Abstract

In this paper, practical methods for improving GPS-PPP (Global Positioning System–Precise Point Positioning) accuracy in urban canyons are presented and examined in real severe circumstances. In our previous work, the method for improving positioning accuracy is presented by using a barometric pressure sensor. And the usefulness of the method was shown by the experiments such that the number of satellites used in the position calculation was artificially decreased to 3. In this paper, the algorithm proposed in our previous work is tested for the automobile which runs in real severe circumstances such as near the skyscrapers, raised expressways and the feasibility and usefulness of the proposed method with few satellites are shown.
