Under the rapid development of satellite communication systems and satellite navigation systems, there is an urgent need to combine the two together in order to achieve location-based services, etc. Despite the long relationship history of navigation and communication, the two satellite systems are basically independent of each other. As a result, terminal size tends to be relatively large, and...

The applications of Global Positioning System (GPS) are increasingly widespread in China. GPS positioning is more and more popular. Especially, the automotive navigation system which relies on GPS and Dead Reckoning technology is developing quickly because of the anticipated huge future market in China. In this paper a practical combined positioning model of GPS/DR is put forward. This model de...

For low-cost and continuous indoor navigation, an INS/Wi-Fi (inertial navigation system/Wi-Fi) integrated system is expected to yield a synergetic effect resulting in higher navigation performance than using the standalone systems. In this paper, the authors explore the integration of Wi-Fi measurements with data from microelectromechanical systems based inertial measurement unit for indoor veh...
