Recently Sirius XM added a new satellite to the Sirius fleet that operates in a geostationary orbit, and soon will be launching two new satellites to join the XM and Sirius fleets, both operating in geostationary orbits. This paper provides an overview of the Sirius and XM broadcast system designs and applications, and describes the coverage benefits achieved through the employment of geosynchronous and geostationary space segments in the North American continent.
In addition to presenting the operational satellite radio conditions in the US, we will provide a discussion on offering similar services in the rest of the world with respect to possible satellite and repeater network structures with particular attention in Europe. We will discuss the latitude and longitude aspects for various regions of the world, and discuss the expected QoS levels using conventional SDARS satellite and repeater architectures.
