Antenna tracker direction?

Do I have to interactively rotate/tilt the antenna to in the direction of the GPS module or should the antenna automatically turn itself towards the module according to how its programmed? Otherwise, I assume that a GPS script should return the coordinates of the vehicle and it should notify the user where to point the antenna.

I’m using the GPS library from this website: https://randomnerdtutorials.com/guide-to-neo-6m-gps-module-with-arduino/

are you using the ArduPilot AntennaTracker build? http://ardupilot.org/antennatracker/index.html#home
