Abstract
A location of a mobile unit is intermittently measured based on a GPS satellite signal. A halt start time zone (first halt determination region) is set based on the measured location of the mobile unit when the determination is started. An each time zone (second halt determination region) is updated and set by accumulated averaging processing (statistical processing) of results of location measurements in the past. Whether or not the halt state of the mobile unit is continued is determined using whether or not the newly measured location of the mobile unit is contained in any one of the set halt determination regions.
