Emergency Mode and GPS activation

[Ziiar]

Just got a Galaxy S3 and plan on keeping GPS off unless I need it. If I dial 911, putting the phone into emergency mode, will the GPS active itself automatically so emergency services can track the phone?

Also, my previous phone had GPS but I had no data plan or anything and never activated it. If I had dialed 911 would the GPS active?

I'm almost positive they can track the phone even with gps off.

My old phone used to say something along the lines of hiding location from all except emergency services when you had the gps off
