American Satellite Company (ASC) was one of many Fairchild Industries subsidiary companies and was established in partnership with Continental Telephone [1] in 1972. [2] Emanuel Fthenakis was the President and Chief Executive Officer upon the founding of the corporation. [1] He was replaced in 1976 by Harry Dornbrand, [3] who was President of Fairchild Space and Electronics division at the time. Under their leadership, ASC pioneered advancements in satellite broadcasting both domestically and abroad.
In June 1973 ASC became the first company to transmit United States domestic television via satellite. [4] The first broadcast was of an address by then Speaker of the House Carl Albert delivered in Washington, D.C., and sent to the National Cable Television Association convention in Anaheim, California. [4]
On the same day, they became the first company to broadcast a major sports event via satellite: the fight between Jimmy Ellis and Ernie Shavers in Madison Square Garden. [4]
ASC was headquartered in Rockville, Maryland, and had 4 Earth stations located in SFES - San Francisco, CA (Benicia), LAES - Los Angeles, CA (Nuevo), DAES – Dallas, TX, NYES – New York, NY.
In 1976 ASC began commercially delivering The Wall Street Journal via satellite. [5]
In 1982 ASC began commercially delivering the fledgling USA Today via satellite.
ASC contributed to Department of Defense communications systems and built the first digital satellite route from Hawaii to the U.S. mainland via a land base in California. [6] The corporation also invented a shipboard antenna that could connect military vessels to satellite communications despite the pitch and yaw motion of the ship. [7]
By 1978 ASC "established the first wideband digital data transmission service via domestic satellite for the Defense Meteorological Satellite Program". [8]
In 1984, the corporation control became the largest U.S. transceiver satellite communications network.
The Transmission Operations department was responsible for operations and maintenance. The Network Operations Control Center was located at Vernon, NJ, and was later relocated to Ellenwood, DeKalb County outside of Atlanta, GA.
At the end of 1987, the Southeast Region consisted of the following sites:
American Satellite initially leased satellite service on the Western Union WESTAR satellites. American Satellite contracted with RCA Astro to build the ASC-1 satellite which was launched via NASA space shuttle Discovery mission STS-51-I on August 27, 1985. The satellite has 18 C-band and 6 Ku-band transponders. On C-band, the satellite had 12 each 36 MHz transponders that used Solid State Power Amplifiers (SSPAs) and 6 each 72 MHz transponders that used Traveling Wave Tube Amplifiers (TWTAs). The SSPAs had 8.5 watts of Radio Frequency (RF) power and the TWTAs had 16.2 watts of RF power. On Ku-band the satellite had 6 each 72 MHz transponders. The satellite had a Horizonal polarity beacon at 4100 MHz, a Vertical polarity beacon at 3700 MHz. The Satellite was parked at 81 degrees west. ASC-2 was launched via a Delta-7925 rocket from Cape Canaveral on April 3, 1991 and was parked at 101 degrees west. ASC-3 was not used and sold to PanAmSat.
The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by the Indian Space Research Organisation (ISRO) to satisfy telecommunications, broadcasting, meteorology, and search and rescue operations. Commissioned in 1983, INSAT is the largest domestic communication system in the Indo-Pacific Region. It is a joint venture of the Department of Space, Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. The overall coordination and management of INSAT system rests with the Secretary-level INSAT Coordination Committee.
Telkom-2 was a geosynchronous communications satellite built by Orbital Sciences Corporation (OSC) for Indonesia's state-owned telecommunications company, PT Telekomunikasi Indonesia Tbk. Telkom-2 was successfully launched on 16 November 2005, at 23:46:00 UTC and positioned in geostationary orbit, at 118° East for replaced Palapa-B4.
JCSAT-5A or N-STAR d, known as JCSAT-9 before launch, is a geostationary communications satellite operated by SKY Perfect JSAT Group (JSAT), which was designed and manufactured by Lockheed Martin on the A2100 platform.
T10 is a Boeing model 702 direct broadcast satellite that provides high-definition television (HDTV) to DirecTV subscribers in North America. It was launched by International Launch Services on July 7, 2007 from the Baikonur Cosmodrome in Kazakhstan aboard an Enhanced Proton Breeze-M rocket. After about two months of in-orbit testing, the satellite was moved to its operating position at 103.0° west longitude. This was the third DirecTV satellite launched on a Proton rocket. Prior launches include T8, which was launched on May 22, 2005, and T5, which was launched on May 7, 2002. The satellite was renamed to T10 in 2017.
A communications satellite's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. It is mainly used in satellite communication to transfer the received signals.
LDMOS is a planar double-diffused MOSFET used in amplifiers, including microwave power amplifiers, RF power amplifiers and audio power amplifiers. These transistors are often fabricated on p/p+ silicon epitaxial layers. The fabrication of LDMOS devices mostly involves various ion-implantation and subsequent annealing cycles. As an example, the drift region of this power MOSFET is fabricated using up to three ion implantation sequences in order to achieve the appropriate doping profile needed to withstand high electric fields.
AMC-8, also known as 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-C5 in March 2001.
ARSAT-2 is a geostationary communications satellite operated by ARSAT and built by the Argentine company INVAP. It was launched from French Guiana alongside Sky Muster satellite using an Ariane 5ECA rocket on September 30, 2015 at 20:30hs UTC, becoming the 400th satellite to be launched by Arianespace. It is licensed to be located at 81° West longitude geostationary slot. ARSAT-2 is the second geostationary satellite built in Argentina, after ARSAT-1.
