The digital radio format adopted for NAS vehicles is satellite radio. Satellite service providers transmit a signal from their
up-link facility (which is the original point of transmission of data, voice or other information through an antenna system) to a
satellite where the signal is then down linked to both the terrestrial repeater network and the individual satellite car radios.
The radio switches between the satellite signal and the repeater network signal depending on the strength of the signal at any
given time.
The Sirius satellite system comprises:
Satellites
Ground repeaters
Up-link ground stations
Radio receiver systems

The Sirius satellite radio system uses three satellites on an inclined elliptical orbit. This ensures that each satellite spends
approximately 16 hours a day over the continent of the USA, with at least one satellite over the country at any one time.

The satellites beam their signals down to the ground where the signal is picked up by receivers or is transmitted to repeater
stations to cover built up areas where the signal is obscured. The satellite service comprises over 100 channels of digital
entertainment which is provided by subscription requiring a monthly payment.

Operation of the satellite radio system is the same as the radio operations with selections made through the Touch-screen and
ICP to access and navigate the system functions.

The satellite radio receiver is a dedicated tuner which is controlled by the ICM on the MOST ring. The receiver filters the
signals from the satellite radio antenna. Information is transmitted on the MOST ring and processed by the ICM. The processed
information is sent out to the power amplifier or IAM (with internal amplifier) and broadcast through the speaker system.

No configuration procedure is required if the satellite radio receiver is replaced. Calibration of the satellite radio receiver using
the Jaguar approved diagnostic equipment enables updates to be downloaded as new technology becomes available or any
fault concerns require software updates.
Satellite Radio Antenna



The satellite radio antenna is located in the roof pod and is shared with the navigation system GPS (global positioning system)
antenna where fitted. The roof pod is located externally in a central position towards the rear of the roof.

Similar to the DAB system the satellite radio antenna is designed with 50 ohm output impedance. The satellite radio receiver
is fitted with 50 ohm fakra II connectors to ensure compatibility with the antenna. For optimum performance 50 ohm low loss
coaxial cable is used between the antenna and receiver.

The antenna is designed to receive one of two signals, using the strongest signal with the least distortion to process for audio
output. For example, if the vehicle drives into a tunnel, the signal received will change from a satellite signal to a repeater
station signal maintaining the strongest signal. SATELLITE RADIO (NAS VEHICLES ONLY)

Description and Operation

OVERVIEW

The navigation system provides audible and visual route guidance information to enable the driver to reach a desired
destination. The system allows the driver to choose the desired route using minor or major roads and will present 3 routes to
the driver based on user preferences. Directions to hospitals, museums, monuments and hotels are also available. The
navigation computer uses map information stored on a DVD (digital versatile disc) to determine the best route for the journey
and provide the driver with details of directions and approaching junctions.

The navigation system has various levels of user control through the Touch-screen and JaguarVoice system. System volume
adjustment can be made using the ICP (integrated control panel), Touch-screen and steering wheel controls.

There are 3 navigation system variants specific to various markets. On all systems the GPS (global positioning system) signal
is received by the GPS (global positioning system) antenna located in the roof pod antenna module.

The European navigation system includes the TMC (traffic messaging channel) function, which receives traffic information from
an FM antenna integrated into the heated rear window. On a pre-selected route the system will offer re-routing options
depending on traffic conditions.

The Japanese navigation system includes the VICS (vehicle information and communication systems) function. The VICS
(vehicle information and communication systems) supplies information to enable the navigation computer to re-route the
navigation guidance or to inform the vehicle driver of traffic conditions in the vehicles vicinity. Information is provided to the
system through an FM antenna integrated into the heated rear window and a VICS beacon located in the LH upper side of the
instrument panel.
The NAS (North American specification) variant does not include any additional traffic information systems.

The navigation system is primarily controlled from the Touch-screen which is located in the center of the instrument panel.
Control signals from the Touch-screen are sent on the MOST (media oriented systems transport) ring to the navigation
computer. The navigation computer uses a dedicated GVIF (gigabit video interface) bus to transmit video signals to the Touch-
screen.

Depending upon the audio system version fitted the navigation audio output signals are sent on the MOST (media oriented
systems transport) ring to the IAM (integrated audio module) or the power amplifier for speaker output.

