ALTITUDE MEASUREMENT SYSTEM, ALTITUDE MEASUREMENT METHOD, ALTITUDE MEASUREMENT PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To reduce an error caused by weather by providing in real time the atmospheric pressure information on the land surface of a current position to a flying object.;SOLUTION: An altitude measurement system 1 includes: a plurality of second barometer devices 2 decentrally disposed on the land surface and transmitting atmospheric pressure data including information for specifying a measured atmospheric pressure and an atmospheric pressure measuring position at a predetermined interval; a second atmospheric pressure data acquiring portion 32 receiving the atmospheric pressure data from the second barometer devices; a flight data calculation portion 33 calculating flight data including positional data on the flying object; a reference atmospheric pressure calculation portion 34 specifying the atmospheric pressure measuring position based on the atmospheric data received from the second barometer devices, and repeatedly calculating a reference atmospheric pressure of the flying object based on the atmospheric pressure measuring position, an atmospheric pressure measured by the second barometer devices, and the positional data of the flying object at a specific interval; a first barometer device 90 measuring an atmospheric pressure around the flying object; and an altitude calculation portion 36 calculating the altitude of the flying object based on the atmospheric pressure around the flying object and the reference atmospheric pressure.;COPYRIGHT: (C)2013,JPO&INPIT
