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).
