Vinasat-2
Vinasat-2 (stylized all uppercase) is the second Vietnamese satellite to be placed in orbit. It was launched at 22:13 UTC on May 15, 2012 (5:13am on May 16 in the Vietnam time zone) at the European Spaceport in Kourou in French Guiana in South America and entered orbit 35 minutes later. VINASAT is the national satellite program of Vietnam. The project aims to bring independence in satellite communications for Vietnam, besides other benefits such as enhancing national security, opening new economic opportunities, etc. Vietnam hopes for some economic benefits from the telecommunications links that the satellite will provide. It will provide communication for fishermen at sea, deliver weather forecasts and ensure defence security. The satellite costs about US$280 million and weighing , was constructed by US-based Lockheed Martin. It will be able to provide capacity equal to 13,000 channels of telephone/internet/data communications or 150 Television channels; greater number of se ...

Ariane 5
Ariane 5 is a retired European heavy-lift space launch vehicle operated by Arianespace for the European Space Agency (ESA). It was launched from the Guiana Space Centre (CSG) in French Guiana. It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. 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, first launched in 2024. The system was designed as an expendable launch vehicle 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 was classified as part of the Ariane rocket family. Aérospatiale, and later ArianeGroup, was the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European con ...

Vinasat-1
Vinasat-1 (stylized all uppercase) is a satellite launched by Vietnam, marking a significant achievement for the nation. The launch took place on April 18, 2008, at 22:17 GMT, using an Ariane 5 ECA rocket from the Guiana Space Centre in Kourou, French Guiana, facilitated by Arianespace. Vinasat is the national satellite program of Vietnam, aimed to facilitate telecommunications links in the country. Vietnam hopes to achieve various economic benefits due to the improved telecommunications links that the satellite will provide. Vietnam also hopes to provide radio, television, and telephone access throughout the country. Vinasat-1’s launch was postponed from its original plan in 2005. This was due to its frequency coordination procedures' complexity, which required adherence to the Radio Regulations of the International Telecommunication Union (ITU). Satellite operations for Vinasat-1 were under the management of Lockheed Martin Commercial Space Systems (LMCSS), as per the delivery ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a Transponder (satellite communications), transponder; it creates a communication channel between a source transmitter and a Radio receiver, 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 radio waves used for telecommunications links travel by Line-of-sight propagation, line of sight and so are obstructe ...

Communications Satellites In Geostationary Orbit
Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether unintentional or failed transmissions are included and whether communication not only transmits meaning but also creates it. Models of communication are simplified overviews of its main components and their interactions. Many models include the idea that a source uses a coding system to express information in the form of a message. The message is sent through a channel to a receiver who has to decode it to understand it. The main field of inquiry investigating communication is called communication studies. A common way to classify communication is by whether information is exchanged between humans, members of other species, or non-living entities such as computers. For human communication, a central contrast is between verbal and non-verbal communication. Verbal communication involves the exchange of messages in linguistic form ...

Satellites Of Vietnam
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation (GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which are small CubeSats. Similar satellites can work together as groups, forming constellations. Becaus ...

Spacecraft Launched In 2012
A spacecraft is a vehicle that is designed to fly and operate in outer space. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific research are sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunications In Vietnam
Communications in Vietnam include the use of telephones, radio, television and Internet. Telephones Vietnam is putting considerable effort into modernization and expansion of its telecommunication system. Domestically, all provincial exchanges are digitalized and connected to Hanoi, Da Nang and Ho Chi Minh City by fiber optic cable or microwave radio relay networks. Main lines have been substantially increased, and the use of mobile telephones is growing rapidly. As of 2012, there were 134 million mobile phone subscribers, making Vietnam's rank 6th in the world. Two satellite earth stations are in use: Intersputnik (Indian Ocean region). The incumbent operator is the Vietnam Posts and Telecommunications Group, which spun off from the Department General of Posts and Telecommunications after the separation of regulatory and commercial functions of the latter in 1990. Following the creation of a separate regulatory entity, market segments were opened to competition, starting with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
