The Sirius satellite

The satellite used by Sirius is constant delivering digital radio broadcasting to Sirius subscribers. The Most problematic aspects of satellite radio broadcasting is the line of sight – which can be easily interrupted by landscape or buildings the Sirius commercial satellite have a slight advantage over their competitors, since they have a clearer line of sight. The three satellites used for broadcasting slowly orbit around the Earth and only two of them are functional at any time. This is because Sirius only has two transmission frequencies and by alternating satellite transmission they can eliminate interferences while also having a spare satellite to put to use in case something goes wrong with one of the others.

The 3 satellites take turns broadcasting transmission. Since the more inclined orbit provides better coverage, Canada and Mexico are also well covered by the digital broadcasting. This is the best feature of the Sirius satellite radio, as it enhances the benefit of not having to switch radio stations during long trips or while traveling outside US borders. Sirius also collaborates with the Canadian Broadcasting Corporation and Standard Radio Inc.
