help on what type of sensor to use

I am trying to make a school project where I have a Bluetooth device that can read my location. I will be attaching a gopro on top of a servo and would like the servo to turn in the direction I am. The main purpose is to have the camera follow me in a 360 deg motion as I walk around it. So my main question is what type of sensor would I use to determine my location.

The sensor you need is a gyroscope.

Most servos will not do 360 degrees. The continuous rotation ones can not be set to a specific angle.
