A radio communication terminal is used in a position specifying system, in which both retrieval timing and retrieval time of each of GPS satellites are received via a communication base station from a position information server. The position information server specifies a position of the radio communication terminal based upon at least GPS satellite information received from the radio communication terminal. The radio communication terminal corrects at least any one of both retrieval timing and retrieval time so that the retrieval timing is moved, or the retrieval time is prolonged. The radio communication terminal retrieves the GPS satellites based upon the corrected retrieval timing and the corrected retrieval time.
