Position information that is multi-laterated from the distance information obtained using the received signal strengths collected from several access points are processed in a FKF to estimate the position of the target. Two approaches are presented to adjust the information-sharing coefficients of FKF using online measurements. The data collected on a test bed composed of four access points are used to assess and compare the performances of the proposed algorithms. It is shown that the estimation error can be improved considerably by adjusting the information-sharing coefficients online.eninfo:eu-repo/semantics/closedAccessSensorsKalman filtersSensor fusionMathematical modelSensor systemsPosition measurementLocation awarenessIndoor positioningKalman filtersensor fusionArticle53025308622WOS:00077005480005310.1109/JSEN.2021.30972492-s2.0-85110823145Q2Q1
