SKIA0370E
System DescriptionNJEL0592The navigation system periodically calculates the vehicle’s current
position according to the following three signals: Travel distance of
the vehicle as determined by the vehicle speed sensor, turning
angle of the vehicle as determined by the gyroscope (angular
velocity sensor), and the direction of vehicle travel as determined
by the GPS antenna (GPS information).
The current position of the vehicle is then identified by comparing
the calculated vehicle position with map data read from the map
DVD-ROM, which is stored in the DVD-ROM drive (map-matching),
and indicated on the screen with a current-location mark.
SEL684V
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data
canbeused.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
TRAVEL DISTANCENJEL0592S01Travel distance calculations are based on the vehicle speed sen-
sor input signal. Therefore, the calculation may become incorrect
as the tires wear down. To prevent this, an automatic distance fine
adjustment function has been adopted.
TRAVEL DIRECTIONNJEL0592S02Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). As the gyroscope and GPS antenna have both merit
and demerit, input signals from them are prioritized in each situa-
tion. However, this order of priority may change in accordance with
more detailed travel conditions so that the travel direction is
detected more accurately.
Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor)Can detect the vehicle’s turning angle
quite accurately.Direction errors may accumulate when the
vehicle is driven for long distances without
stopping.
GPS antenna (GPS information)Can detect the vehicle’s travel direction
(North/South/East/West).Correct direction cannot be detected when
the vehicle speed is low.
SEL685V
MAP-MATCHINGNJEL0592S03Map-matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This
is done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map DVD-ROM stored
in the DVD-ROM drive.
Therefore, the vehicle position may not be corrected after the
vehicle is driven over a certain distance or time in which GPS
information is hard to receive. In this case, the current-location
mark on the display must be corrected manually.

data calculated previously by using radio waves from four or more
GPS satellites (two-dimensional positioning).
Accuracy of the GPS will deteriorate under the following conditions.
In two-dimensional positioning, the GPS accuracy will deterio-
rate when the altitude of the vehicle position changes.
There may be an error of approximately 10 m (30 ft.) in posi-
tion detected by three-dimensional positioning, which is more
accurate than two-dimensional positioning. The accuracy can
be even lower depending on the arrangement of the GPS sat-
ellites utilized for the positioning.
Position detection is not possible when the vehicle is in an area
where radio waves from the GPS satellite do not reach, such
as in a tunnel, parking lot in a building, and under an elevated
highway. Radio waves from the GPS satellites may not be
received when some object is located over the GPS antenna.
Position correction by GPS is not available while the vehicle is
stopped.

COMPONENT DESCRIPTIONNJEL0592S05AV and NAVI Control UnitNJEL0592S0501The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.
Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Locational information is shown on liquid crystal display panel.
PKIA0249E
DVD-ROM DriveNJEL0592S0502Maps, traffic control regulations, and other pertinent information
can be easily read from the DVD-ROM disc.
Map DVD-ROMNJEL0592S0503The map DVD-ROM has maps, traffic control regulations, and
other pertinent information.
To improve DVD-ROM map matching and route determination
functions, the DVD-ROM uses an exclusive Nissan format.
Therefore, the use of a DVD-ROM provided by other manufac-
turers cannot be used.
Gyro (Angular Speed Sensor)NJEL0592S0504The oscillator gyro sensor is used to detect changes in vehicle
steering angle.
The gyro is built into the navigation (AV and NAVI) control unit.
