摘要： In one embodiment, the position of a mobile device is determined based, at least on part, of the relative locations of two or more nearby points. Distance data, received from a range finding sensor, corresponds to distances to the two or more nearby points from the mobile device. A predetermined model that includes previously recorded locations for objects is accessed to receive location data for two or more nearby points. A position of the mobile device is calculated based on the location data and the distance data. The nearby points may be building edges or building corners. The calculation may involve a series of equations. The series of equations may include satellite-based positioning equations in addition to equations based on the predetermined model.
