Analysis of goal line technology from the perspective of an electromagnetic field based approach

The aim of this work is to analyze Goal Line Technologies with focus on the electromagnetic field based approach GoalRef. This paper will give an overview of the requirements that must be fulfilled by to get approved by FIFA. The existing solution approaches will be described and possible environmental influences like occlusion or deformation of the ball that can affect the system's performance will be discussed. Afterwards, GoalRef will be presented in detail. Finally measurement results for one test scenario in the lab will be presented to validate the system approach and to determine the potential accuracy range of the system.
