High-accuracy Positioning Algorithm Based on UWB

摘要：

　　In the indoor positioning,it proposes a line to approximate hyperbola positioning algorithm based on ultra-wideband(UWB)aiming at the problems of low-accuracy positioning,non-line-of-sight(NLOS)phenomenon and multipath propagation in the precise positioning of mobile tags.The paper a method of using some lines to approximate hyperbola.It can convert quadratic hyperbolic equation into linear equation.Then it can achieve the high-accuracy position combining the time difference of arrival(TDOA)and triangle centroid position algorithm.According to MATLAB simulation,the average distance error of the three-line approximate algorithm is 23.7cm,the average distance error of the three-and-four-line approximate positioning algorithm is 17.7cm,and the average distance error of the five-line approximate positioning algorithm is 12.9cm.In the case of ensuring positioning accuracy,the Chan algorithm runs for a period of 14.5s.The maximum time is 7.9s for the algorithm to run one cycle,and the complexity of the algorithm is greatly reduced.
