To provide a position information acquisition device with which it is possible to save on electric power that is consumed in order to acquire position information.SOLUTION: Provided is a position information acquisition device 100 constituted so as to be able to access a storage device 300 in which map information that includes information pertaining to a node 7 and a link 5 is stored. The position information acquisition device 100 comprises: acquisition means 110 for acquiring position information that indicates which position of which link 5 a user terminal 10 exists at at a prescribed point of time, and information that indicates the advance direction of the user terminal 10 at the prescribed point of time; and determination means 120 for referring to the map information and determining, on the basis of the distance from a position on link 5 indicated by the position information to the node 7 the user terminal 10 passes through next after moving along the link 5 in the advance direction, the timing with which the acquisition means 110 acquires the next position information and information that indicates the advance direction.SELECTED DRAWING: Figure 3
【課題】位置情報取得のために消費される電力を節約することが可能な、位置情報取得装置を提供すること。【解決手段】ノード7及びリンク5に係る情報を含む地図情報を記憶している記憶装置300にアクセス可能に構成された位置情報取得装置100において、ユーザ端末10が、所定時点において、どのリンク5のどの位置に存在するかを示す位置情報と、前記所定時点におけるユーザ端末10の進行方向を示す情報とを取得する取得手段110と、地図情報を参照し、位置情報が示すリンク5上の位置から、ユーザ端末10がリンク5上を進行方向へ移動して次に通過するノード7までの距離に基づいて、取得手段110が次に位置情報と進行方向を示す情報とを取得するタイミングを決定する決定手段120と、を備える。【選択図】図3
