The popularization of smartphone and continuous upgrading of configuration make the 4A target (anytime, anywhere, anybody and anything) for location service become possible. Pedestrian navigation based on smartphone is an ideal solution for indoor and outdoor seamless positioning. Mobile navigation electronic map is the basis of pedestrian navigation. A smartphone seamless positioning system based on outdoor and indoor mobile navigation electronic map is proposed in this paper. Indoor map adding seamless connection between indoor and outdoor geographic information, which is convenient for initial position determination and heading constraint. The inertial sensors and GNSS module are combined to complete the navigation solution, and the navigation software is designed in eclipse environment. The Baidu map software package is used to carry on the secondary development to support the solution and display. The experiment verified the feasibility of the smartphone seamless positioning system, which can real time display the navigation solution and work dead zone free.
