Design and Implementation of Hybrid Indoor Positioning System
The complexity of the indoor environment and the interference of buildings on the signal make out-door positioning such as GPS unable to accurately act on the indoor environment.Therefore,this paper proposes a hybrid indoor positioning system to improve the positioning accuracy,which can more intuitively reflect the location information of the location and reduce the time required for positioning to a certain extent.This paper simply studies the realization method of hybrid positioning and the factors that affect the positioning accuracy through the positio-ning experiment in a residential building.The positioning accuracy is affected by the density of points recorded in the database,the signal attenuation coefficient,the change of indoor environment and other factors.
