in space not only can obtain important strategic interests and economic benefits,but also shows that the importance of“command of the space” in national development and security.This project aim at“ the structured of knowledge,the productized of outcome”,based on the accumulation of many years of intelligence facts,research and development software service platform for internal research and commercial.According to foreign space information data types,complex call relationship between various databases,this thesis summarizes the business needs,through data classification,data encoding,quality control and standardized management,all kinds of space information data are divided into 15 databases.Under the control of unified standard and quality assurance system,building a user oriented data service,including data query,retrieval,statistics,data visualization and download and application oriented data service.The system uses the B/S network structure model,clients can use the browser to obtain services conveniently,is a Web application system based on LAMP framework.The user interaction of the system uses the CodeIgniter framework,and the current front-end technology(HTML+CSS+JQuery+Ajax+Highcharts,etc.)to obtain a better user experience and page effect.The development of CodeIgnite based on MVC(model view controller)design pattern,this design can separate system into control part,view,part,and logic part,greatly increasing the simplicity of research and development,strengthen the ability to expand.The core functions of backend are implemented in PHP,including data retrieval,data statistics,data visualization,operation monitoring and user permissions.In order to store information effectively,we use the MySQL database to store data,which has provided a guarantee for the security of data storage..This thesis studied the space information system research situation on a world-wide scale,researched on the core technology,including MVC model,system structure and data flow of CodeIgniter,as well as some front-end technology.Then divided users into different groups,according to the characteristics of the user groups.Based on the research conclusion,the thesis discusses the data table,functional module and business logic.At the end of the thesis,the present situation of the system is illustrated,and its effectiveness is demonstrated.
