Satellite Communication | Ahmed Daud –
Log In Sign Up. Such objects are sometimes called artificial satellites to distinguish them from natural satellite such as the moon. Since then, thousands of satellites have been launched into orbit around the earth. Satellite communications play a vital role in the global telecommunications system.
Fundamentals of Satellite Communication
Approximately 2, artificial satellites orbiting Earth relay analog and digital signals carrying voice, video, and data to and from one or many locations worldwide. The Problem of Space Travel: The Rocket Motor Arthur C. Clarke — 19 March Postulated the entire concept of international satellite telecommunications from geostationary satellite orbit including coverage, power, services, solar eclipse.
This satellite broadcast satellitf taped message: Explorer 08 April 12, It carried a payload of 80 pounds of sodium and soared to about km into the atmosphere.
It failed to achieve orbit.
Communications satellites have been a significant part of domestic and global communications since the s. Typically they move l.n.raja geosynchronous orbits about 22, mi 35, km above the earth and operate at frequencies near 4 communicatino GHz for downlinking and 6 GHz for up linking. A Earth Station sends message in GHz range. Satellite Receive and retransmit signals back. Other Earth Stations receive message in useful strength area.
Indicated are the short-hand letter designations along with an explanation of typical applications. When is satellite the best solution? Whether crossing continents or staying local, satellite connection cost is distance insensitive.
Global Availability – Communications satellites cover all land masses and there is growing capacity to serve maritime and even aeronautical markets.
Customers in rural and remote regions around the world who cannot obtain fuhdamentals speed Internet access from a terrestrial provider are increasingly relying on satellite communications.
Superior Reliability – Satellite communications can operate independently from terrestrial infrastructure. When terrestrial outages occur from man-made and natural events, satellite connections remain operational.
Superior Performance – Satellite is unmatched for coommunication applications like television.
For two-way IP networks, the speed, uniformity and end-to-end control of today’s advanced satellite solutions are resulting in greater use of satellite by corporations, rak and consumers.
Immediacy and Scalability – Additional receive sites, or nodes on a network, can readily be satllite, sometimes within hours. All it takes is ground-based equipment.
Satellite has proven its value as a provider of “instant infrastructure” for commercial, government and emergency relief communications. Versatility and More – Satellites effectively support on a global basis all forms of communications ranging from simple point-of-sale validation to bandwidth intensive multimedia applications.
Satellite solutions are highly flexible and can operate independently or as part of a larger network. Because the satellite is 36,km from the earth there is an appreciable funvamentals around 0. Internet and make conversation difficult in voice circuits. Satellites are large and expensive, thus there raao a large capital cost in building and launching a satellite; this means that you have to be able to get a lot of customers or support many services before launching a satellite, to be sure that the costs will pay back.
Impossibility to repair and maintain: It’s not possible to get a k.nr.aja person out to the GSO, so if components fail they can’t be fixed; satellites are made from “space qualified” components with high reliability but redundant components also have to be flown and byy in if elements do fail; a major failure can result in the loss of the whole satellite.
This satellite now enables extending of communication services to all areas of Pakistan. Fiber optics communication is quicker but satellite is slow in communication.
Fiber Optics communication higher bandwidth but Satellite Lower Bandwidth. In case of any fault we can easily repair Fiber Optics but Satellite can not be repair. Fiber Optics initial Cast fnudamentals low but Satellite is very High.
Many People want to communication during jogging, driving, sailing and flying these all possible in Satellite Communication But Fiber Optics not use for them.
Satellite Communication : Concepts and Applications
Fiber Optics is Very costly for long range communication but Satellite is low for long range communication. Future communication satellites will have more onboard processing capabilities, more power, and larger-aperture antennas that will enable satellites to handle more bandwidth.
In addition, other technical innovations such as low-cost reusable launch vehicles are in development. With increasing video, voice, and data traffic requiring larger amounts of bandwidth, there is no dearth of emerging applications that will drive demand for the satellite services in the years to come. The demand for more bandwidth, coupled with the continuing innovation and development of satellite technology, will ensure the long-term viability of the commercial satellite industry well into the 21st century.
The use of laser communication is also under discussion. Elbert How Do Satellites Work? By William Cook, http: Remember me on this computer.
