Aaaaha, I seen it being used for all sorts of archeology and buildings
And from the info in the uBlox-paper, regarding the protocol options it
doesn't seem to me like there is much chance for better precision by the way
they do A-GPS.
Better precision would mean info on meteorological interference (like exact
amount clouds on the way to sat) at the very location of the receiver. To get
this, you need... a reference receiver, so we are at D-GPS again.
