Proposal of Indoor Spatial Coordinate Definition Method and Compact Detection Module Using Fifth-Generation Mobile Communication System and Sensors

This research combines ranging information in ultra-wideband with structural-map information, geomagnetic information, and acceleration-sensor information to define and detect spatial coordinates. The definition method was shown to be effective even in indoor environments, and its effectivity was demonstrated using a small detection module as a detection method. The results of this research suggest the potential of the proposed method in defining spatial coordinates indoors.
