Abstract

Techniques are described for position source selection. In an implementation, an electronic device provides a variety of functionality including at least functionality to determine position. The electronic device may be further configured to select between a plurality of position sources to determine position based upon a variety of selection criteria. In an implementation, a last known position may be stored when position is being determined through the plurality of position sources. The last known position may be used as an alternative to determining position via the position sources when one or more of the position sources are unavailable. In another implementation, the last known position may be employed to automatically select one of the plurality of position sources to be used by the electronic device for determining position.
