Add this to the mix of location technologies that we need to track...

The current issue of CACM (a special issue on the "disappearing
computer"), has an article on PlaceLab [1], which makes the following
assertion about Galileo [2]:

  By 2008 the European Union will deploy Galileo, a next-generation
  GPS system that promises greater accuracy and operation covering
  both indoors and out, due to stronger radio signals that should
  penetrate most buildings.

If true, this could be a significant option for client-side derivation
of location.  Apparently, Galileo is expected to work indoors due to
its use of ultra-wideband (UWB), but I'm over my head in terms of RF
technology.

Any PICers know more about this?
