Indoor positioning method based on inertial data, RSSI and compass from handheld smart-device

A novel indoor positioning method based on user's inertial measurements, measured radio signal strength indicator (RSSI), and compass readings is presented. Based on distance travelled derived from inertial measurements and heading direction from compass readings, the user's position is initially computed using Dead-Reckoning (DR) method. Then the estimated position, under certain condition, will be further corrected based on the RSSI and compass reading. Experiment results are presented to show the feasibility of the proposed method.
