Abstract

Nowadays, positioning systems and localization techniques have an outstanding application and prominence to reality. In recent times many studies have been concentrated on two localization systems: Inertial Navigation System (INS) and Wi-Fi positioning system (WiPs/WFPS). INS is not much used mainly because of its low reliability on cheaper devices. WFPS is, instead, a recently developed system that presents an appreciable ductility to many environments and a respectable reliability. Techniques and algorithms have been studied to improve precision in localization exploiting more systems to provide a better result. These are taken into consideration by the proposed work which suggests a logic to obtain an as accurate as possible method to retrieve a reliable individuation of devices exploiting and combining WFPS and INS (Inertial Navigation System) in a Wi-Fi provided space. The data obtained are two distances matrices and two errors array referring to the approximate distance among devices in the space selected. To reach the purpose, the arrays of errors are for first normalized and then Wi-Fi and INS matrices are symmetrized taking in more consideration devices with less margin of error, these last are then merged in order to obtain a more accurate distances matrix.
