ln this paper, a practical method for improving GPS– PPP(Global Positioning System–Precise Point Positioning) accuracy in urban canyons are presented by using a barometric pressure sensor. Several techniques to improve PPP quality are also integrated into a PPP algorithm which is available in case that there are few (only two or three) visible satellites from automobiles moving on the street in urban canyons. Therefore, this paper verifies the usefulness to integrate barometric pressure information into these methods.
