The television signal goes from the television station´s control room, via cable to the Kaknäs TV-tower in Stockholm. From there, 54 large transmitters receive and distribute the signal throughout the country, with 600 smaller slave transmitters. Additionally, an aerial antenna sends the signal into outer space, where it is received by the Sirius II satellite. This satellite floats above the earth in an orbital path three times larger than the diameter of the earth. Like all other television satellites, its orbit is fixed above earth’s equatorial line. Today, there are nearly 250 satellites like Sirius II orbiting the earth, each with a distance of 500 to 1000 km between them, ringing the earth like a string of pearls.
