In order to solve the problem of pedestrian positioning in the indoor environment, this paper proposes a high-precision indoor pedestrian positioning system (HPIPS) based on smart phones.  ...  mapping relationship between indoor spatial position and Wi-Fi RTT (round-trip time) ranging information is proposed.  ...  Filter-based target tracking and positioning process. Figure 3 . 3 Figure 3. Structure diagram of high-precision indoor pedestrian positioning system (HPIPS). Figure 4 . 4 Figure 4.  ...
