Digital radio reception
The "Sirius Satellite Radio Inc." radio station records the radio programs in digital form. Parabolic antennae
transmit the signals to the 3 Sirius satellites.
The digital signals are transmitted back to Earth as follows:
•
2 satellites transmit to all parts of the Earth. The signals are received by the car's SDARS antenna for
satellite reception.
•
1 satellite transmits the digital signals to stationary antennae for terrestrial reception. The antennas
transmit digital signals in all directions. The vehicle's SDARS antenna for terrestrial reception receives
these digital signals.
Different reception paths for digital signals ensure that reception is good even if there is no direct visual contact
between the vehicle and the Sirius satellites.
If there is not direct visual contact, the signal will be received via the stationary antennae for terrestrial reception.
Satellite reception can be prevented by topographical and constructional features (e.g. valleys, skyscrapers,
tunnels).
Very good reception across the entire region covered is achieved through the following measures:
•
Satellites positioned in a high elliptical orbit
•
Use of additional stationary antennae for terrestrial reception
