About AutoVu satellite hardware
If an AutoVu system needs to provide basic satellite positioning, or if more precise odometry
information is required in order to georeference license plate reads, you must install a satellite
antenna on the Patroller vehicle. The required antenna depends on whether the system includes an
LPR Processing Unit with the AutoVu Navigation Option, an external Navigator box, or an external
USB GPS.
Satellite hardware configurations
Depending on the LPR Processing Unit you are installing and the requirements of the AutoVu system,
the following three satellite hardware configurations are available:
•
LPR Processing Unit with the AutoVu Navigation Option:
If the LPR Processing Unit includes
the AutoVu Navigation option, you can connect the satellite antenna directly to the unit. When
combined with pulse odometry from a Magneto kit or the vehicle's VSS, the AutoVu system
can accurately track the vehicle's route and can georeference license plate reads and track the
vehicle's route..
For more information, see
Installing navigation hardware for LPR Processing units that include
on page 52.
•
LPR Processing Unit with an external Navigator box:
If you are installing an older version of the
LPR Processing Unit, the navigation hardware is not included on the unit. If you require precise
odometry to accurately georeference license plate reads, you must install an external Navigator
box in the vehicle. When combined with pulse odometry from a Magneto kit or the vehicle's VSS,
the AutoVu system can accurately georeference license plate reads and track the vehicle's route.

•
LPR Processing unit with an external USB GPS only:
For Patroller vehicles that do not include
wheel imaging cameras, if a GPS source is not already available in the vehicle, you can install the
basic USB GPS antenna.

About precise odometry
City parking enforcement often requires the use of wheel imaging cameras. The Patroller vehicle
takes photos of parked vehicles' wheels, and multiple passes can determine if the vehicle has moved
even a small distance. Wheel imaging replaces the traditional tire chalking.
How precise odometry is obtained
If you are using an LPR Processing Unit with the AutoVu Navigation option or an external Navigator
box, the hardware comes with a satellite receiver that obtains satellite positioning information. In
addition, the system has an internal gyroscope and receives odometry information from the vehicle
(VSS or magneto). This provides greater reliability than satellite positioning alone. For example, if
you drive through a long tunnel you will lose the satellite signal, but the AutoVu system still knows
how far and how fast you are driving (odometry signal), and if you change direction (gyroscope and
accelerometers).
