There are many traveling information on the websites and books, but those information are passive and not immediate. In this paper, we implement a Personal Navigation System (PNS). The PNS provides two kinds of location based services which can immediately produce the information to help people traveling. For location based services, the position information of the user is required. We propose a method to integrate the GPS and IMU by a Kalman filter to calculate the position of user, and make the position be reasonable by some heuristics. This method allows our system can continuously provide high precision position information even though it is short of GPS signal. This position information plays an important role for location-based services.
