Anyone doing that is simply wasting their time and your money. A functional Galileo system is at least 8-10 years away away, even assuming they sort out the political and financial deadlock they find themselves in currently. Galileo was a political statement from day one and it has turned out to be an economic non-starter like many predicted. While it would be nice to have an alternative system, don't hold your breath. JMHO opinion, of course.
