2-dim. Positioning and Identification Antenna
HG G-98830 / HG G-98835
with CAN / CANopen® or PROFINET®
The transponder antenna is used to localize and track automated guided vehicles (AGVs) or cranes with the help of ground markers (transponders). All settings, calibrations or software updates that are important for operation can be carried out via a serial interface or CAN/CANopen®.

Functional Description
As soon as a transponder is in the antenna’s reading range, it is supplied with energy without contact and then transmits its code back to the antenna cyclically every eight milliseconds at half the antenna transmission frequency. The transponder is otherwise completely passive and does not require its own power supply or battery. Only one transponder may be in the reading range of the antenna at any one time.
The position of the transponder relative to the center of the antenna is also determined every eight milliseconds from the signal sent by the transponder to the antenna. The field of the transponder is rotationally symmetrical, so that the orientation or position cannot be determined with a single measurement. The orientation must be determined from a sequence of transponder readings or by means of a second antenna. With a second antenna on the vehicle, it is also possible to determine the orientation when stationary and to navigate omnidirectional vehicles.
The interpreter for determining the code and position is integrated in the antenna. When crossing the Y-axis (transverse to the direction of travel), a high-precision positioning pulse (PosiPulse) with an adjustable duration is emitted. The PosiPulse is available both as a digital output and via the telegrams of the serial and bus interfaces.
