ajst-7560	Wang, Fei	Analysis of UWB Indoor Positioning Accuracy Based on TW-TOF	2023	4	.pdf	application/pdf	2092	92	50	The specific values of UWB positioning accuracy were obtained: the maximum UWB positioning error was 1.09 m, the average positioning error was 0.21 m, the standard deviation of positioning error was 0.15 m, and the variance of ranging error was 0.02 m. The accuracy reliability of UWB positioning error less than 0.2 m was 54.12%, and the accuracy reliability of UWB positioning error less than 0.4 m was 87.81%. In order to study the UWB in indoor high-precision ranging and positioning, this paper adopts the popular UWB devices in the market, conducts ranging and positioning experiments using the TOA positioning method of bidirectional ranging TW-TOF, and solves the positioning coordinates using the least squares algorithm and Gauss-Newton iterative algorithm, and analyzes the accuracy of the positioning results of the simulation experiments to prove the accuracy and reliability of UWB positioning.	cache/ajst-7560.pdf	txt/ajst-7560.txt
