To prevent a procedure for readjusting the direction of antenna orientation from being inadvertently activated.SOLUTION: According to an embodiment, a satellite capturing device comprises an antenna for receiving a radio wave from an artificial satellite, as well as a strength calculation unit, a position sensor, a determination unit, an attitude sensor, a search unit and a reexecution control unit. The strength calculation unit calculates the received strength of a radio wave. The position sensor acquires position information at an installation site. The determination unit determines an artificial satellite search range from the installation site on the basis of the acquired position information. The attitude sensor detects the attitude of the antenna at the installation site. The search unit executes an automatic adjustment procedure for adjusting the direction of antenna orientation within the search range on the basis of received strength. The reexecution control unit reexecutes the automatic adjustment procedure when the received strength decreases to or below a prescribed value and a change amount of attitude increases to or above a threshold after the automatic adjustment procedure is completed.SELECTED DRAWING: Figure 3

    【課題】 アンテナ指向方向の再調整手順が不用意に起動してしまうことを防止すること。【解決手段】 実施形態によれば、衛星捕捉装置は、人工衛星からの電波を受信するアンテナ、および、強度算出部と、位置センサと、決定部と、姿勢センサと、探索部と、再実行制御部とを具備する。強度算出部は、電波の受信強度を算出する。位置センサは、設置場所における位置情報を取得する。決定部は、設置場所からの人工衛星の探索範囲を、取得された位置情報に基づいて決定する。姿勢センサは、設置場所におけるアンテナの姿勢を検知する。探索部は、受信強度に基づいて、アンテナの指向方向を探索範囲内で調整するための自動調整手順を実行する。再実行制御部は、自動調整手順が完了した後に、受信強度が規定値以下となり、かつ、姿勢の変化量が閾値以上となった場合に、自動調整手順を再度実行する。【選択図】 図3
