As explained in http://www.locatacorp.com/docs/Locata Primer
v1.3,%20public%20rel,%20Feb 05.pdf (see page 17 onwards) and the
podcast you just use a plain old gps, unlike for DGPS and RTK-GPS.

Their idea is that a museum (say) would buy these locata things and
place them throughout their building then people could wander around
with their smart phone and get information relevant to where they are,
or alternatively firefighters could place the beacons around a burning
building and then be able to record where every firefighter is in
real-time with meter level accuracy.

The technology looks very cool to me.
