Title:
位置推定装置、位置推定方法およびプログラム
Document Type and Number:
Japanese Patent JP5413335
Kind Code:
B2
Abstract:
An apparatus, method and computer program storage device cooperate to provide a quality position estimation of a mobile communication device by determining a reference area. The reference area includes the position of the mobile communication device as well as a plurality of transmitters. Transmitters that are detected as being outside of the reference area are excluded from contributing to the position estimate. The reference area is centered at a standard position, which may be a previous position or a GPS based position, for example. The range of the reference area includes a component that considers the range of a transmitter, as well as a GPS error or an estimated move distance of the mobile communication device.
