be picked up from any open area on the
ground’s surface.
The accuracy of the GPS information
depends on how good the reception is.
When the signals are strong and reception
is good, GPS can determine latitude,
longitude and altitude for accurate
positioning in three dimensions. But if
signal quality is poor, only two dimensions,
latitude and longitude, can be obtained
and positioning errors are somewhat
greater.
The built-in sensor in the navigation
system also calculates your position. The
current location is measured by detecting
driving distance with the speed pulse, the
turning direction with the gyro sensor and
inclination of the road with the G sensor.
The built-in sensor can even calculate
changes of altitude, and correct the
discrepancies in the distance travelled
caused by driving along winding roads or
up slopes.
If you use this navigation system with
connecting the speed pulse, the system
will become more accurate than no
connection of speed pulse. So you connect
the speed pulse without fail to get the
accuracy of positioning.
The position of the speed detection
circuit vary depending on the vehicle
model. For details, consult your
authorised Pioneer dealer or an
installation professional.
Some types of vehicles may not output a
speed signal while driving at just a few
kilometres per hour. In such a case, the
current location of your vehicle may not
be displayed correctly while in traffic jam
or in a car park.
For maximum accuracy, your navigation
system continually compares GPS data
with your estimated position as calculated
from the data of built-in sensor. However, if
only the data from the built-in sensor is
available for a long period, positioning
errors are gradually compounded until the
estimated position becomes unreliable. For
this reason, whenever GPS signals are
available, they are matched with the data
of the built-in sensor and used to correct it
for improved accuracy.
If you use chains on your wheels for
winter driving or put on the spare wheel,
errors may suddenly increase because of
difference in wheel diameter. Initialise the
sensor status and it may recover the
accuracy to normal condition (page 129).
Map matching
As mentioned, the positioning systems
used by this navigation system are
susceptible to certain errors. Their
calculations may, on occasion, place you in
a location on the map where no road
exists. In this situation, the processing
system understands that vehicles travel
only on roads, and can correct your
position by adjusting it to a nearby road.
This is called map matching.
Positioning by dead reckoning
How do GPS and dead reckoning
work together?
