The model is set by Symeo by delivery.
3.3.1 Hover-Track
The HoverTrack model is used for vehicles that can move in x- and y-direction but cannot
turn over its center. A typical example is the trolley of a crane. The name based on a
hovercraft which can move forward and backward as well as sideward.
To make a 2D-positioning the mobile unit needs at least one antenna. The usage of a
second, third or fourth antenna results in more robust and more reliable position.

3.3.2 Vehicle-Track
If the object can also turn around its center the vehicle-track model is used. Examples for the
vehicle model are each kind of steerable vehicles (fork lift, van carrier, automobile, etc.). It is
possible to determine besides the 2D position also the orientation of the vehicle. For this it is
at least a second antenna necessary.
