Thanks for reading Cullen.  I was very well aware of that issue in writing this.  

Further reading on how this might be done with GPS is found in draft-thomson-geopriv-grip-gps, including examples.

I've been intending to come back and remove some of its semantic-free-ness as I learned more about how Galileo/GLONASS/etc... express their assistance data.  It might be that patterns emerge that could be exploited.  As yet, I haven't found a pattern, Galileo looks a lot like GPS from their preliminary specs, GLONASS looks very different  (their signals operate in Cartesian coordinate space mostly, they don't provide Keplerian orbit parameters, f'rinstance).
