Claim 10:
11. An information processing apparatus for specifying a position of a terminal apparatus for mobile communication, comprising:
an information receiving section for receiving position information on a radio relay apparatus obtained based on the GNSS signals received by the GNSS reception apparatus, from a radio relay apparatus, with respect to a flight time period during which the radio relay apparatus flies in an upper airspace above a target area on a ground, the radio relay apparatus comprising a directional antenna with directivity in a direction toward the ground, a GNSS reception apparatus for receiving GNSS signals from artificial satellites and a communication apparatus for communicating with the information processing apparatus, and receiving reception measurement information including a measurement result of a reception power or a reception quality from the terminal apparatus that measures the reception power or the reception quality of radio waves transmitted toward the ground from the directional antenna of the radio relay apparatus; and,
a position estimating section for estimating the position on the terminal apparatus in the target area based on the position information on the radio relay apparatus and the reception measurement information.
