Research Of Accuracy And Consummation In GPS/Beidou Application System

The system of satellite navigation has been widely applied to our social life. For example, the system can be used in industry, fishery, civil engineering, geography information industries, weather forecast, telecommunication, traveling, entertainment and so on, which can totally emonstrate its huge application potential .Because the basic function of satellite navigation is that it can provide real-time position, speed and time information, no matter what platform it is the accuracy and consummation of this system will directly influence the efficiency and effect of each platform. This paper has studied the accuracy and consummation technology in the GPS/ Beidou double system. Several algorithms to enhance the precision of such systems were proposed and carried out in the research.The first chapter introduces the development of modern satellite navigation technology, as well as GPS/ Beidou double system. Primary research work and conlusions were stated;After the introduction of the GPS system's localization principle, the error source analysis and the processing method, the second chapter focuses on the location principle and the error analysis of Beidou system. The location result jump question caused by time drifting and reference beam cut was studied here. The simulation result is set out at the end of this chapter;The third chapter studied BeiDou location deviation calibration technology based on the GPS location result assistance system. The calendar search calibration and the direct location calibration algorithm was proposed and carried out in this research;The fourth chapter studied GPS macrozonality enhancement difference location and consummation examination technology based on the Beidou system assistance. Besides, the concrete realization of such system was proposed here, including the composition of user machine based on this technology, the principle of work, the performance test result and its application as well.
