Intelsat
Intelsat S.A. (formerly INTEL-SAT, INTELSAT, Intelsat) is a multinational satellite services provider with corporate headquarters in Luxembourg and administrative headquarters in Tysons Corner, Virginia, United States. Originally formed as International Telecommunications Satellite Organization (''ITSO'', or INTELSAT), from 1964 to 2001, it was an intergovernmental consortium owning and managing a constellation of communications satellites providing international telecommunications and broadcast services. As of June 2022, Intelsat operated a fleet of 52 communications satellites which was then one of the world's largest fleets. In 2020, the company announced plans to procure, build and launch seven C-band satellites over the next several years. These C-band satellites will contribute to the acceleration of America's 5G buildout. In early 2022, the company announced contracts for four GEO software defined satellites (SDS), two in partnership with Airbus and two in partnership ...

Intelsat III F-4
Intelsat III F-4 was a geostationary communications satellite built by TRW, it was owned by Intelsat, a company currently based in Luxembourg. The satellite had an estimated useful life of 5 years. The Intelsat III F-4 was part of the Intelsat III series which consisted of eight satellites, which were used for retransmission of global commercial telecommunications, including live TV. The satellite was stabilized by rotation with a minus antenna structure (its antenna was 34 inches high). It had a hydrazine propulsion system with four propellers and four tanks. Passive thermal control. With solar cells producing 178W peak, nine Ahr NiCd batteries. The load consisted of two transponders that used 12 watt TWTA amplifiers for multiple access, 1500 audio circuits or four TV channels. The Intelsat III F-1 was disabled due to launch vehicle failure. The satellite was successfully launched into space on May 22, 1969, by means of a Delta M vehicle from Cape Canaveral Air Force Station ...

Intelsat IV F-3
Intelsat IV F-3 was a geostationary communication satellite built by Hughes, it was owned by Intelsat. The satellite was based on the HS-353 platform and its estimated useful life was 7 years. History The Intelsat IV F-3 was part of the Intelsat IV series which consisted of 6 satellites, of which five were successfully placed into orbit. All five satellites in the series were retired and operated an average of almost 4 years beyond their life expectancies. The satellite antenna allowed coverage from the land masses on both sides of the Atlantic basin with four point beams and had sufficient insulation between the east beams and the western beams that used the same frequencies in the east and west. The separation of the beam by directional antenna allowed this dual use of the frequency, significantly increasing the capacity of satellite communication within an assigned frequency range. Although the initial requirement Intelsat VAT series was only for the Atlantic service, but al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cape Canaveral Launch Complex 36
Launch Complex 36 (LC-36)—formerly known as Space Launch Complex 36 (SLC-36) from 1997 to 2010—is a launch complex at Cape Canaveral Space Force Station in Brevard County, Florida. It was used for Atlas (rocket family), Atlas launches by NASA and the U.S. Air Force from 1962 until 2005. Blue Origin has leased the launch site since 2015 in order to build a new launch site for launching the company's orbital spaceflight, orbital rockets. Orbital launches are expected to begin from LC-36 no earlier than Q4 2022, and the first launch vehicle slated to launch there is New Glenn, under development by Blue Origin since 2012. As of 2019, LC-36 is under major construction, including for a large launch pad for the launch vehicle with nearby Horizontal Integration Facility, lightning tower, water tower, and propellant tank farm for liquid methane and liquid oxygen. Historically, the complex consisted of two launch pads, SLC-36A and SLC-36B, and was the launch site for the Pioneer progra ...

Atlas-Centaur
The Atlas-Centaur was a United States expendable launch vehicle derived from the SM-65 Atlas D missile. Launches were conducted from Launch Complex 36 at the Cape Canaveral Air Force Station (CCAFS) in Florida. Early development Convair, the manufacturer of the Atlas, developed the Centaur upper stage specifically for that booster, sharing its pressure stabilized tank structure. Technical Centaur was the first rocket stage to utilize liquid hydrogen (LH2) and liquid oxygen (LOX) as propellants. Despite high performance, LH2 had to be chilled at extremely low temperatures (lower than LOX) and its low density meant that large fuel tanks were needed. The first attempt at using an LH2/LOX-fueled engine was the U.S. Air Force's top-secret Lockheed CL-400 Suntan reconnaissance aircraft program in the mid-1950s. The progress made during the aborted venture was picked up by Convair and others for rocket stage use. Originally, Centaur was conceived of as a purely experimental proje ...

Intelsat III F-8
Intelsat III F-8 was a communications satellite owned by Intelsat. The satellite had an estimated useful life of 5 years. Design The last of eight Intelsat III satellites to be launched, Intelsat III F-8 was built by TRW. It was a spacecraft equipped with two transponders to be powered by body-mounted solar cells generating 183 watts of power. It had a design life of five years and carried an SVM-2 apogee motor for propulsion. Launch Intelsat III F-8 was launched on a Delta M rocket, flying from Launch Complex 17A at the Cape Canaveral Air Force Station. The launch took place on July 23, 1970, with the spacecraft bound for a geosynchronous transfer orbit. The Intelsat III F-8 was lost due to a malfunction during the apogee motor firing. Communications stopped 14.5 seconds into the planned 27 second apogee motor burn.
