Abstract

　本発明は、精度の高い伝搬遅延時間を測定できる伝搬遅延時間測定システムを提供することを目的とする。 　伝搬遅延時間測定システム１００は、送信時刻を格納した測定用パケットａを複数連続して送信する伝搬遅延時間測定装置１１０と、伝搬遅延時間測定装置１１０から送信された測定用パケットａを伝搬遅延時間測定装置１１０に返送する応答装置１２０と、を有する伝搬遅延時間測定システム１００であって、伝搬遅延時間測定装置１１０は、応答装置１２０から返送された測定用パケットａを受信し、受信した測定用パケットａのうちの少なくともいずれか１つを用いて伝搬遅延時間測定装置１１０と応答装置１２０との間の伝搬遅延時間を測定する。
