Research on pedestrian cooperative localization based on inertial navigation and ultra-wideband
Based on inertial navigation and ultra-wideband(UWB),this paper studies the pedestrian cooperative localization technology in the case of GPS signal interference.In this paper,a cooperative navigation algorithm is used,which can obtain the position information of single person based on the calculation of pedestrian navigation,and on the basis of the relative observation value obtained by UWB ranging,the extended Kalman filter algorithm is used to interactively fuse the position information of each pedestrian,and finally the ideal position information of the target is obtained.The pedestrian navigation experiments show that this method can improve the positioning accuracy of the system,and further strengthen the stability and reliability of the system.
