  • In keeping with the objectives of the previous editions, the third edition is intended to provide broad coverage of satellite communications systems, while maintaining sufficient depth to lay the foundations for more advanced studies. Mathematics is used as a tool to illustrate physical situations and obtain quantitative results, but lengthy mathematical derivations are avoided. Numerical problems and examples can be worked out using a good calculator or any of the excellent mathematical computer packages readily available.

  • This report presents the results of a theoretical analysis of a frequency-hopping, multiple-frequency-shift-keyed, spread-spectrum communication system using a nonprocessing communication satellite transponder. A large number of users are assumed to be hopping pseudo-randomly about the transponder passband in time synchronization and approximate frequency synchronization. The users are assumed to ......

  • Satellites and viroids have features which differentiate them from the bet- ter understood conventional viruses. However, they have features which are common to several viruses and they are often referred to as subviral agents. The similarities with conventional viruses have permit- ted a preliminary classification of viroids into families and genera. Invite you to refer to the document "Satellites, viroids and prions" content more learning materials and research.

  • Research objectives: Collect and process the magnetic data from CHAMP satellite and from the magnetic observatories within 6 years (from 2002-2007); study the method to separate magnetic field caused by EEJ from the observed data; identify some parameters of EEJ in all over meridians and study the variation of EEJ in space and time. The variation of EEJ in longitude, latitude and local time.

  • The last decade proved to be hugely successful for the mobile communications industry, characterised by continued and rapid growth in demand, spurred on by new technological advances and innovative marketing techniques. Of course, when we refer to mobile communications, we tend to implicitly refer to cellular systems, such as GSM. The plight of the mobile-satellite industry over the last decade, although eventful, has, at times, been more akin to an out of control roller coaster ride.

  • A valve amplifier or tube amplifier is a type of electronic amplifier that makes use of vacuum tubes to increase the amplitude of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s. Valve amplifiers are used for applications such as guitar amplifiers, satellite transponders such as DirecTV and GPS, audiophile stereo amplifiers, military applications (such as radar) and very high power radio and UHF television transmitters....

  • Satellite altimetry was developed in the 1960s soon after the flight of artificial satellites became a reality. From the vantage point in space, a radar altimeter is able to measure the shape of the sea surface globally and frequently. Such measurements have a wide range of applications to oceanography, geodesy, and geophysics. The results are often revolutionary. For example, in oceanography; it takes a ship weeks or months to cross the ocean making measurements while the ocean is constantly changing its circulation, temperature, and salinity.

  • The use of satellites in communications systems is very much a fact of everyday life, as is evidenced by the many homes equipped with antennas, or dishes used for reception of satellite television. What may not be so well known is that satellites form an essential part of telecommunication systems worldwide, carrying large amounts of data and telephone traffic in addition to the television signals.
