Patrick Sheridan is experiencing technical difficulties... Patrick's thrilled to become a student reporter on a teen news show. But when he leaves his small Texas town for the bright lights of Los Angeles, everything changes. It doesn't take long before Patrick is mingling with the rich and famous and doing all kinds of things he never thought he would -- like cheating on his girlfriend, lying to his parents, and losing his best friend. And by the time he learns that it was his handsome face and not his writing that landed him his new job, he's left to pick up the pieces alone. Hollywood is already full of beautiful people with no talent; how can he prove that he's more? He'll have to start by convincing himself.

An accessible introduction to the practical aspects of satellite communications. Provides historical background of satellite communications and discusses the wide range of applications throughout the world. Includes descriptions of all the commercial satellite communications systems currently available and their applications in government, broadcasting, and business. Also covers the growing use of satellite communications by developing countries. Contains extensive appendices listing satellite equipment and organizations.

Pt. 1 discusses feasibility of joint military-civilian use of COMSAT global satellite system.

Satellites are increasingly used for global communications, as well as for radio and television transmissions. With the growth of mobile communications, and of digital technology, the use of satellite systems is set to expand substantially and already all students of electronics or communications engineering must study the subject.This book steers a middle path between offering a basic understanding of the process of communication by satellite and the methodology used; and the extensive mathematical analysis normally adopted in similar texts. It presents the basic concepts, using as much mathematical content as is necessary to make the process understandable. The principles introduced are backed up by examples of actual applications showing how professional systems engineers have achieved the required system performance capabilities. The practical systems chosen are representative of modern day applications and comprise an international communications system, an international maritime system and a regional system.

Extensive revision of the best-selling text on satellite communications — includes new chapters on cubesats, NGSO satellite systems, and Internet access by satellite There have been many changes in the thirty three years since the first edition of Satellite Communications was published. There has been a complete transition from analog to digital communication systems, withanalog techniques replaced by digital modulation and digital signal processing. While distribution of television programming remains the largest sector of commercial satellite communications, low earth orbit constellations of satellites for Internet access are set to challenge that dominance. In the third edition, chapters one through three cover topics that are specific to satellites, including orbits, launchers, and spacecraft. Chapters four through seven cover the principles of digital communication systems, radio frequency communications, digital modulation and multiple access techniques, and propagation in the earth’s atmosphere, topics that are common to all radio communication systems. Chapters eight through twelve cover applications that include non-geostationary satellite systems, low throughput systems, direct broadcast satellite television, Internet access by satellite, and global navigation satellite systems. The chapter on Internet access by satellite is new to the third edition, and each of the chapters has been extensively revised to include the many changes in the field since the publication of the second edition in 2003. Two appendices have been added that cover digital transmission of analog signals, and antennas. An invaluable resource for students and professionals alike, this book: Focuses on the fundamental theory of satellite communications Explains the underlying principles and essential mathematics required to understand the physics and engineering of satellite communications Discusses the expansion of satellite communication systems in areas such as direct-broadcast satellite TV, GPS, and internet access Introduces the rapidly advancing field of small satellites, referred to as SmallSats or CubeSats Provides relevant practice problems based on real-world satellite systems Satellite Communications is required reading for undergraduate and postgraduate students in satellite communications courses and an authoritative reference for engineers working in communications, systems and networks, and satellite operations and management.

Among the space activities of the last three decades satellite communications (SATCOM) has found the widest application in meeting both civil and military communications requirements. Several international, regional and national SATCOM systems of increasing capacity, capability and complexity have been and are being implemented over the years. The latest versions are utilizing such concepts as spot beams, processing transponders in SS-TDMA and operations in different frequency bands including the EHF band. On the military side, the United States of America, the United Kingdom, France and NATO (the North Atlantic Treaty Organisation) have been the only owners and operators of military SATCOM systems in the West. The systems in being and under development use satellites and ground terminals with characteristics which differ from the civilian ones with respect to frequency bands utilised and survivability and interoperability. The SATCOM has given the military users the potential of having much-needed mobility, flexibility and survivability in strategic and tactical communications for land, sea and air operations. It must, however, be said particularly for the military SATCOM systems that they have been evolved in big jumps, both in time and capability, each jump involving the deployment of two or three often specially designed large satellites, large expenses and rather traumatic transition between jumps. Despite these undesirable features these systems did not have the required degree of suevivability and flexibility.

Cole Haufner has no equal as a professional MMA fighter. At the peak of his success, Cole suffers a horrible personal tragedy. His grief deepens when his brother, Butch, a Delta Force operator, goes missing. Desperate to find Butch, Cole travels back to his childhood home in southeastern China and the Shaolin Temple where he was raised. When Cole meets his brother's Delta teammate, code name Hammer, his fame and personal agenda collide with the Delta unit's mission to recover an invention that could transform the human race. It could also see its downfall, if the pursuing North Korean agents find it first. Cole's spiral downward approaches madness as a family secret is revealed, one that could force him to choose between his brother and one of the most important, and potentially deadliest, discoveries in modern human history.

This work addresses the whole range of problems relating to the application of satellite technology to studies of regional seas and sea phenomona - the Gulf Stream, the Kuroshia Current - and coastal zones. It argues that to emphasize global applications is to fail to take into account fundamental idiosyncracies specific to the regional perspective. In addition, it describes implementation techniques - data gathering; in situ data assurance, algorithms for parameter retrieval; data storage; and data output.; The book contains satellite imagery and incorporates case studies from areas such as the Baltic and the Black Sea.
