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
