Abstract- In this paper we discussed satellite and radio communication links. Satellites have evolutionized communication. Satellite and radio communication has served mankind in many ways for instance it is used to predict weather and broadcast storm warnings and also provides a wide range of communication. Here satellite and radio communication recent technical advances, role in various fields and there applications are discussed. And various term related to communication such as geosynchronous orbit, Software Defined radio (SDR) etc.
Key Words: Advanced Communication Technology satellite (ACTS), Geosynchronous Orbit (GO), National Aeronautics and Space Administration (NASA)

INTRODUCON

In this present era, communication plays a vital role. We use a wide range of devices to communicate between two persons placed at different places (irrespective of the distance between them). Any earth-orbiting spacecraft that provides communication over long distances by reflecting or relaying radio-frequency signals. Satellites have evolutionized communication by making worldwide Telephone links and live broadcasts co mmo n occurrences. A satellite receives a microwave signal from a ground station on the earth (the uplink), then amplifies and retransmits the signal back to a receiving. The Satellite itself is also known as the space segment, and is composed of three separate units, namely the fuel system, the satellite and telemetry controls, and the transponder. Radio is the transmission of signals by modulation of electromagnetic waves with frequencies

    Communication satellites work non-stop 24 hours a day to keep the entire world linked together. Until recently NASA had been the only one's launching satellites, but now many private companies are benefiting from what a satellite can do. Once a satellite becomes geosynchronous, rotates with the earth orbit, a satellite is ready to work. It then beams messages to a ground station, the ground station receives these messages by using a device called a transponder. Which interrupts the message and then distributes it. By doing this satellite stations can than transport telephone service, data, or television transmissions to almost anywhere. These communication satellites are used for things like an overseas phone call or beaming 150 channels into your living room.…

    In 1945 Arthur C. Clarke wrote an article entitled "The Future of World Communications" for the magazine Wireless World. This article, which the editors renamed "Extra-Terrestrial Relays", was published in the October issue. In it Clarke described the properties of the geostationary orbit, a circular orbit in the equatorial plane of the earth such that a satellite appears to hover over a fixed point on the equator. The period of revolution is equal to the period of rotation of the earth with respect to the stars, or 23 hours 56 minutes 4.1 seconds, and thus by Kepler's third law the orbital radius is 42,164 km. Taking into account the radius of the earth, the height of a satellite above the equator is 35,786 km.…

    The colossal benefits of space travel to date are boundless, the discovery alone of how gravity can keep objects in orbit around the earth without the use of thrusters has revolutionised how the human race interacts through orbiting satellites. Satellites stay in orbit by gaining enough velocity with the right altitude to reach orbital velocity (the minimum velocity at which a body must move to maintain a given orbit.)1 The lower an orbiting satellite is the quicker it needs to travel to avoid orbital decay (the proses of rapid decreasing in altitude)2.…

    The prime purpose of radio is to convey information from one place to another through the intervening media (i.e., air, space, nonconducting materials) without wires. Besides being used for transmitting sound and television signals, radio is used for the transmission of data in coded form. In the form of radar it is used also for sending out signals and picking up their reflections from objects in their path. Long-range radio signals enable astronauts to communicate with the earth from the moon and carry information from space probes as they travel to distant planets (see space exploration). For navigation of ships and aircraft the radio range, radio compass (or direction finder), and radio time signals are widely used. Radio signals sent from global…

    • 1832 Words
    • 8 Pages

    Running Head: Satellite Radio Introduction Satellite radio is a more advanced substitute to terrestrial-based services. The choice of capturing radio frequencies via satellite involvement allows access to a mobile radio service. Satellite radio functions with the help of fixed-location receivers, dish antennas and signal repeaters. These commercial investments permit the listeners to enjoy hands-free communication over immense geographical areas. It provides coverage around tall buildings and bridges, in any weather, without the slightest interruption unlike terrestrial. The dish antennas and signal repeaters are invested in and set-up by the providers of the technology, to make signals or frequencies more available to listeners within a set range. Background Digital Audio Radio Service (DARS) was launched by the Federal Communications Commission (FCC) in 1992 by creating specific segments of radio frequency for satellite broadcast on radio. An auction was later held for the buying of these particular radio frequencies and two companies…

    In this 21 century communication is our basic requirement. Some time we are in an area where Wi-fi, GSM and other terrestrial communication are not available so we are no able to communicate or send messages to others. Without any terrestrial connectivity we are not able to install any project that is required one way or two way connectivity. In this situation satellite communication device comes to help us. So we can us to send or receive data using satellites for our projects like Oil pipelines, Weather data, Location tracking and Emergency communication etc.…

    Contextual Outline Humans are social animals and have successfully communicated through the spoken word, and then, as the use of written codes developed, through increasingly sophisticated graphic symbols. The use of a hard copy medium to transfer information in coded form meant that communication was able to cross greater distances with improved accuracy of information transfer. A messenger was required to carry the information in hard copy form and this carrier could have been a vehicle or person. There was, however, still a time limit and several days were needed to get hard copy information from one side of the world to the other. The discovery of electricity and then the electromagnetic spectrum has led to the rapid increase in the number of communication devices throughout the twentieth century. The carrier of the information is no longer a vehicle or person — rather, an increasing range of energy waves is used to transfer the message. The delay in relaying signals around the world is determined only by the speed of the wave, and the speed and efficiency of the coding and decoding devices at the departure and arrival points of the message. The time between sending and receiving messages through telecommunications networks is measured in fractions of a second allowing almost instantaneous delivery of messages, in spoken and coded forms, around the world. This module increases students’ understanding of the nature, practice, application and uses of physics and current issues, research and developments in physics.…

    History of Dth

    • 2952 Words
    • 12 Pages

    The entire satellite communications industry -- not just the DTH segment -- can trace its common heritage to one man. That man is the noted futurist and author Arthur C. Clark. Long before Clark was to take us to the farthest reaches of the universe in his legendary epic "2001: A Space Odyssey," he penned a paper entitled, "Extraterrestrial Relays." Published in October 1945 by "Wireless World Magazine," this article advanced a theory that world-wide communications could be accomplished by placing three space platforms into special orbits 22,300 miles above the equator. Clark explained that at this altitude, the platforms would orbit the earth at exactly the same speed as the earth turned -- thus they would appear to remain motionless in space when viewed from the ground.…
