Abstract

Various techniques are provided which may be implemented as methods, apparatuses and articles of manufacture for use by a mobile device or one or more computing devices to provide for or otherwise support motion state based mobile device positioning. In an example, a method may be implemented at a mobile device to identify two or more subsets of grid points corresponding to an electronic map representing a particular environment, select one of the two or more subsets of grid points for use in position estimation based, at least in part, on a motion state of the mobile device, and determine an estimated position of the mobile device based, at least in part, on the selected subset of grid points.
