Fault tracing for Sensus Navigation
The following are examples of things that may be
interpreted as navigation system faults.
The position of the car on the map is
wrong
The Navigation system shows the position of the
car to an accuracy of about 20 metres.
There is a greater chance of error when driving
on roads lying parallel to another road, on wind-
ing roads, on roads on several levels and after
driving a long distance without making any dis-
tinctive turns.
High mountains, buildings, tunnels, viaducts,
over/underpasses etc. also have a negative
effect on the reception of satellite signals, which
means that accuracy in calculating the position of
the car may decrease.
The system does not always calculate
the fastest/shortest route
When calculating a route, several factors are
taken into account to determine the theoretically
best solution. Factors include route distance, road
width, road classification, traffic intensity and
speed limits. However, an experienced driver with
local knowledge can quite possibly select a bet-
ter route.
