AMC-18

AMC-18 is a geostationary Lockheed Martin A2100A communications satellite owned by SES Americom. It was launched on December 8, 2006 from Kourou aboard an Ariane 5 launch vehicle and is situated at 105° west longitude, providing coverage of North America with twenty-four C band transponders of 12-18 watts each. Future users in May 2007 include The CW Television Network, NASA TV and Canadian Broadcasting Corporation, among other services.

AMC-18 is used by thousands of terrestrial radio stations for network feeds using ground equipment from Starguide, X-Digital Systems, Wegener and International Datacasting. Major tenants are Cumulus Media Networks Satellite Services (which includes Citadel Media, Westwood One Networks, Talk Radio Network, WOR Radio Network and others), Skyview Networks (which includes ABC News, ABC Radio, California News Network, Arizona News Network, numerous Professional and Collegian Sports networks, and others), Orbital Media Networks (which includes United Stations Radio Networks, John Tesh, and others), Premiere Radio Networks, Dial Global, Westwood One, Learfield Communications, The Free Beer and Hot Wings Show, etc.

The spacecraft can deliver and receive signals from 50 states, the Caribbean and Mexico and has been designated as the third HD-PRIME satellite.

Originally built as a ground spare to the AMC-10 and AMC-11 satellite program, AMC-18 is optimized for digital television distribution from the center of the U.S. orbital arc.[3]

The satellite has an expected lifetime of at least 15 years.

AMC-8

AMC-8, also known as Americom-8 and Aurora III, previously GE-8, is a C-band satellite located at 139° West, covering the United States, Canada and the Caribbean. It is owned and operated by SES World Skies, formerly SES Americom and before that GE Americom. The satellite, provides critical telecommunications services to AT&T Alascom which occupies most of the satellite's capacity. AMC-8 was launched in 2000 as GE-8, and replaced Satcom C-5 in March 2001.

AMC-8 was used by thousands of terrestrial radio stations for network feeds using ground equipment from Starguide, X-Digital Systems, Wegener and International Datacasting. Major tenants were Cumulus Media Networks Satellite Services (which includes Citadel Media, Talk Radio Network, WOR Radio Network and others), Skyview Networks (which includes ABC News, ABC Radio, California News Network, Arizona News Network, numerous Professional and Collegian Sports networks, and others), Orbital Media Networks (which includes United Stations Radio Networks, John Tesh, and others), Premiere Radio Networks, Dial Global, Westwood One, Learfield Communications, The Free Beer and Hot Wings Show (Transponder 15), and others. However, these were moved over to another satellite, AMC-18. Audio network transmissions on AMC-8 ended as of midnight June 30, 2017.

Since AMC-8 is past its design life, it will soon be decommissioned. As of July 1, 2017 there are no plans to put another satellite in AMC-8's orbital slot (139 degrees).

It carries 24 36 MHz G/H band (IEEE C band) transponders, with 20 watt SSPA amplifiers. Its amplifier redundancy is 16 for 12, and its receiver redundancy is four for two. It carries two beacons, one broadcasting on a horizontal frequency of 3700.5 MHz, and the other on a vertical frequency of 4199.5 MHz.

Headend in the Sky

Headend in the Sky (HITS) is Comcast's satellite multiplex service that provides cable channels to cable television operations.

At a traditional cable television headend, multitudes of satellite dishes and antennas are used to grab cable stations from dozens of communication satellites. In contrast, HITS combines cable stations into multiplex signals on just a few satellites; cable television companies can then pull in hundreds of channels at the local headend with relatively little equipment; the HITS feed effectively replaces the more complex traditional headend operations.

HITS was founded in 1994 and its namesake product is commonly recognized as the pioneer of digital television in the United States. HITS was launched by TCI before their later 1999 purchase by the old AT&T, then merged with the smaller Comcast in 2002 as part their purchase of AT&T Broadband (formerly TCI). The HITS headquarters in Centennial, Colorado, formerly known as the National Digital Television Center, is now called the Comcast Media Center.

As of 2010, HITS offers 6 standard-definition multiplexes on SES Americom's SES-1, 12 standard-definition multiplexes and 8 HD multiplexes on AMC-18, 1 standard-definition multiplex on AMC-10, and 1 standard definition multiplex on Intelsat's Galaxy 17. As of 2010, HITS delivers more than 280 digitally compressed video and audio television programming signals to more than 2000 cable operation sites across the US.
