Abstract
The present invention intends to provide an altitude detecting unit capable of, while utilizing both the advantages of a satellite positioning system and a pressure sensor, making an altitude measurement error, which may occur when combining them, as small as possible, and provide the others, and has determined a conversion expression adapted to convert from pressure into altitude such that at each of multiple valid altitude measurement points at which a satellite positioning system detects accurate altitude, altitude based on pressure is made equal to altitude by the satellite positioning system.
