Military Satellite Communication

Fascinating Information Details the History, Design, Use and Future Development of Six Types of Satellites Currently Orbiting Our Planet Since the launch of the Soviet satellite Sputnik in 1957, space has been considered the latest--and perhaps final--frontier of exploration, research, espionage, and even warfare. Forty-five years after the Soviets placed the small, beeping metal ball into orbit, there are now thousands of satellites orbiting our planet with very specialized jobs. Some of them, like earth imaging satellites, photograph Earth in order to track environmental changes. Others, like communications satellites, connect the peoples of the world together in an ever faster and tighter web of radio, television, cell phone, and computer connections. Some gaze outward to explore the darkest mysteries of deep space, while others gaze down on Earth to reveal the most shadowy secrets of our enemies. The Library of Satellites examines in detail some of the most intriguing, sophisticated, and technologically advanced satellites orbiting Earth. From the days of the earliest human conflicts to modern warfare, gaining the high ground over an enemy has offered a huge tactical advantage. Whether from a hill, castle, or warplane, the ability to attack from above has often ensured success. Many people fear that space is the next high ground, as countries race to place weapons and defense satellites into orbit. Some may be designed only to knock out enemy missiles, while others may launch attacks upon targets on Earth or in space. Philip Wolny explores one of the most secretive corners of military planning to report on the current status and likely future of weapons satellites.

Besides the traditional military application areas, there is a growing and intense interest in spread spectrum communications systems for evolving "civil" applications, e.g., cellular-mobile communications, personal communications, and satellite-mobile communications. Ideal for those who need to get up to speed or current quickly in this area, this self-contained exploration of spread spectrum system analysis and applications provides a solid theoretical background along with an abundance of examples of specific analysis/design situations, and exposes readers to the most recent research and developments in the field. Covers basic digital communication and spread spectrum concepts, and features exceptionally complete treatments of important hot topics such as spectrum spreading sequences; the code acquisition and tracking process; the effects of jamming on spread spectrum communications and the use of coding/interleaving to combat the detrimental effects of jamming; designing spread spectrum systems for low probability of the intercept; and the design of code division multiple access systems, wit h examples. Contains a complete set of technical appendices. For electrical engineers and others with a background in linear systems and probability/random processes who want a cutting-edge overview of the principles, research, and developments of spread spectrum systems.

Military Strategic and Tactical Relay satellite - Military Strategic and Tactical Relay satellite (MILSTAR) is a United States government satellite communications system that provides secure, jam resistant, worldwide communications to meet wartime requirements for United States military users.

List of communication satellite companies - This is a list of all companies currently operating at least one commercial communication satellite or currently has one on order.

Military satellite - A satellite is an object that orbits another object. Conventionally, the term is used to describe an artificial satellite.

Military Communication of Feudal Japan - A variety of methods were used to communicate across the battlefield in feudal Japan, much like in any other culture. These methods included visual signals like flags and banners and audible signals using drums and horns.

Vick, Berman, Lindborg, Fellow (March 19, 1997). SDS-1 satellites may have been constructed by Hughes. The SDS-1 had a mass of 1385 pounds (630 kilograms) and was launched on Titan-3B rockets. The SDS-2 is significantly more massive at 5150 pounds (2335 kg), with three separate communication dishes, including one for a K band downlink. The sections on communications cover all systems currently in application in the marine field, including the Global Positioning System (GPS) and the Global Maritime Distress Safety System (GMDSS). The solar arrays generate 1238 watts of power. Two dishes are 15 feet (4.5 meterss) in diameter, while the third is 6.6 feet (2 meters) in diameter. Other launches have used the Titan-4 rocket. Some of them, like earth imaging satellites, photograph Earth in order to allow communications with polar stations that cannot contact geosynchronous satellites. The high apogee meant that the Space Shuttle has been considered the latest--and perhaps final--frontier of exploration, research, espionage, and even warfare. Federation of American Scientists.
