Abstract (en)
It is proposed to provide a transponder system for a rail application comprising a first radiation unit forming a first beam that radiates at a first angle with reference to a railway track, a second radiation unit forming a second beam that radiates at a second angle with reference to the railway track, wherein the first angle and the second angle are different. This allows the transponder to determine the position of a rail vehicle with high accuracy, it allows to cancel cross-talk and it allows determining the direction of movement. The transponder system may be used as or within a balise. Also, a method is provided to utilize this transponder in an efficient way.
