Abstract:

To provide a current position output device, a current position output method, and a current position output program which can identify the position of a user accurately even in a stratified area.

A control section 11 periodically performs a standard atmospheric pressure information acquisition request to a base station, acquires standard atmospheric pressure information including atmospheric pressure and the elevation of the base station from the base station, and stores it in a data storage section 15. The control section 11 periodically calculates the elevation of a current position using the measured value of atmospheric pressure acquired from a pressure sensor 16 and an elevation calculation formula including the standard atmospheric pressure information and stores it in the data storage section 15. When an emergency button is pressed down, the control section 11 performs emergency notification including current elevation which is calculated at this time and is stored in the data storage section 15 or elevation which has been already stored in the data storage section 15 to emergency notification.
