Claims (1)
- 航空機から送信された送信時刻、当該航空機の識別子、当該航空機の位置及び飛行データを含む信号を受信して処理する地上装置であって、
航空機から送信された送信時刻、当該航空機の識別子、当該航空機の位置及び飛行データを含む第1信号を送信した航空機の位置である第1送信位置から前記地上装置までの距離と、第1送信位置から移動後に当該航空機から送信された送信時刻、当該航空機の識別子、当該航空機の位置及び飛行データを含む第2信号を送信した当該航空機の位置である第2送信位置から前記地上装置までの距離とをそれぞれ求める距離特定手段と、
前記距離特定手段によって、第1送信位置から前記地上装置までの距離と第2送信位置から前記地上装置までの距離が複数組求められると、各組の第1送信位置から前記地上装置までの距離と第2送信位置から当該地上装置までの距離に対し、当該地上装置の位置の候補をそれぞれ特定するとともに、複数の位置の候補が特定されると、複数の位置の候補が一致する位置又は隣接する複数の位置の候補から求められる位置を当該地上装置の位置として当該地上装置の位置を特定する位置特定手段と、
を備えることを特徴とする地上装置。
