That's exactly how it works:
> When the cellular phone detects that the user is placing an emergency call, it begins to transmit its location to a secure server, from which the [Public Safety Answering Point] can retrieve it. Cellphone manufacturers may program the phone to automatically enable GPS functionality (if disabled) when an emergency call is placed, so that it may transmit its location.
