Design of Integrated Navigation System Based on Information Fusion Technology for the Intelligent Transportation System

In recent years there has been a major upsurge of interest in the integrated global positioning system (GPS)/inertial navigation system (INS) as a cost-effective way of providing accurate and reliable navigation aid for civil and military vehicles. This thesis discusses the technology problem and calculation methods of GPS/INS integrated navigation system. The GPS/INS integrated navigation system based on information fusion technology and a multi-sensor information fusion algorithm based on federal Kalman filter is analyzed in detail. The federal KF algorithm suitable for this application is also developed; and preliminary computer simulation results are given and the simulation results show that Kalman filter can deal with information fusion for the GPS/INS integrated system
