DETERMINATION SYSTEM, DETERMINATION METHOD, DETERMINATION DEVICE AND MEASUREMENT DEVICE
To eliminate influence of environmental noise to ensure accuracy of position determination.SOLUTION: There is provided a determination system which comprises: a first antenna arranged inside a vehicle compartment of a mobile body; a second antenna arranged outside the vehicle compartment of the mobile body; a third antenna mounted on a portable device carried by a user of the mobile body; and a determination unit that determines a position of the portable device based on wireless communication conforming to a prescribed communication standard between the first antenna and the third antenna, and between the second antenna and the third antenna, where the determination unit determines whether or not to retry the position determination based on a measurement result of environmental noise transmitted by the third antenna.SELECTED DRAWING: Figure 3
【課題】環境ノイズの影響を排除し位置判定の精度を担保する。【解決手段】移動体の車室内に配置される第１のアンテナと、前記移動体の車室外に配置される第２のアンテナと、前記移動体のユーザに携帯されるポータブル機器に搭載される第３のアンテナと、前記第１のアンテナと前記第３のアンテナとの間、および前記第２のアンテナと前記第３のアンテナとの間における規定の通信規格に準拠した無線通信に基づいて、前記ポータブル機器の位置判定を行う判定部と、を備え、前記判定部は、前記第３のアンテナが送信する環境ノイズの測定結果に基づいて、前記位置判定のリトライの要否を判定する、判定システムが提供される。【選択図】図３
