Abstract
Apparatus and method for positioning a wireless device. In one embodiment, a method for indoor positioning includes determining a reference location of a wireless device, based on satellite positioning, as the device passes between areas of satellite positioning signal reception and satellite positioning signal non-reception. While in the areas of non-reception, signals transmitted by wireless local area network (WLAN) access points (APs) and parameters of motion of the device are measured. Positions of the device are estimated while in the areas of non-reception based on the reference location and the parameters of motion. A positioning grid for positioning is generated based on the signals measured by the wireless device at the estimated positions.
