The satellite transmits this information both to ground relay stations and autonomous SDARS receivers, including car receivers. The receiver is able to switch from receiving the signal from the satellite to receiving the strongest signal coming from the relay station at any time.
Land Rover uses US provider Sirius Satellite Radio.
The SDARS system includes:
- satellites
- Terrestrial repeaters
- Ground transmitting stations
- Radio reception systems
The SDARS system uses three satellites orbiting the Earth in inclined elliptical orbits. Each satellite is above the US territory for approximately 16 hours, i.e. at least one satellite is above the country at any time.
Signals from satellites are picked up by receivers or sent to repeaters, which allows you to receive transmissions even if the satellite is not in line of sight.
SDARS is a subscription service that requires the user to contact Sirius (to get a subscription). To obtain a subscription, you need to extract the ID-number of the SDARS block from the block. This is done as follows:
- Press the MENU button and then turn the menu knob to scroll through the settings.
- Rotate the menu knob to scroll to the SIRIUS ID and press the menu knob to select it.
- Sirius ID will be shown on the display.
If no subscription has been accepted, ICM will display the Sirius phone number. To subscribe to Sirius services, use the phone number shown. The user will need payment details, a Sirius ID number, and details of the required service package.
The SDARS function is accessed by pressing the FM button and then pressing it again to switch between SAT1 and SAT2 sources. SAT1 and SAT2 work the same as FM1 and FM2.
The SDARS module is located on the left rear of the luggage compartment. The SDARS module is connected to the rest of the audio system via the MOST bus. This allows control signals and received audio signals to pass through the system to the appropriate module. The SDARS antenna is located in an adapter mounted on the roof and has a permanent wired connection to the SDARS module.
