The advantage of this orbit is that the satellite's orbital period equals the rotation rate of the Earth, so the satellite appears at a fixed position in the sky. Thus the satellite dish antenna which receives the signal can be aimed permanently at the location of the satellite, and does not have to track a moving satellite. A few systems instead use a highly elliptical orbit with inclination of +/?63.4 degrees and orbital period of about twelve hours, known as a Molniya orbit. Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. Uplink satellite dishes are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter. The increased diameter results in more accurate aiming and increased signal strength at the satellite. The uplink dish is pointed toward a specific satellite and the uplinked signals are transmitted within a specific frequency range, so as to be received by one of the transponders tuned to that frequency range aboard that satellite. The transponder re-transmits the signals back to Earth at a different frequency (a process known as translation, used to avoid interference with the uplink signal), typically in the 10.7-12.7 GHz band, but some still transmit in the C-band (4b8 GHz), Ku-band (12b18 GHz), or both. The leg of the signal path from the satellite to the receiving Earth station is called the downlink ------------------------------ End of alt.music.moxy-fruvous digest V14 #3794 **********************************************
