PROBLEM TO BE SOLVED: To provide high accuracy position information required for automatic steering or the like of a traveling movable object in a wide area and at low cost and to accumulate and utilize various traveling movable object generation information integrated with the high accuracy position information.SOLUTION: A plurality of arbitrary fixed base stations B are provided around a traveling movable object Rv in a wide area. A central center C generates high accuracy position correction information in accordance with correlation positions between the traveling movable object Rv and the plurality of arbitrary fixed base stations B and provides a system terminal T with the high accuracy position correction information. The system terminal T receives position correction information from the central center C, transmits the position correction information to a guidance device G mounted on the traveling movable object Rv, and the guidance device G generates a position of the traveling movable object Rv on the traveling movable object Rv with high accuracy. The system terminal T can integrate the high accuracy position information generated by the guidance device G and various sensor information, a travel track, or the like generated and recorded by the traveling movable object Rv, transmit and accumulate them in a designation center, and extract and utilize designation information from among the accumulated information.SELECTED DRAWING: Figure 1
【課題】走行移動体の自動操舵等に必要な高精度位置情報を広域において低コストで提供するとともに高精度位置情報と統合された各種走行移動体生成情報を集積・活用する。【解決手段】走行移動体Rvの周辺には広域に複数・任意の固定基地局Bが設けられる。中央センタCは走行移動体Rvと複数・任意の固定基地局Bの相関位置に応じ高精度位置補正情報を生成しシステム端末Tに供給する。システム端末Tは、中央センタCからの位置補正情報を受信して走行移動体Rv上に搭載されるガイダンス装置Gに送信し、ガイダンス装置Gは走行移動体Rv上で走行移動体Rvの位置を高精度に生成する。システム端末Tは、ガイダンス装置Gが生成した高精度位置情報と走行移動体Rvが生成・記録した各種センサ情報、走行軌跡等を統合し指定センタに送信・蓄積すると共に蓄積した情報の中から指定情報を抽出活用できる。【選択図】図1
