Summary:Extension of the available data-gathering period has been a subject in wild animal tracking. If the weight of the fitted equipment is less than 200 g, in particular, then reduced power consumption by the GPS receiver is important because a large-capacity battery cannot be carried. The purpose of this study was to extend the period of tracking by estimating an animal moving-pathway based on the measured barometric altitude history between GPS-positioned points. The route is estimated by comparing the pressure-altitude history with a digital elevation model (DEM). As a result, the route over 2 h could be reproduced, based on the barometric pressure history, which was collected on a mountain. In conclusion, this method is expected to triple the available period, compared with the high-frequency GPS positioning method. This should lead to more effective protection of small mammals.
