Introduction
The described antenna is designed to be used for positioning and/or trackguiding ve-
hicles in rough outdoor environment, as all electronic components are fully sealed as
well as equipped with an extended temperature range. All important parameter set-
tings, calibration and updates are carried out via an integrated serial interface.

Examples of automated vehicles using transponder systems
Antenna HG 98860ZA utilizes a completely new antenna concept, which has a large
reading area with a linear transponder positioning function. The antenna is so-called
2-dimensional, meaning that it outputs the Transponder code as well as the linear de-
viation rectangular to the direction of travel, in direction of travel and in addition the
information “Crossing of the transponder“.
NOTE!
The accuracy of the measured value for the position X (in direc-
tion of travel) only meets the specified accuracy (see Table 14 on
page 48) for travelling speeds of up to 1 m/s! For higher speeds
the positioning pulse has to be used as the reference which has
an accuracy within the millimeter range.
NOTE!
The point at which the positioning pulse is generated is not
exactly the same point at which the position X is equal to zero (X
= 0) since these points are calculated using different procedures.
For the above described antenna, the use of Transponders of the type HG 70653ZA
(Read Write — RW) is mandatory.
The transponder antenna has an output format, which enables the user to configure
additional system information. This additional information, for example, may be used
by an external visualization system (e.g. vehicle control unit with display) and enables
statements regarding the condition and availability of antennas and transponders.
This system description refers to Transponder Positioning Antenna HG 98860ZA with
the firmware 98860MA1.0 or higher (also refer to Figure 17 on page 33).
