ADAPTIVE POSITIONING METHOD, DEVICE, AND SYSTEM BY INTEGRATION OF TOA (TIME OF ARRIVAL) AND RSS (RECEIVED SIGNAL STRENGTH)

摘要

PROBLEM TO BE SOLVED: To provide an adaptive positioning method, device, and system having adaptability, reliability, high accuracy, extensibility, and low cost.;SOLUTION: The device includes an observation result collector for collecting a TOA result and RSS result of a signal transmitted from an object, a TOA result counter for determining the number of the collected TOA results, and a position computer for selecting a position calculation method of a mobile body based on the input number of TOA results and calculating the position of the mobile body by using the selected calculation method. The adaptive positioning method can be adaptively selected based on the number of the TOA results.;COPYRIGHT: (C)2009,JPO&INPIT
