Wireless Local Area Network Assisted GPS in Seamless Positioning
Wireless Local Area Network (WLAN) is a new information access platform which can be used to achieve positioning, monitoring and tracking in wide area. Self-positioned of the network node is the basis and prerequisite for most applications,although the current popular WiFi positioning technology is a position solution for WLAN series standard (IEEE802.11). In this paper, based on the principle of satellite navigation and positioning with wireless sensor networks,the new method of combining GPS and WiFi networks is put forward to achieve seamless positioning and navigation. And the potential problems of existed technology are conducted in-depth discussion by summing up the seamlessly, current location and navigation technology, as well as analyzingexisted problems and trends. Finally, the WiFi network assisted GPS positioning algorithm is analyzed in detail.