Authoring Template System Operation

INTRODUCTION TO THE GLOBAL POSITIONING SYSTEM

The system used to calculate the current position of the vehicle is called the GPS. The system utilizes satellites which are owned by the United States Department of Defense. A total of 24 satellites circular orbit the earth every 12 hours at a height
of 20,000 km (12500 miles), and between 5 and 11 of these satellites can be seen from a single point at any given time. The
orbits are tilted to the earth's equator by 55 degrees to ensure coverage of polar regions. Each satellite transmits radio signals
to provide information about the satellite position i.e. latitude, longitude, altitude, almanac data and an accurate time signal
generated by an on-board atomic clock. Each satellite contains four atomic clocks.
The vehicle needs to receive data from at least four different satellites to give a three dimensional fix on its current position.

As the vehicle moves, this information is continually being updated. The computer determines which satellites are 'visible' to
the system and their current position and relationship to each other. Using this information the computer can account for
positional deviations of the satellites and compensate to enhance the accuracy of the navigation system.

VICS (vehicle information and communication system) receiver (Japan only)
TMC (traffic message channel) receiver (Europe only)
JaguarVoice control module

The navigation computer contains a solid state piezo gyro which measures the motion of the vehicle around its vertical axis.
The gyro operates on the principle known as the coriolis force. The coriolis force is the force that appears to accelerate a body
moving away from its rotational axis against the direction of rotation of the axis.

Using inputs from the ABS module, the GPS antenna and the gyro sensor, the computer calculates the vehicle's current position, direction and speed.

The navigation computer houses the DVD (digital versatile disc) drive. The drive is used to read map data from region specific
DVD's. The number of DVD's issued per region varies depending on the amount of information available. The regions are as follows:

Europe (2 versions, Western Europe and Whole of Europe)
NAS (North American specification)
Japan, Middle East, Australia and South Africa

A button, located adjacent to the DVD slot, is provided to eject the DVD from the unit. Prior to ejecting the disc the slot protection has to be slid to the side. If the ignition is on, or the entertainment system is in 1-hour mode, one press of the
button will eject the DVD.
The navigation computer uses non-volatile memory to store settings and configuration information when it is powered down.
This process takes place just before the computer turns off.

No configuration procedure is required if the navigation computer is replaced. There is no option to calibrate the navigation
computer using the Jaguar approved diagnostic equipment; however in some regions a software download, contained in the
DVD disc, is required before the navigation system becomes operational.
MICROPHONE



A single microphone is used for hands-free operation using the JaguarVoice system. The microphone has an integrated noise
suppression system for hands-free use. The microphone is a standard directional type and is located in the front roof overhead
console. The microphone is hardwired to the IAM (integrated audio module). When replacing the microphone extra care must be
taken to make sure it is fitted into its securing clips for correct positioning and orientation.

GPS Antenna


The GPS antenna passes signals from the GPS satellites to the navigation computer for processing. The antenna is located in

the roof pod and is shared with the DAB (digital audio broadcasting) band L antenna or satellite radio antenna where fitted.
The roof pod is located externally in a central position towards the rear of the roof.

The GPS antenna is designed with 50 ohm output impedance. The navigation computer is fitted with 50 ohm fakra II connectors to ensure compatibility with the antenna. For optimum performance 50 ohm low loss coaxial cable is used between
the antenna and navigation computer.
It is possible for the GPS antenna to lose the signal from the GPS satellites; In hilly or tree lined areas
Built up areas with tall buildings
In multi storey car parks
In garages
In tunnels
On bridges
During heavy rain or thunderstorms

When the signal is lost the navigation computer will continue to give guidance using memory mapped data from the DVD map until the signal is restored.

TMC/VICS FM Antenna

Data messages for both TMC (traffic message channel) and VICS (vehicle information and communication system) are received
through the FM antennas and diversity antenna module located in the heated rear window.
VICS Beacon Antenna (Japan Only)



The VICS (vehicle information and communication system) beacon antenna receives infra red and RF (radio frequency) traffic
data signals from road side transmitters. The antenna is connected to the navigation computer which incorporates a VICS
(vehicle information and communication system) receiver.

Touch Screen Display


The Touch-screen is the control interface for the following vehicle systems;

System Functions Audio Radio display AM/FM or DAB (digital audio broadcast), auxiliary and portable audio, digital TV or CD Climate
