SPACEWAY-2
Spaceway-2 is part of DirecTV's constellation of direct broadcast satellites. The satellite was launched via an Arianespace Ariane 5 ECA rocket from Kourou, French Guiana on 16 November 2005. Its operational position is in geosynchronous orbit above the equator at 99.2° West longitude. Spaceway-2 is a Boeing 702-model satellite with a 12-year life expectancy. It is expected to support high-definition television to DirecTV customers with its Ka-band communications payload. Although Spaceway-2 was originally built by Boeing to be used for broadband Internet access via Hughes Network Systems, it has been retrofitted to deliver HD local channels (NBC, ABC, CBS, and Fox) to numerous markets nationwide. On 19 April 2006, the satellite was delivered to DirecTV's control after successful on-orbit testing. Spaceway-2 immediately started broadcasting HD locals to DirecTV customers in eight more markets: Minneapolis, Minnesota; Sacramento and San Diego, California; Pittsburgh, Penns ...

Ariane 5
Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development. The system was designed as an expendable launch system by the ''Centre national d'études spatiales'' (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it is classified as part of the Ariane rocket family. ArianeGroup is the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally intende ...

Spaceway
The Spaceway system was originally envisioned as a global Ka band, Ka-band communications system by Hughes Electronics. When the project to build the system was taken over by Hughes Network Systems, a subsidiary of Hughes Electronics, it was transformed into a phased deployment initially only launching a North American satellite system. This is in comparison to other more ambitious systems such as Teledesic and Astrolink which retained their full global nature and which subsequently failed to complete their systems. Hughes Network Systems working with Hughes Electronics subsidiary Hughes Space and Communications (and subsequently sold to Boeing and called Boeing Satellite Development Center, Boeing Satellite Systems and later the Boeing Satellite Development Center) completed and built the North American Spaceway system meant to provide Internet access, broadband capabilities of up to 512 kbit/s, 2 Mbit/s, and 16 Mbit/s uplink data communication rates with fixed Ka-band satellite t ...

Spaceway-3
Spaceway-3 is a communications satellite which was launched in August 2007. The third satellite in the Spaceway series, it includes a Ka-band communications payload. It is used by Hughes Network Systems to provide broadband Internet Protocol network service. History In March 2007, shortly after the failure of a Sea Launch rocket launch in January 2007, Hughes Network Systems switched launch of Spaceway-3 from a Zenit-3SL rocket to an Ariane 5 launch vehicle. Launch Spaceway-3 was launched 14 August 2007 on an Ariane 5 launch vehicle with BSAT-3a. It lifted off at 23:44 UTC from ELA-3 of the Centre Spatial Guyanais. Five hours and 46 minutes later, signals from the spacecraft were successfully received at a ground station in Hartebeesthoek, South Africa South Africa, officially the Republic of South Africa (RSA), is the Southern Africa, southernmost country in Africa. It is bounded to the south by of coastline that stretch along the Atlantic Ocean, South Atlant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Fox Broadcasting Company
The Fox Broadcasting Company, commonly known simply as Fox and stylized in all caps as FOX, is an American commercial broadcast television network owned by Fox Corporation and headquartered in New York City, with master control operations and additional offices at the Fox Network Center in Los Angeles and the Fox Media Center in Tempe. Launched as a competitor to the Big Three television networks ( ABC, CBS, and NBC) on October 9, 1986, Fox went on to become the most successful attempt at a fourth television network. It was the highest- rated free-to-air network in the 18–49 demographic from 2004 to 2012 and again in 2020, and was the most-watched American television network in total viewership during the 2007–08 season. Fox and its affiliated companies operate many entertainment channels in international markets, but these do not necessarily air the same programming as the U.S. network. Most viewers in Canada have access to at least one U.S.-based Fox affiliate, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Access
Internet access is the ability of individuals and organizations to connect to the Internet using computer terminals, computers, and other devices; and to access services such as email and the World Wide Web. Internet access is sold by Internet service providers (ISPs) delivering connectivity at a wide range of data transfer rates via various networking technologies. Many organizations, including a growing number of municipal entities, also provide cost-free wireless access and landlines. Availability of Internet access was once limited, but has grown rapidly. In 1995, only percent of the world's population had access, with well over half of those living in the United States, and consumer use was through dial-up. By the first decade of the 21st century, many consumers in developed nations used faster broadband technology, and by 2014, 41 percent of the world's population had access, broadband was almost ubiquitous worldwide, and global average connection speeds exceeded one me ...

Life Expectancy
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, current age, and other demographic factors like sex. The most commonly used measure is life expectancy at birth (LEB), which can be defined in two ways. ''Cohort'' LEB is the mean length of life of a birth cohort (all individuals born in a given year) and can be computed only for cohorts born so long ago that all their members have died. ''Period'' LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year. National LEB figures reported by national agencies and international organizations for human populations are estimates of ''period'' LEB. In the Bronze Age and the Iron Age, human LEB was 26 years; in 2010, world LEB was 67.2 years. In recent years, LEB in Eswatini (formerly Swaziland) is 49, while LEB in Japan is 83.
