artificial satellite, object constructed by humans and placed in orbit around the earth or other celestial body (see also space probe).The satellite is lifted from the earth's surface by a rocket and, once placed in orbit, maintains its motion without further rocket propulsion. The first artificial satellite, Sputnik I, was launched on Oct. 4, , by the USSR; a test payload of a radio. MICROWAVE ANTENNA SYSTEMS Microwave Antenna Systems Antennas with waveguide installation Small antennas (1 and 2 ft) operating in the frequency range above 10 GHz are, as a rule, connected directly to the transmission equipment. Special mechanical and electrical matching ensures that the RF signal passes directly into the radioFile Size: 2MB.

The time delay is a function of various parameters and is given by: where, R = radius of the earth h = orbital altitude θ= satellite elevation angle c = speed of File Size: KB.   The 34th AIAA International Communications Satellite Systems Conference (ICSSC) and the 22nd Ka and Broadband Communications Conference, the two most influential technical conferences on communications satellite systems, will be held jointly in Cleveland, Ohio, October 18 to 20, is the year in which the AIAA ICSSC will celebrate its 50th anniversary and this [ ].

  – Sputnik and the Space Race. The famous Sputnik was the first artificial satellite to be launched into space. The satellite was launched into a low-earth orbit by the Soviet Union on 4 October A low-earth orbit has an altitude of km. Sputnik carried four external radio transmitters, and their pulses were detectable. The launch of Sputnik was a very significant Author: Umair Hussaini. Satellite Network Segments. Satellite networks have three major segments: Space segment—The space segment is the actual design of the satellite and the orbit in which it satellites have one of two designs: a barrel-shaped satellite, normally used to accommodate standard communications, or a satellite with a very wide wingspan, generally used for television.

I read this book as a reference rather than a formal class textbook. As a self-studying student, the first book I bought to study satellite communications was the famouns 'Digital Satellite Communications' ritten by Dr. Tri t. It is actually a quite good book. However it was just too much for a eginner.

satellite communication systems. These complications include the following: High Latency – The most common satellites used for the delivery of fixed broadband services, geostationary satellites, are located more t miles above the equator.

Because of this. These books are used by the students to get a good fundamental knowledge. 1. “Satellite Communication” by D.C. Agrawal and A. K.
