1. A method comprising:
- obtaining position fix information from at least a satellite positioning system (SPS) signal;
updating said position fix information based at least in part on a signal metric associated with one or more non-SPS sources;
obtaining a subsequent position fix from an SPS signal using said updated position fix information; and
selecting one or more of a plurality of localization procedures to perform said updating said position fix information based at least in part on one or more criteria.
