Function
As the antenna passes over the Transponder, it energizes the latter with an energy field
of 128 kHz. The transponder transmits its code back at half this frequency.
The relative Transponder position is measured via coils (this relative position does not
provide the knowledge of the heading of the vehicle, as the field of the Transponder is
rotation-symmetric to the longitudinal axis of the Transponder).
The internal interpreter unit decodes the Transponder code and interpolates the Tran-
sponder position rectangular to the direction of travel from the measured values. Each
coordinate axis crossing in direction of travel generates a positioning pulse of adjust-
able duration. In addition, various parameters of the antenna, such as current con-
sumption and power supply voltage are measured and may be added to the serial
output protocol or sent via CAN bus.
