If desired the master transponder can store the coordinates of the cell (mode 3b). The
master transponder then repeatedly broadcasts his coordinates and all base-stations in
range receive the data. Alternatively the coordinates can be kept on the mobile unit
permanently as in mode 1 (mode 3a).

1: Mobile units
2: fixed mounted units
3: Master unit
4: Communication channel (commands)
5: Broadband measurement signals
Additionally to the described solution of a fixed master, there is the
possibility to use a moving master. In this case each fixed mounted unit
can be the master. The sequence is set by the user.
3.3 Vehicle Model
To determine a 2D-position with an LPR-2DB system a Kalmar filter is used. Therefore a
system model is necessary which represents the system. Depending on the vehicle type in
your application different models can be used:
Hover-Track-Model
Vehicle-Track-Model
Depending on the chosen model for the Kalman filter different numbers of states are
estimated (position, velocity, acceleration, angle, etc).
