Advantages And Disadvantages Of Satellite Communication

This example focuses on the use of satellite networking, to broadcast the signal from the satellite, to the ground station. This type of technology involves the use of Zigbee at small distances, and WiMax for greater distances.

During the Space Race, the first orbital satellites were sent to outer space. Today, Americans can communicate, predict the weather, and study geodetics because of the satellites that first orbited in space.All satellites and space probes carry specialized radios receiving and transmitting equipment for guidance and control purposes as well as relaying data from space to Earth. Without the first satellite transmission of a human voice in 1958, communication would not be as efficient (Rabinowitch, 1963).

An example of this is the satellite television which was introduced in 1962 with the launch of the Telstar satellite. With this, television signals were able to travel through space to televisions around the world. Another invention that was introduced during this time was the weather satellite. “Kennedy also requested funding to accelerate the use of communication satellites to expand worldwide communications and the use of satellites for worldwide weather observation. Both of these initiatives quickly evolved into major areas of space technology that now serve the global community” (Angelo 29).

“Even before the first satellite was launched, U.S. leaders recognized that the ability to observe military activities around the world from space would be an asset to national security… Intelligence-gathering satellites have been used to verify arms-control agreements, provide warnings of military threats, and identify targets during military operations, among other uses” (Space Exploration). During an age when nuclear threats loomed upon both the U.S. and the USSR with frightening reality, it was crucial for intelligence agencies of both nations to gather as much information as possible about the other’s missile programs and operations. This created the demand for orbiting satellites that would send back crucial information. Another benefit of orbital satellite reconnaissance was the low risk involved. In 1960, an American U-2 spy plane flying over the Soviet Union on a reconnaissance mission was shot down by the Soviets. “The Soviets managed to shoot down Powers's U-2 and capture the American pilot” (U-2 Affair). The pilot was imprisoned, CIA operations were revealed, and the U.S. was under a huge international embarrassment. Launching satellites does not risk losing human lives, leaking secret information, or losing national integrity during unexpected occasions such as the U-2

It has the leading role in the military exploration of space and uses aircraft and satellites to collect photo, video, and signal intelligence.

The selection of satellites bands with wider frequencies allows a variety of information to travel and decreases the limitation of usage by the users. The Ka-Band (26-40GHz) the communication satellites provides high resolution, close ranges targeting radar on military crafts(TIA,2013). The current suggestion of band would be the Ka-Band (26-40GHz) the communication satellites allows high resolution, close ranges that support strong military functions(TIA,2013). advancements to the developing concept, identify leverage over the other choices, utilizing Ka-bands do propose substantiated risks however, it is still operable (Lewis, 2014). Users offering themselves a band with wider frequency means information can transfer swiftly whereas, a smaller frequency could offer more accuracy but limits the user capability. All forums offer positive attribute and consequential attributes but overall the assessment has to be made by the operation leader. As technology develops engineers are developing ideal that are properly modified to support the needs of the community and excel in

The United States of America relies heavily on its ability to operate in the most contested and most undetermined domain, space. The space domain is one of the newest domains that the United States finds itself contending in, desperate to combat the unknown or unforeseen. The battle ground is the contentious and hugely unknown areas that float above the heavens. The soldiers the best and brightest engineers and physicists that the world has ever known. The front lines are the exponentially long math equations that produce precise launch equations that place objects in orbit around our Earth. Those objects are satellites and their functions are as numerous as the varieties of their uses multiplied by the nations that own them. They control everything from the precise time that is printed on your Starbucks receipt to the exact location that a Tomahawk cruise missile destroys its target. Space based technology is interwoven throughout our government, the military, the U.S. economy, but it’s also provides a level of peace and security to the American people. Even though the Outer Space Treaty of 1967 strictly prohibits the militarization of space, the U.S. Department of Defense has a strategic obligation to protect the U.S. Space Program from its near peer adversaries because of the impacts on the global economy and to the security of United States citizens.

There is no doubt that technology has affected the path of communication, interaction and human relationships. A large number of communication devices like phone have been invented in order to help communication between people. Thus, by giving easier chance to be connected, this development has been encouraging society’s sense of togetherness. Advances in technology have brought people closer with the use of different communication gadgets or websites. On the other hand, it has reduced the real-world or physical interaction. Technology has both pros and cons. But, sometimes the more positive roles overshadow the negative points. Ultimately, technology has improved the communication and relationships between people.

If we were to launch a space mission, the first step would be, well, building a spacecraft. Since Sputnik launch in 1957 until recently, the satellite industry was limited to governmental labs, military and telecommunication companies. Costing from hundreds of millions up to billions

Due to the existing ground segment are based on technology from 1980s, the difficulty and the cost for maintenance and operation of the ground segment were getting higher. Thus, the Space Network Ground Segment Sustainment (SGSS) Project was derived in March 2008 Space Network modernization concept Study and started the formulation on November 2011. The SGSS project was aim to reduce the life cycle cost of ground segment operations and maintenance, as well as to continue safe and reliable operations for the next

Jim Sciutto conducted a 1-hr documentary on the inevitable war in space. Sciutto interviewed more than ten national security, defense and high-ranking military personnel to include the entire chain of command for space warfare. Sciutto explains that American (citizens, military, and government) depends on our satellites every day. However, our adversaries are targeting America's satellites and are preparing to disarm America from her satellites usage with weapon systems such as lasers, kamikaze satellites, and even kidnapper satellites.

On October 7, 1957, the Space Age had officially began. The USSR sent a satellite, ‘Sputnik’, into orbit around Earth(History.com-soviet union launches sputnik). The journey lasted less than 100 minutes, but it was a landmark occasion nonetheless and the Soviet Union had sent a message to the capitalist world. On the satellite ‘Sputnik’ was a radio transmitter which allowed Soviet scientists to track it as it orbited the Earth. This signal

With one click of a button, technology has allowed the world to communicate with people several thousand miles away in just a few seconds. Advancements in technology have a positive impact on the way people live around the world; the innovations and integrations of technology has allowed almost anyone to do almost anything. The world has become extremely dependent on technology, which creates a high demand for advancements that positively change the way of living, especially the way of communication, for everyone. Globalization and connectivity through technology has allowed for friends and family to visually communicate with each other through video-calling programs, the conducting of businesses internationally, and for medical assistance around the world.

Since the beginning of the industrial revolution, the world has become a smaller place. The time used to travel to far distances has diminished; with the growth of new technologies, traveling and communicating have become simple daily tasks for many people. Through the growth of global communication, people have become closer to others across the globe, and business has gone world wide. One invention that came along with the technological revolution is the cell phone. Cell phones allow us to be reachable anywhere at anytime, letting us communicate even during travel. As time becomes more valuable for people, the importance of accessibility to communication also increases. With cell phones, the communication and

Space exploration refers to the exploration and discovery of outer space’s celestial structures by means of the ever-growing space technology, which is continuously evolving. Space physical exploration is conducted by using unmanned robotic probes. Human spaceflight is also used for space exploration. The history of space exploration dates back to the 20th century when the world’ most powerful states such as Russia and the United states scrambled for superiority. Space exploration therefore became a sense of pride and extreme manpower leading to development of space vehicles, which attempted to reach space. The space exploration programs were conducted by government space agencies mainly of the United States and Soviet Union due to the sensitivity and huge finances involved. With time, private organizations began to purchase and offer space launches, laying ground for private space flight. Satellite radio, communications satellites, astronaut transport, satellite television and sub-orbital space tourism comprise the Earth orbit’s private space lift.
