Patent ID: 10359503

Abstract:
The present invention provides a position estimation apparatus, a position estimation system, and a position estimation method that can estimate, with high accuracy, the position of a wireless device, the position of which is unknown, as well as a recording medium for position estimation. The position estimation apparatus comprises: a data collection means for collecting measurement data related to an inter-device distance between one wireless device and another wireless device, the inter-device distance being measured by the one wireless device, and measurement data related to the reliability of the inter-device distance between the one wireless device and the other wireless device, the reliability being calculated by the one wireless device; and a wireless-device position estimation means for estimating the position of a wireless device, the position of which is unknown, on the basis of the measurement data collected by the data collection means and the previously collected measurement data related to the measured inter-device distance between the one wireless device and the other wireless device, and the reliability of the inter-device distance.
