System Description
OUTLINE
The 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 identi®ed 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.
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data
can be used.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
TRAVEL DISTANCE
Travel 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 ®ne
adjustment function has been adopted.
TRAVEL DIRECTION
Change 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 sensor) +
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.

GPS (GLOBAL POSITIONING SYSTEM)
GPS (Global Positioning System) has been developed and con-
trolled by the US Department of Defense. The system utilizes GPS
satellite (NAVSTAR), sending out radio waves while ¯ying on an
orbit around the earth at the height of approx. 21,000 km (13,000
miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-di-
mensional positioning). If radio waves were received only from
three GPS satellites, the GPS receiver calculates the vehicle's
position in two dimensions (latitude/longitude), utilizing the altitude
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 DESCRIPTION
NAVI control unit
+The 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.
DVD-ROM drive
Maps, traffic control regulations, and other pertinent information
can be easily read from the DVD-ROM disc.
Map DVD-ROM
+The 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.

+ Ten horizontal grid lines indicate display width while six vertical
grid lines indicate display depth and direction.
+ Drawing line area shows open space, depth, and immediate
