The internal interpreter unit decodes the Transponder code and interpolates the Tran-
sponder position rectangular to the direction of travel and in direction of travel from the
measured values.
Each coordinate axis crossing in direction of travel generates a positioning pulse of
adjustable duration.
In addition, various parameters of the antenna, such as current consumption and pow-
er supply voltage are measured and may be added to the serial output protocol.

Application Example
Figure 3
Track guiding a vehicle with one antenna
The figure shows a vehicle with an antenna frame for track guidance.
With the aid of the transponder (T 105) the deviation from the predeter-
mined track is determined. With this information, an external computer is
able to determine the new direction required to return to the predeter-
mined track as soon as possible (the external computer is not part of the
system). Rotary encoders enable changing the direction of travel when-
ever necessary. Thus it is possible to switch tracks at predetermined
points. Again, the vehicle corrects its position independently upon
reaching the next transponder.
