Sensus Navigation uses the Global Position-
(p. 32)
ing System (GPS), which indicates the vehi-
cle's position with an accuracy of about
65 feet (20 meters).
Accuracy may be even less when driving on
roads lying parallel to another road, winding
roads, roads on several levels, and also after
driving a long distance without making any
distinct turns.
Tall buildings and mountains, tunnels, via-
ducts, over/underpasses etc., also have a
negative affect on the reception of GPS sig-
nals, which means that the estimation of the
vehicle's position may not be precise.
The system does not always calculate
the fastest/shortest route
Parameters such as distance, width of road,
type of road, number of right or left turns,
traffic circles etc., are all taken into account
when calculating the best theoretical route.
Experience and local knowledge may, how-
ever, lead to a better choice of route.
The system chooses toll roads,
freeways, and ferries even though I
have opted to avoid them
When calculating routes over longer dis-
tances, for technical reasons the system can
only use major roads.
If you opt to avoid for toll roads and freeways,
they will be avoided as much as possible, but
will be used if no other reasonable alternative
is available.
After being transported, the vehicle's
position on the map is incorrect
If the vehicle is transported, for example by
ferry or train, or in such a way as to impede
the reception of GPS signals, it can take up to
5 minutes to calculate the car's new position
correctly.
The vehicle's position on the map is
incorrect after its battery has been
disconnected
If power has been cut from the GPS antenna,
it can take more than 5 minutes for the GPS
signals to be received correctly and the vehi-
cle's position to be calculated.
The "car" symbol on the map moves
erratically after a tire change
In addition to the GPS receiver, the vehicle's
speedometer and an onboard gyro are also
used to calculate the vehicle's current loca-
tion and direction of travel. If the spare tire is
