Why do we have a satellite in space?
Most of the satellites are for communication - such as tv/radio and mobile phones. There are also the satellites of the Global Positioning System and military satellites.
What are the basic elements of satellite communication systems?
Satellite communication is one particular example of wireless communication systems. Similar and maybe more familiar examples of wireless systems are radio and television broadcasting and mobile and cordless telephones. Systems of this type rely on a network of ground-based transmitters and receivers. They are commonly referred to as 'terrestrial' systems as opposed to satellite systems. these are the following important element in the satellite communication system 1.user 2.terrestrial system 3.earth station 4.repeaters user: user are located on the earth and they produces the baseband signal terrestrial system: terrestrial system can be switch or telephone line or network. the function of terrestrial system is to proceed the baseband signal to the earth station which are coming from the user earth station : Earth station is the common name for every installation located on the Earth's surface and intended for communication (transmission and/or reception) with one or more satellites. Earth stations include all devices and installations for satellite communications: handheld devices for mobile satellite telephony, briefcase satellite phones, satellite TV reception, as well as installations that are less familiar, eg VSAT stations and satellite broadcast TV stations. The term Earth station refers to the collection of equipment that is needed to perform communications via satellite: the antenna (often a dish) and the associated equipment (receiver/decoder, transmitter). repeaters: repeaters accept all the modulated R.F career in its uplink and amplifies back it to earth station in its down link
What planet has the sixth largest satellite in the solar system?
The sixth largest Satellite in the solar system is Europa, a moon of Jupiter.
What is the glonass?
GLONASS is a constellation of satellites with a similar purpose to the US GPS system with a minimum of 24 satellites. GLONASS is operated by the Russian Federation, and finally became fully operational in 1993 with the full complement of 24 satellites. China has a similar system underway, known as COMPASS, but it has only 10 satellites operational yet, and with the aim of 30 units. A mix of geostationary and low orbit elements. IRNSS (Indian regional navigation satellite system) is also underway, but with 2 geostationary orbiting satellites operational of 7 planned. GALILEO is the navigation system being constructed by the European Union, with 4 (out of 10) of the planned satellites operational. There is also a DORIS system operated by France, but this uses quite a different system. Information from this helps ascertain the elevation of the JASON 1 and JASON 2 systems to a few cm.
When was the first GPS satellite launched?
The first satellite in the system, Navstar 1, was launched February 22, 1978.
What is terrestrial system for satellite communication?
A terrestrial system for satellite communication is one that facilitates. This includes the facilitation of audio, data, and any other communication.
What has the author Chris Barret written?
Chris Barret has written: 'Flight control augmentation for AFT CG launch vehicles' 'Spacecraft flight control system design selection process for a geostationary communication satellite' -- subject(s): Control systems, Space vehicles, Torque
Why is geostationary important?
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). At this altitude, one orbit takes 24 hours, the same length of time as the earth requires to rotate once on its axis. The term geostationary comes from the fact that such a satellite appears nearly stationary in the sky as seen by a ground-based observer. In other words a satellite that orbits a specific part of the earth while the earth is rotating so it looks like the satellite doesn't move. For example if you put a satellite over over the geographic US it will stay over the US and turn with the earth around the axis without ever loosing site of the US.
What is the role of satellite in disaster management as a alternative communication system?
it tells us about the disaster before happening
What is the advantages and disadvantages of satellite telecommunication system?
1) The coverage area of a satellite greatly exceeds.2) Transmission cost of a satellite is independent of the distance from the center of the coverage area. 3) Satellite to satellite communication is very precise. 4) Higher bandwidths are available for use.
What are the QPSK applications?
1.CDMA System 2.cable modem 3.video conferencing 4.in satellite communication
Why are ground stations in continuous contact with satellites in geostationary orbit?
Just imagine managing a system of communication satellites which were non-geostationary. Data needs to be sent to one city, one home, but the satellite for the job is different every time. The task would be manageable, but unnecessarily difficult. Further more, metropolises must have priority over small towns- or oceans. New York needs more satellites than Apple Creek Ohio or the Atlantic Ocean. Finally, many satellites serve a very specific audience. Your favorite radio station would almost never come into reception if the satellite broadcasting it is circling the world.

Why do they make satellites?
Earth satellites are used for three general purposes. The first is to study the environment of space around Earth, and for astronomical observations. The second is to study Earth from the vantage point of space, as with geology, weather, and military uses. The third is to support communication, including telephones, television, and data relay without the need for interconnecting landlines. An example of the first use is the Hubble telescope. For the second use, we have dozens of spy satellites and the GOES weather observation system. For the third, satellite phones allow communication from virtually anywhere on the globe. And, with the proper technology, information can be retrieved through one of the many geostationary satellite systems.
Why microwave frequency are used in satellite communication?
Microwave is a "line of sight" system, so the two points must be able to "see" each other. If they're linked by satilite, that can be around the world, and if by microwave towers then as far as you can see the tower.
When was The System - satellite radio - created?
The System - satellite radio - was created in 1999.
