To provide a positioning device, a work vehicle, a positioning method, and a positioning program with which, when determining the position of a moving object on the basis of correction information that corresponds to a specific base station, it is possible to prevent the base station from being switched over.SOLUTION: A first positioning processing unit 151 executes stand-alone positioning for calculating the position of a work vehicle 10 on the basis of satellite signals received from satellites. A transmission processing unit 152 transmits stand-alone positioning information to a base station server 20 that selects one base station. An acquisition processing unit 153 acquires correction information that corresponds to the one base station from the base station server 20. A second positioning processing unit 154 executes RTK positioning for calculating the current position of the work vehicle 10 on the basis of the correction information. When RTK positioning of the work vehicle 10 based on first correction information that corresponds to a first base station becomes possible, the transmission processing unit 152 transmits the stand-alone positioning information immediately before RTK positioning becomes possible to the base station server 20.SELECTED DRAWING: Figure 2 【課題】特定の基地局に対応する補正情報に基づいて移動体を測位する場合に、当該基地局の切り替えを防ぐことが可能な測位装置、作業車両、測位方法、及び測位プログラムを提供する。【解決手段】第１測位処理部１５１は、衛星から受信する衛星信号に基づいて作業車両１０の位置を算出する単独測位を実行する。送信処理部１５２は、一の基地局を選択する基地局サーバー２０に単独測位情報を送信する。取得処理部１５３は、前記一の基地局に対応する補正情報を基地局サーバー２０から取得する。第２測位処理部１５４は、前記補正情報に基づいて作業車両１０の現在位置を算出するＲＴＫ測位を実行する。送信処理部１５２は、第１基地局に対応する第１補正情報に基づく作業車両１０のＲＴＫ測位が可能になった場合に、ＲＴＫ測位が可能になる直前の前記単独測位情報を基地局サーバー２０に送信する。【選択図】図２
