摘要

今天的GPS导航仪很难确定高度，比如汽车是在立交桥下还是在立交桥上。在本文中，我们展示了如何使用现成的智能手机自带的气压计来提高垂直定位精度。我们将展示不同真实道路场景的性能测试结果，以展示所提出方法的可行性。

Using Barometer on Smartphones to Improve GPS Navigation Altitude Accuracy

Today's GPS navigators have difficulty determining altitude such as whether a car is under or on an overpass. In this paper, we show how to use the barometers, which come with off-the-shelf smartphones, to improve vertical positioning accuracy. We will present performance testing results from different real road scenarios to show the feasibility of the proposed method.
