Information Fusion Technology In The Integrated Navigation System

Information fusion technology has been a hot research field since 1980.This paperstudies information fusion problem in SINS/GPS integrated navigation system. TheStrapdown-Intertial Navigation system (SINS) and Gloable Position System (GPS) arerespectively discussed in this paper. At the beginning. The thesis has a detailed discussionon SINS and GPS, elaborating the parts of each system, principles of positioning, mistakemodel and model calculating, and accounting for the necessity of combing the SINS andGPS and how they are combined. Then, this paper systemtieally introduces some theory ofmulti-sensor Information Fusion, include the conception, the theory model and thecorrelate arithmetic of this Information Fusion technology. On this basis, SINS/GPSintegrated navigation system is researched and analyzed with information fusion. Thispaper establishes the mathematical model of the position, the speed integrated navigationsystem in SINS/GPS, and realized SINS and GPS integrated navigation using the kalmanfiltering technology, Finally, through the simulation experiment, confirmed the applicationfeasibility of the information fusion technology in the integrated navigation system.
