摘要： The present disclosure provides a method for determining a real-time position of a mobile device using a global positioning system (GPS) and wireless local area network (WLAN) hybrid positioning mode. The method includes determining, by a mobile device, the mobile devices environment area based on GPS satellite signals; determining an absolute position of the mobile device based on the GPS satellite signals while the mobile device is moving from an outdoor area to an indoor area; estimating a reference position of the mobile device based on the determined absolute position and WLAN access point signals while moving to a shadow area; and while moving to an indoor area, determining an estimated position of the mobile device based on calculated regressive coefficients and the WLAN access point signals, and updating the estimated position of the mobile device based on motion information and indoor floor map information.
