Mobile tracking with AT commands, alternative to GPS?
So I know that phone companies can track a phone by the distance between it and it's antennas, I think some phones use this as an alternative to GPS. I started playing with telit GSM modems and was curious if there were AT commands I can use on it that I can pull the signals from different antennas so I can develop my own software to track it. Make sense? By the way I know this isn't dead on accuracy, more like multi football field accuracy but it is fine for my application.
