Abstract

In order to solve the problem of indoor target movement autonomous positioning error accumulation, this paper proposes a method of the RSST assisted positioning error compensation. In the first place, the identification card position is determined using optimizing the distance and orientation between the main station and the auxiliary station. Secondly, the Auxiliary correction of time positioning error is proceeding by RSSI measured value. Finally, the singular data are corrected and least squares processed through multiple measurements to reduce the influence of measurement data fluctuation on positioning. Practical application has been carried out in the corridor environment consisting of 1 main station,2 auxiliary stations and 20 terminal nodes and the direct-vision distance is 200m. The results show that the method reduces the errors of environment, scattering and system. Compared with the positioning error of point-to-point ranging in the corridor environment, the error decreases from 12m to 3m by 75%. Compared with the corridor environment 1, the location error of main station and auxiliary station is reduced from 15m to 3m by 80%.
