Mobile System for Indoor Localization Using Positioning and Route Correction
Abstract
Indoor positioning systems aims to indicate the location of a device indoors, where the GPS signal is weak or even non-existent. This work presents a system capable of determining the position and trajectory of a user in indoor environments using the magnetometer and step sensors. The system also corrects the position and trajectory originally obtained. Two strategies were used determine the position: the first using only the GPS signal and the second using a combination of sensors of a cell phone. Also, the original data from the sensors were compared with the data after the correction of position and trajectory were made. The tests were performed in the first ㎀oor of a building composed by open and closed areas. The best results were achieved when using the magnetometer and step sensors.
