It is an object of the present invention to perform positioning at the proper positioning time and positioning precision in response to a requirement with respect to positioning. A positioning server 10 comprises a first positioning component 12 that performs positioning of a cellular terminal 20 by a hybrid algorithm 1, in which indoor/outdoor determination is performed on the basis of reception state information indicating the reception state at the cellular terminal 20, and in which an end condition is determined on the basis of the result of the indoor/outdoor determination; and a second positioning component 13 that performs positioning of the cellular terminal 20 by a hybrid algorithm 2, in which the approximate position of the cellular terminal 20 is calculated on the basis of reception state information indicating the reception state at the cellular terminal 20, and in which whether or not to end the positioning of the cellular terminal 20 is decided on the basis of the precision of the approximated position.
