As with other line-of-sight broadcasts, such as
cellular telephone and FM-radio signals,
temporary loss of signal may occur when
passing obstacles such as expressway over-
passes, tunnels, bridges, etc. Audio will be
fully restored when your vehicle clears the
obstacle.
The Sirius satellite system consists of 3
satellites at a high-elevation geosynchronous
orbit. They provide a superior line-of-sight
coverage across the continental US.
The Sirius Satellite Radio constellation and
orbit were selected to provide high elevation,
continuous coverage to the Continental United
States. The elevation is achieved by using a
highly inclined orbit. Continuous coverage is
achieved by utilizing three satellites in a
constellation. The orbit is a highly inclined,
elliptical orbit with a 24-hour period.

The Volvo Sirius Satellite radio system consists
of three main components:
(1) the Volvo satellite antenna, which receives
the Sirius broadcast signal.
(2) the Volvo receiver, which decodes the audio
and data information.
(3) the Volvo radio main unit, which controls
and displays the audio and data informa-
tion.
