What is the technology used in live telecast?
A communications satellite (sometimes abbreviated to COMSAT) is an artificial satellite stationed in space for the purpose of telecommunications. Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, other elliptical orbits and low (polar and non-polar) Earth orbits. For fixed (point-to-point) services, communications satellites provide a microwave radiorelay technology complementary to that of submarine communication cables. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radio broadcasting, for which application of other technologies, such as cable, is impractical or impossible. A direct broadcast satellite is a communications satellite that transmits to small DBS satellite dishes (usually 18 to 24 inches or 45 to 60 cm in diameter). Direct broadcast satellites generally operate in the upper portion of the microwave Ku band. DBS technology is used for DTH-oriented (Direct-To-Home) satellite TV services, such as DirecTV and DISH Network in the United States, Bell TV and Shaw Direct in Canada, Freesat in the UK and Sky Digital in the UK, the Republic of Ireland, and New Zealand.
Why do communications systems use serial transmission?
because it is cost effective. we use just one wire for transmission
Why do satellites have different aerials and positional orbits?
Satellies have different aerials and positional orbits due to the molecular gravitional pull of the moon and the Earth's surface. The use of the aerials in the satellites assist in the communication between the microwave fields of the transmission towers.
Worldwide collection of computer network?
The Internet uses a worldwide connection of networks. Computers use the global system of networks that are linked through wireless, electronic, and optical networking.
What is the use of network termination unit?
The network termination unit is used to establish communications link between the customer equipment and the local hoop if the local hoop is digital.
Why do the US army use satellites?
Reconnaissance, communications, topography.
How many satellites does the Iridium project use?
It uses 66 small satellites in low earth orbit
What are the names of the 2 martial satellites?
The two military satellites commonly referred to as "martial satellites" are the U.S. Navy's Global Positioning System (GPS) satellites and the U.S. Air Force's Advanced Extremely High Frequency (AEHF) satellites. GPS provides positioning and timing information for military and civilian use, while AEHF satellites enable secure communications for U.S. and allied military forces.
Why does the internet need to use communications satellite?
The internet relies on communications satellites to provide connectivity in remote and underserved areas where traditional infrastructure, like fiber-optic cables, is impractical or too costly to deploy. Satellites facilitate global communication by enabling data transmission across vast distances, ensuring that users can access online services regardless of their geographical location. Additionally, they play a crucial role in enhancing network redundancy and reliability, especially during natural disasters or emergencies when terrestrial systems may fail. Overall, satellites help bridge the digital divide, promoting greater internet accessibility worldwide.
What non-profit organization is made up of worldwide ham radio operators that use their own membership-supported satellites?
Amateur Radio.
Do they make any analog satellite radios for the analog hobbyist?
Satellites use the microwave spectrum.It's almost always digital.Enthusiasts do listen to the Shuttle communications though
How do television networks use communications satellites?
Television networks utilize communications satellites to transmit signals over long distances, enabling the distribution of programming to a broad audience. Satellites receive signals from broadcasting stations and relay them to various ground stations and cable providers, ensuring that viewers can access content regardless of geographic location. This technology enhances the reach of networks, allowing for live broadcasts and the delivery of high-quality audio and video. Additionally, satellites facilitate the delivery of content to cable and satellite TV providers, which then distribute it to consumers.
What tegnology advances have been invented because of space exploration?
Communications, using satellites. Miniturisation, space saving and low power use of electronics, required for use in space vehicles. Medical chemicals researched in space.
Are satellites good or bad?
{| |- | Satellites are neither good nor bad. How they are used can be good or bad. While it is considered good to use their photographs to predict weather patterns, using them to spy on other countries is not considered good, though perhaps necessary. They are critical in today's world in providing communications services throughout the world. |}
Can this phone be used as a GPS with the right software worldwide?
Yes, if you install the Ultra-sync GPS 100-M unit onto your phone, you can use the gps which syncs up with the satellites that orbit the earth.
Do satellites have satellites?
Satellite is probably the most useful invention since the wheel. Satellites have the capability to let you talk with someone across the nation or let you close a business deal through video communication. Almost everything today is heading towards the use of satellites, such as telephones. At&t has used this communications satellite (top right) ever since the late 1950s. TVS and radios are also turning to the use of satellites. RCA and Sony have released satellite dishes for Radio and Television services. New technology also allows the military to use satellites as a weapon. The new ION cannon is a satellite that can shoot a particle beam anywhere on earth and create an earthquake. They can also use it's capability for imaging enhancement, which allows you to zoom in on someone's nose hairs all the way from space
