> Some months ago there was a thread on jamming cell phones. Now I am wondering how to get the spatial coordinates of a given cell phone. Is it technically feasible to identify a single cell phone from a satellite or other high point? > The short answer is yes the maths are fairly well established, multiple satellites are better, for either you have to add a great number of qualifiers (which equates to unlimited amounts of money) > Maybe you can guess what I'm wondering. > No, I don't speculate on non-engineering matters if sufficient negotiable currency is put in my bank account. 8-) Regards Chris Carr P.S.
