7 Triple TV antenna module 8 RF filter The diversity antenna module, located on the left hand side of the heated rear window, receives signals from four antennas
located in the heated rear window, where one antenna is dedicated as an AM antenna.

The diversity tuning system ensures that the strongest signals are used by the radio system to ensure the best possible FM
reception. Using the three remaining receiving antennas serves to eliminate multipath signal distortion. Typically, the signal
from the antenna with the least noise is chosen, and the other antennas are ignored.

The diversity antenna module is an interface between the antenna aerials in the heated rear window and audio system
modules/tuners. It provides antenna signals to the AM/FM tuner in the IAM, to the DAB receiver and to the VICS (vehicle
information and communication systems) or TMC (traffic message channel) in the navigation computer.

There are three different types of diversity antenna module fitted depending on the vehicle market and infotainment
equipment specification:
AM/FM with one co-axial output
AM/FM and VICS/TMC with two co-axial outputs
AM/FM, VICS/TMC and DAB band III with three co-axial outputs
The diversity antenna module receives a power supply from the IAM.

Vehicle or other component generated electromagnetic interference may cause unwanted disturbances in the radio and TV
reception signals. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the
circuit. It frequently affects the reception of AM radio in urban areas and can also affect FM radio and television reception,
although to a lesser extent.

The RF filters, which act as RF isolators, are located on both sides of the heated rear window and are used to reduce the
electromagnetic interference. The left hand side RF filter is connected across the heated rear window power supply and used to
separate the DC (direct current) interference from the RF signals. The right hand side RF filter is used in conjunction with the
TV antenna module (if fitted). If the TV system is not fitted the filter is linked directly to ground.

INFORMATION CONTROL MODULE



The ICM is located beneath the IAM in the center console. The unit performs a range of infotainment and some climate-control
functions.

The ICM, which is the timing master of the MOST system; supplies clock information to all other devices on the network which
synchronize their operation to this clock.

The unit also controls and manages the MOST ring and provides the allocations of channels, system power management,
functionality and co-ordination of the other system components.

The system becomes operational when the vehicle is unlocked and a 'wake up' signal is received by the ICM on the medium
speed CAN. The ICM 'wakes up' all the control modules on the MOST system ready for immediate operation by the vehicle user. If the ICM is replaced it must be configured as a new module using the Jaguar approved diagnostic equipment.

Calibration of the ICM using the Jaguar approved diagnostic equipment enables updates to be downloaded as new technology
becomes available or any fault concerns require software updates.

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.

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.

The GPS signal is also known as the PPS (precision positioning signal). PPS (precision positioning signal) predictable accuracy is:
22 meters horizontal accuracy
27.7 meters vertical accuracy
200 nanoseconds time accuracy

The navigation system receives GPS information via the GPS antenna. The GPS signals are used by the navigation computer to calculate the vehicles position. Once the driver has input a desired destination the navigation computer can calculate a route,
based on the driver's pre-determined preferences or the default settings in the navigation computer.
The navigation system is accessed from the Touch-screen home menu.
Navigation is initiated by the driver inputting a destination. This can be achieved by:
Entering an address using the Touch-screen
Entering a post code
Choosing a previous destination
Choosing a point of interest from the map disc database
Choosing the home location
Choosing a memory stored location

The driver is then guided to the destination by a scrolling map display and voice guidance. The display can be varied by scale
and display type.

In addition to the standard navigation system there are two market dependant systems that supply extra information to the
navigation system and the driver. These are:
TMC (traffic message channel) (Europe only)
VICS (vehicle information and communication system) (Japan only)

The TMC (traffic message channel) is a function of the FM (frequency modulation)RDS (radio data system). The system
broadcasts real-time traffic and weather information. Data messages are received and decoded by the TMC (traffic message
channel) integral receiver and processed by the navigation computer. TMC (traffic message channel) messages can be filtered
by the navigation computer so that only those relevant to the current journey are displayed, allowing the navigation system to
offer dynamic route guidance - alerting the driver of a problem on the planned route and calculating an alternative route to
avoid the incident. All TMC (traffic message channel) events on the map can be viewed not just the ones on the calculated
route.

TMC (traffic message channel) traffic information systems conform to a global standard that has been adopted by traffic data
gatherers, information service providers, broadcasters and vehicle/receiver manufacturers.

All TMC (traffic message channel) receivers use the same list of event codes, while the location database (on the map disc)
contains both a country-specific set of location codes for the strategic European road network.
TMC (traffic message channel) traffic data is currently broadcast in many European countries.
The VICS (vehicle information and communication system) is broadcast in the Japanese market.
The VICS (vehicle information and communication system) 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 3 routes:

RF (radio frequency) transmission
Infra-red transmission
FM multiplex transmissions
The RF (radio frequency) transmissions are generally transmitted from road side beacons mainly on expressways. The
information transmitted is as follows:
Traffic congestion
Travel time to next intersection
Traffic conditions in surrounding areas and expressway turn offs
Traffic accidents
Speed limits
Lane regulations
Tire change
Parking availability at expressway service areas and parking areas
Infra-Red transmissions are transmitted from road side beacons on major trunk roads. The information transmitted is:
Traffic congestion and travel time
Traffic accidents
Breakdowns
Road works restrictions
Parking availability

FM transmissions are broadcast as part of the FM multiplex broadcasting system from NHK FM stations. Information transmitted is:
Traffic congestion and travel time for wide areas
Traffic accidents, road works, speed limits and lane restrictions for a wide area
Parking availability information
The traffic data is split from the normal FM transmissions by the diversity antenna module.
Selection of 'Navigation' on the Touch-screen home menu and subsequent sub-menu selection sends a control request signal to
the navigation computer on the MOST (media orientated systems transport) ring. The requested control information is
processed by the navigation computer.

If voice guidance is operational the voice signal information is relayed from the navigation computer on the MOST (media
orientated systems transport) ring to either the IAM (integrated audio unit) or Power Amplifier, dependant on equipment level,
for output on the speaker system. The navigation audio output is through the front speakers whilst the background audio, for
example radio or CD (compact disc), is played at a reduced volume on the rear speakers.
The GPS signal is available to the navigation system at all times when the vehicle ignition is switched on.
Navigation user voice commands are made using the JaguarVoice system. The ICM (information control module) processes the
analogue signal from the JaguarVoice switch into a digital signal. The digital signal is passed from the ICM (information control
module) onto the MOST (media orientated systems transport) system to the JaguarVoice control unit which is integral with the
navigation computer.

The navigation computer sends an instruction via the MOST (media orientated systems transport) ring to the IAM (integrated
audio module) to turn on the microphone facility.

The microphone is hardwired to the IAM (integrated audio module). The spoken voice command signals are relayed from the
IAM (integrated audio module) via the MOST (media orientated systems transport) ring to the navigation computer for
