Harris Stingers, for starters. But yes, triangulation using the Setup Channel pings + Satellite GPS, handoff information + GPS to identify any movement (will give location, direction and speed), etc.

If you are using technology, "they" can get to you. If you are near technology that is not even yours, they can get to you.

Small Edit: My mind was nagging me that "Stingers" is not correct. The product, which Harris denied for many years, is called a "StingRay". It is a fake "cell site" (mobile telephony base station) that LEOs and probably military and spies use to spoof people's phones.
