To provide a tractor which can receive positioning data transmitted from a GPS satellite or the like and satisfactorily recognize its own position.SOLUTION: The tractor includes a traveling body 4 and a plurality of antenna units 32 provided on the traveling body 4 for receiving satellite positioning data. The tractor identifies its own position based on the data received by the plurality of antenna units 32. Since the positioning data are slightly different from each other in correspondence to the plurality of antenna units, it is possible to improve accuracy of the positioning data, for example, by taking into account the error included in the plurality of the positioning data, or by acquiring an average value.SELECTED DRAWING: Figure 14

    【課題】GPS衛星等から送信される衛星測位情報を受信して自車位置を良好に取得できるトラクタを構成する。【解決手段】走行車体4と、走行車体4に備えられ衛星測位情報を受信する複数のアンテナユニット32とを備え、複数のアンテナユニット32からの受信情報に基づいて自車位置を特定する。複数のアンテナユニットに対応して僅かに異なる位置情報となるため、例えば、複数の位置情報に含まれる誤差を考慮する処理や、平均値を取得する処理等により位置情報の精度の向上が可能となる。【選択図】図14
