Hi,
I am interested in the basics of goalref technology however there is not many material out there.
What i want to know is why does the magnetic fields have to be low frequency? and how does it detect if the ball has fully crossed the line? And lastly what is the purpose of the coils within the ball?
Any help to clarify these is appreciated.
Thanks
