Zusammenfassung: | To provide a positioning system that can perform highly accurate real-time positioning of a positioning object even when the positioning object moves in a broad area.SOLUTION: A server is configured to: receive observation information generated by a reference station 40 receiving a radio wave of an artificial satellite 50, from a plurality of reference stations 40 arranged respectively in a plurality of known referent points; prepare positioning correction information on the basis of the observation information received from the reference station 40 as to each of the plurality of reference stations 40; store the positioning correction information in association with location information on the reference station 40; receive the observation information generated by the reference station 40 receiving the radio wave of the artificial satellite 50, from a positioning object 20; select a plurality of reference stations 40 arranged at a location close to the positioning object 20 on the basis of the observation information; calculate a plurality of pieces of location information on the positioning object 20 on the basis of the observation information on a plurality of selected reference stations 40, positioning correction information thereon and location information thereon, and observation information on the positioning object 20; and select a calculation result on any one piece of location information from the calculation results of the plurality of pieces of location information.SELECTED DRAWING: Figure 1
【課題】測位対象が広域エリアを移動する場合でも、測位対象の高精度リアルタイム測位を行うことができる測位システムを提供する。【解決手段】複数の既知の基準点それぞれに配置された複数の基準局40から、人工衛星50の電波を基準局40が受信して生成した観測情報を受信する。複数の基準局40それぞれについて基準局40から受信した前記観測情報に基づいて測位補正情報を作成し、基準局40の位置情報と関連付けて記憶する。前記基準局40が人工衛星50の電波を受信して生成した観測情報を測位対象20から受信し、その観測情報に基づいて測位対象20に近い位置に配置されている複数の基準局40を選択する。選択した複数の基準局40の観測情報、測位補正情報及び位置情報と測位対象20の観測情報とに基づいて測位対象20の複数の位置情報を計算し、複数の位置情報の計算結果から、いずれか一つの位置情報の計算結果を選択する。【選択図】図1 |
