Programs are beamed to one of the three Sirius satellites -- the satellites then transmit the signal to the ground, where your radio receiver picks up one of the channels within the signal. Signals are also be beamed to ground repeaters for listeners in urban areas where the satellite signal can be interrupted.
Sirius produces car radios and home entertainment systems, as well as car and home kits for portable use. The Sirius receiver includes two parts: the antenna module and the receiver module. The antenna module picks up signals from the ground repeaters or the satellite, amplifies the signal and filters out any interference. Inside the receiver module is a chipset consisting of eight chips. The chipset converts the signals from 2. Sirius also offers an adapter that allows conventional car radios to receive satellite signals.
Sirius partnered with several car manufacturers to create a service that broadcasts programming from Nickelodeon, the Cartoon Network and the Disney Channel that televisions with special Sirius receivers can pick up. People riding in the front of the vehicle can still listen to other Sirius radio stations while the kids watch television in the back. So far, 1worldspace has been the farthest-reaching company in the satellite radio industry.
It put two of its three satellites , AfriStar and AsiaStar , in geostationary orbit before either of the other two companies launched one. AmeriStar , which will offer service to South America and parts of Mexico, has not yet been launched. Each satellite transmits three signal beams, carrying more than 60 channels of programming, to three overlapping coverage areas of about 5. Each of the 1worldspace satellites' three beams can deliver more than 50 channels of crystal-clear audio and multimedia programming via the 1, to 1,megahertz MHz segment of the L-Band spectrum , which is allocated for digital audio broadcasting.
The United States is not currently part of 1worldspace's coverage area, although the company has invested in Sirius XM Radio and has an agreement with the company to share any technological developments. That might be overstating the company's intent a bit, but 1worldspace does plan to reach the corners of our world that most radio stations can't.
There are millions of people living in 1worldspace's projected listening area who can't pick up a signal from a conventional radio station. The satellite then transmits the signal in one, two or all three beams on each satellite.
Receivers on the ground then pick up the signal and provide CD -quality sound through a detachable antenna. The receivers use the proprietary StarMan chipset, manufactured by STMicroelectronics, to receive digital signals from the satellites.

This electromagnetic radiation is called synchrotron light. Synchrotron light is not emitted in all directions, it is concentrated in the direction tangent to the curve made by the electrons. For this reason, around the particle accelerators, research stations, called beamlines, are installed, which prepares the synchrotron light to illuminate the samples of the materials to be analyzed. In an equipment called electron gun, these particles are initially emitted from a hot metal plate.
Next, the electrons are accelerated by oscillating electric fields to speeds close to the speed of light. Then, the particles are transferred to the Injector Accelerator, or Booster. The electrons coming from Linac travel around this circular accelerator thousand times every second. With each loop, the particles have their energy increased until they reach the necessary energy to be transferred to the Main Accelerator, or Storage Ring. In the main accelerator, electrons are kept circulating for hours and hours in stable orbits, guided by magnets.
