Doing some research for a project I am collaborating on with Jeremy Hight, I just learned about DARPA's X-Ray Pulsar-based Navigation and Timing (XNAV) project, a likely candidate for future space navigation beyond the GPS/Galileo web. Seems the whole Solar System will become a location aware arena in the not too far future...
For a good intro, have a look at this DARPA project powerpoint. Some more information can be found at NewScientist (Sep. '06), and The Space Review (Dec. '06).
