Ubisense 3D real time tracking systems require just this kind of 
exercise to calibrate the network of transceivers and tags.

Every space is defined with each device precisely located with fixed 
origin x, y, z coordinates.

I built a demo that could track a tag to within a half meter. This 
ultra-wide band based system uses time difference of arrival and angle 
of arrival to determine location.  www.ubisense.net
