GPS World published a great interview with Nemerix CTO Lionel Garin, look up for the next buzzword after LBS.
It goes about his view on Wi-Fi + GPS and promises from Galileo’s precison with this quote:
”No company will develop an application until they have a reasonable view of this.”as in how precise it will actually be.
Look also in the current edition of the magazine for a long “survey” of GPS receivers (of the professional kind, not Geocaching ones. No easily findable link for now.).
