XM Satellite Radio and Sirius Satellite Radio have designed satellite broadcast systems that differ but they achieve the same high quality of satellite radio. A milestone of this success is the fact that satellite radio signals that are available across the United States and into Mexico and Canada. Rock and Roll – No its not a genre any more! XM Satellite Radio has two satellites named Rock and Roll which remain in parallel geostationary orbit to provide radio coverage throughout the United States. Sirius Satellite Radio has chose to use three satellites in an inclined elliptical orbit. This configuration provides 16 hours per satellite of signal, which gives a great redundancy if any satellite were to fail. Playing it smart, Sirius and XM both have spare satellites, which can be called on in a moments notice if needed.
XM satellite radio and sirius satellite radio have Earth based broadcast stations that are used to send up information to the satellites, which is then dispersed through out the globe. Sirius and XM both have disk jockeys that manage, create and program music which is then sent up to the satellites. The information is then taken in by the satellites and sent through a rebroadcast of the streams to earth. The Major advantage of this is that, unlike earth-based radio stations whose signals reach listeners 150 miles away, satellite radio signals have a huge reach, and are receivable anywhere within the continental United States and hundreds of miles in each direction of the borders. Satellite Radio is growing to become a world wide network and offerings are growing throughout the world. XM satellite radio and Sirius satellite radio are making it happen!
So How Does Satellite Radio Work: First, a receiver decodes and plays the received signals through an antenna. In the beginning, some cars have used a tuner that accepts the antenna signals and then passes them to a satellite radio-ready radio for playing. Ad the concept has grown out of the car and into the home, home kits for satellite radio use direct RCA inputs for home theater and traditional stereo systems. A Growing number of choices is occurring and each company is developing a broad scope of products for consumers. Already we are seeing receivers for car-only, boom boxes, computer-only, and portables for use in car and home configurations. The companies making these products are, Audiovox, Delphi Skyfi, Terk, and plenty others are jumping on board. Both XM satellite radio and Sirius satellite radio have licensed recievers and other products for consumers use.
