I would love to hear more about this technology that you are talking about. 
When I worked at AT&T Wireless and Ericsson, we tested many positioning 
technologies. If you are talking about time alignment factor both on GSM and 
TDMA, and even with neighboring cell information, and even combine it with 
smart array antenna technology, I doubt if you can get close to 15 meter 
accuracy. Given the moving vehicle speed or even walking speed, I`m curious 
to learn about how the technology can get to 1 m precision. So please share 
with me about the technology you are talking about.

Thanks,

Punnamas
