SEL504X
System DescriptionNJEL0516OUTLINENJEL0516S01The Navigation System (Multi-AV System) relies upon three sens-
ing devices in order to determine vehicle location at regular time
intervals.
1. Vehicle speed sensor: Determines the distance the vehicle has
traveled.
2. Gyro (Angular velocity sensor): Determines vehicle steering
angle and directional change.
3. GPS antenna (GPS data): Determines vehicle forward move-
ment and direction.
The data provided by the three sensing functions together with a
comparison of the mapping information read from the CD-ROM
drive permit accurate determination of the vehicle's current location
and subsequent course (map matching). The information appears
on a liquid crystal display.
This comparison of GPS data (vehicle position sensing) and map
matching permits precise determination of vehicle location.
SEL684V
Position Sensor Operating PrinciplesNJEL0516S0101The sensor determines current vehicle location by calculating the
previously sensed position, the distance traveled from this position,
and the directional changes occurring during this travel.
1. Distance traveled
The distance traveled is calculated using signals received from
the vehicle speed sensor. The sensor automatically compen-
sates for the slightly reduced wheel and tire diameter resulting
from tire wear.
2. Forward movement (Direction)
Changes in the direction of forward movement are calculated
by the gyro (angular velocity sensor) and the GPS antenna
(GPS data). Each of these functions has its advantage and
disadvantages. Depending upon conditions, one function takes
precedence over the other to accurately determine the direc-
tion of forward movement.
Function type Advantage Disadvantage
Gyro (Angular
velocity sen-
sor)+Able to accurately detect
minute changes in steering
angle and direction.+Calculation errors may
accumulate over a long
period of continuous
vehicle travel.
GPS antenna
(GPS data)+Able to sense vehicle travel
in four general directions
(North, South, East, and
West)+Unable to detect direction
of vehicle travel at low
vehicle speeds.
NAVIGATION SYSTEM
System Description
EL-261

for example, when the vehicle is in a tunnel, in a parking lot
inside building, under an elevated superhighway or near strong
power lines, the location may not be detected. Turbulent/
electric weather conditions may also affect positioning perfor-
mance. If something is placed on the antenna, the radio wave
from GPS satellites may not be received.

COMPONENT DESCRIPTIONNJEL0516S02NAVI Control UnitNJEL0516S0201+The gyro (angular speed sensor) and the CD-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 CD-ROM map.
Locational information is shown on liquid crystal display panel.
SEL506X
CD-ROM DriverNJEL0516S0202Maps, traffic control regulations, and other pertinent information
can be easily red from the CD-ROM disc.
Map CD-ROMNJEL0516S0203+The map CD-ROM has maps, traffic control regulations, and
other pertinent information.
+To improve CD-ROM map matching and route determination
functions, the CD-ROM uses an exclusive Nissan format.
Therefore, the use of a CD-ROM provided by other manufac-
turers cannot be used.
SEL690V
Gyro (Angular Speed Sensor)NJEL0516S0204+The oscillator gyro sensor is used to detect changes in vehicle
steering angle.
+The oscillator gyro periodically senses oscillatory variation at
the oscillation terminals. This variation is caused by changes
in the vehicle angular velocity. Voltage variations are sensed
by ceramic voltage sensors at the left and right sides of the
terminals. Vehicle angular velocity corresponds directly with
these changes in voltage.
+The gyro is built into the navigation (NAVI) control unit.

+Ten horizontal grid lines indicate display width while six verti-
cal grid lines indicate display depth and direction.
+Drawing line area shows open space, depth, and immediate
front area. Each area is to a scale of approximately 5:6:25.

scale change and the view point height on the left side of the
screen.
The height of the view point increases or decreases when
ªZOOMº or ªWIDEº is selected with the joystick.
