摘要： It is an object of the present invention to perform positioning at favorable positioning precision and in a favorable positioning time, according to whether a receiver is indoors or outdoors. A positioning server 10 comprises a reception state information acquisition component 12 that acquires reception state information indicating the reception state of a radio wave at a cellular terminal 20, a base station positioning calculator 13 that estimates the position of the cellular terminal 20 on the basis of the reception state information, an end decision component 14 that decides whether or not to end the position estimation on the basis of a specific end condition, and, if it is decided not to end, estimates the position of the cellular terminal 20 on the basis of new reception state information, an indoor/outdoor determination component 15 that determines whether the cellular terminal 20 is indoors or outdoors on the basis of the reception state information, and an end condition determination component 16 that determines the specific end condition on the basis of a result of determination by the indoor/outdoor determination component 15.
