英文摘要	Wi-Fi indoor positioning algorithms experience large positioning error and low stability when continuously positioning terminals that are on the move. This paper proposes a novel indoor continuous positioning algorithm that is on the move, fusing sensors and Wi-Fi on smartphones. The main innovative points include an improved Wi-Fi positioning algorithm and a novel positioning fusion algorithm named the Trust Chain Positioning Fusion (TCPF) algorithm. The improved Wi-Fi positioning algorithm was designed based on the properties of Wi-Fi signals on the move, which are found in a novel quasi-dynamic Wi-Fi signal experiment. The TCPF algorithm is proposed to realize the process-level fusion of Wi-Fi and Pedestrians Dead Reckoning (PDR) positioning, including three parts: trusted point determination, trust state and positioning fusion algorithm. An experiment is carried out for verification in a typical indoor environment, and the average positioning error on the move is 1.36 m, a decrease of 28.8% compared to an existing algorithm. The results show that the proposed algorithm can effectively reduce the influence caused by the unstable Wi-Fi signals, and improve the accuracy and stability of indoor continuous positioning on the move.; Navigation and Location-based service (NAL) Lab, Peking University; SCI(E); EI; PubMed; ARTICLE; huaiyuli@pku.edu.cn; xwchen@pku.edu.cn; jinggf@most.cn; pkuwangy@pku.edu.cn; caoyanfeng@cate.casc; gisor.lee@pku.edu.cn; 1501110619@pku.edu.cn; hxiao@pku.edu.cn; 12; 31244-31267; 15
