| Zusammenfassung: | PROBLEM TO BE SOLVED: To shorten calculation time for conversion by converting a positional coordinate of a reception antenna available as a measured position with GNSS (global navigation satellite system) to an accurate train position.SOLUTION: A route distance M and a positional coordinate Q of an antenna locus point B which is a position of a reception antenna 14 under a condition in which any of reference points E1, E2 specified at a vehicle 20 agrees with orbit center points A1-A4 specified on an orbit center line 32 of a line are calculated, and based on a position measured with GNSS, a reference data is generated which is utilized when calculating a route distance of a vehicle.SELECTED DRAWING: Figure 4
【課題】ＧＮＳＳ（全世界的測位衛星システム）による測位位置として得られる受信アンテナの位置座標を、正確な列車位置に変換し、変換しようとする場合の演算時間の短縮化を図る。【解決手段】車両２０に定められた基準点Ｅ１，Ｅ２の何れかが線路の軌道中心線３２上に定められた軌道中心点Ａ１〜Ａ４に一致した状態での受信アンテナ１４の位置であるアンテナ軌跡点Ｂの位置座標Ｑと路線距離Ｍとを算出して、ＧＮＳＳで測位した測位位置をもとに車両の路線距離を算出するときに利用される参照用データを生成する。【選択図】図４ |
