Abstract
An object of the present invention is to provide an altitude measurement system and an altitude measurement method capable of measuring an altitude of a moving body in a stand-alone mode. In order to achieve the present object, the invention provides an altitude measurement system having altitude measurement terminals M1 to Mn connected to the Internet connection and atmospheric-pressure trend management unit TM1 connected to the Internet connection, each of the altitude measurement terminals M1 to Mn including: an atmospheric-pressure measurement unit 201 that measures an atmospheric pressure; a same-floor-stay detection unit 202 and an in-area-stay detection unit 203 for detecting existence of the moving body at a predetermined altitude; and an atmospheric-pressure trend candidate value output unit 204 that outputs, to the atmospheric-pressure trend management unit TM1, atmospheric pressure data measured during a predetermined period by the atmospheric-pressure measurement unit 201 when the existence of the moving body exists at a predetermined altitude, and an atmospheric-pressure trend integration/generation unit 205 generating the reference atmospheric pressure data corresponding to the altitude by, as needed, calculating an average value among a plurality of pieces of the atmospheric pressure data supplied from the atmospheric-pressure trend candidate value output unit 204.
