<P>PROBLEM TO BE SOLVED: To provide an altimeter for surely acquiring a moving operation frequency and moving altitude difference in a vertical direction by performing automatic counting. <P>SOLUTION: In an altitude changing operation composed of a combination of operations including a rise and fall with a predetermined reference altitude difference or more, stored frequency data is made to step forward each time it is determined that a rise with the reference altitude difference has occurred from the lowest altitude measured by altitude measurement means in each case of the fall of the altitude changing operation, a period of the altitude changing operation corresponding to the previous rise with the reference altitude difference is determined, and a moving vertical altitude is calculated based on the altitude difference in the period of the altitude changing operation and integrated in cumulative vertical altitude data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
