Design And Implementation Of Beidou Satellite Positioning/navigation System Based On GIS

With the continuous development of information technology, the application of spatial information technology is becoming more and more widely. Geographic information system(GIS), which is the core of the space information technology, can satisfy the people demand for management and analysis of spatial data, At the same time, with the promotion of China’s beidou Navigation System, development example based on this System is also more and more. Therefore, GIS technology combined with beidou navigation positioning technology has broad application prospects.This dissertation mainly researches the GIS technology in the application of the beidou navigation and positioning system. It is introduced that the principle of beidou navigation positioning system to realize the collection of vehicle terminal information data. And then the classification of GF data is talked, the pretreatment technology of GF data is analyzed. This dissertation studies the basic principle of GIS system, analyzes the development process of ArcGIS Engine. The dissertation completes the real-time display of the vehicle, realizing the functions of path preservation, track playback, space attribute information query, eagle eye, etc.The project is based on the.NET platform, using C# language to realize development of the entire system, combined with beidou navigation module and Access database to complete the data acquisition and storage, and the spatial database to storage attribute information of high resolution satellite images. By calling the related controls and interface of ArcGIS Engine component library, vehicle positioning in database is shown on the map and playback of vehicle track can carry on at any time. Vehicle real-time monitoring is completed at last.GIS map used in this project comes from GF data. GF satellite in the defense, intelligent transportation, environment and other fields has a very wide application, being independent research and development of our country. It has very important significance to improve the level of spatial information.
