Abstract

We investigated ways to apply the ICAO standard atmosphere to altitude estimation using the atmospheric pressure sensor in mobile terminal. Two error factors in particular were found to affect estimation accuracy. We tested an estimation method that corrects for the current sea-level pressure and current sea-level temperature by using external weather information. We were able to estimate altitude with an average error of 1-2 m by using highly reliable and accurate atmospheric pressure measured at a distance at long intervals and less reliable atmospheric pressure measured nearby at short intervals.
