Galaxy 18 is a Space Systems/Loral (SS/L) 1300-series hybrid communications satellite owned by Intelsat and located in geosynchronous orbit at 123° W longitude, serving the continental United States, Alaska, Hawaii, Mexico, and Canada with 24 C-band, and 24 Ku-band transponders. Galaxy 18 is intended to replace Galaxy 10R which was nearing the end of its design life.[1]
While this spacecraft is designed for a 15-year service life on orbit, Sea Launch’s direct insertion[citation needed] into equatorial orbit is expected to yield additional years of fuel life. Galaxy 18 was scheduled to be launched by Sea Launch on May 8, 2008 but was pushed to May 25[citation needed]. It was subsequently moved up to 21 May. The launch took place successfully at 09:43 GMT.[2]
Free-to-air television
Galaxy 18 is the home of many free-to-air television channels, including approximately three dozen US local stations operated by Equity Broadcasting. Ku band DVB-S programming may be received by compliant FTA receivers throughout North America using satellite dishes as small as one metre.[3]
As of 2008, available free-to-air channels at 123°W include:
- ABC TV (KATV, KKTU, KTWO)
- Daystar TV
- Fox TV (KBTZ, KLMN, KMMF, WMQF)
- KWWF (Ind. - Waterloo, Iowa)
- Multimedios Television (KMCC)
- My Network TV (KFDF, KPBI, KWBF, KWBM, WGMU)
- Retro Jams
- RTN Radio
- Telefutura (KAMT, KUTF)
- This TV (KCBU, KEGS, KKYK, KQDK, KQUP, KTVC,KWCE, WNGS, WPXS)
- Univisión (KEYU, KUTH, KUWF, KXUN, WNYI, WUMN)
- University of Washington TV and the Research Channel
- Veterans Affairs Knowledge Network
Free ethnic programming includes Aaj TV, Hum TV, Peace TV and TV One (Pakistan).
All Equity Media-owned stations are programmed from a central hub in Little Rock, Arkansas, with the satellite feeds used to deliver the complete signals to the individual station transmitter sites and to cable television operators. The future status of these stations is unknown, as Equity Media Holdings filed for chapter 11 bankruptcy on December 8, 2008.
