Research on indoor and outdoor seamless positioning system based on multi-tech integration
With the vigorous development of modern industry,positioning application is becom-ing more and more popular,and indoor and outdoor integration positioning will become an in-evitable development trend.However,indoor positioning and outdoor positioning are relatively independent.In the complex environment of the indoor and outdoor border area,the delay and frequent switching phenomenon in the process of indoor and outdoor switching have not been effectively solved,which greatly affects the user experience.The paper proposes a scheme of in-tegrating indoor and outdoor positioning technology,combining PDR with GNSS,5G,UWB,pseudo satellite and other positioning methods,to achieve"seamless connection"between indoor and outdoor positioning,so that users move indoor and outdoor mobile without erception.Solve the fluctuation phenomenon and the possibility of misjudgment in the positioning technology switch in the indoor and outdoor middle zone,so as to achieve a more stable and reli-able location service.
