Claims (1)
を有する磁気検出装置と、該磁気検出装置で得ら
れた方位データが地磁気のみに起因して得られた
信頼し得るデータなのか又は付近に存在する地磁
気以外の磁気源の影響をうけて信頼できないデー
タなのかを判別する方位正誤判別手段とを備えた
ことを特徴とする電子方位計。 A magnetic detection device having a plurality of magnetic sensors arranged at an appropriate distance, and whether the azimuth data obtained by the magnetic detection device is reliable data obtained only from the earth's magnetism, or if it exists nearby. An electronic direction meter characterized by comprising a direction correct/incorrect determination means for determining whether the data is unreliable due to the influence of a magnetic source other than earth's magnetism.
