Like radiolocation, it is a type of radiodetermination. The basic principles are measurements from/to electric beacons, especially * directions, e.g. by bearing, radio phases or interferometry, * distances, e.g. ranging by measurement of travel times, * partly also velocity, e.g. by means of radio Doppler shift. ==Bearing-measurement systems== These systems used some form of directional radio antenna to determine the location of a broadcast station on the ground. Conventional navigation techniques are then used to take a radio fix. These were introduced prior to WWI, and remain in use today. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Radio navigation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
