I am interested in being able to use GPS to locate people and equipment
inside a -22 freezer that is roughly 100 meters square.

I was reading about a product to bring a GPS signal inside a building:

At the same time I am looking for high accuracy (less than 1 meter) so I
might need to set up a DGPS in addition.

Has anyone had any experience with doing something like this? Please
contact me off-line at davek at cloverleaf dot com
