description | To continue positioning a target even if an expiration date of a predicted ephemeris has passed during positioning.SOLUTION: A determination unit 173 determines whether or not a remaining time until an expiration date of a predicted ephemeris, which is prediction data predicting orbit information of GPS satellites, is equal to or less than a determination time set to a time equal to or longer than the maximum time during which the target is expected to be in a certain state. When it is determined that the remaining time until the expiration date of the predicted ephemeris is equal to or less than the determination time, a positioning unit 174 executes an acquisition operation of an actual ephemeris, which is actual orbit information data of the GPS satellites based on GPS signals received by a GPS receiving unit 120, and positions the target based on the actual ephemeris acquired by the execution of the acquisition operation.SELECTED DRAWING: Figure 2
【課題】測位中に予測エフェメリスの有効期限が経過した場合でも、対象を継続して測位する。【解決手段】判別部173は、GPS衛星の軌道情報を予測した予測データである予測エフェメリスの有効期限までの残り時間が、対象がある状態にあると想定される最大時間以上の時間に設定された判定時間以下であるか否かを判別する。測位部174は、予測エフェメリスの有効期限までの残り時間が判定時間以下であると判別されているときにGPS受信部120により受信されたGPS信号に基づく、GPS衛星の実際の軌道情報データである実エフェメリスの取得動作を実行させるとともに、当該取得動作の実行により取得された実エフェメリスに基づいて、対象を測位する。【選択図】図2 |
