Global Positioning System (Gps) Research Paper

The human race(a) Positioning SystemWith the proliferation of satellite-based falsifying systems and their continuing battlefront in the media it begets us more(prenominal) than aware of our bailiwick defense. The United States is large, economically strong and a sometimes tumultuous presence in the global community. Although we may feel secure because of our superior engine room and defense capabilities, our size and position in world affairs stop make us a target for some countries. We set up no longer be concerned with just our borders and without delay what comes from the skies and the sea is more of a threat than ever before.The United States government had to bristle a way to counter these possible attacks and the globular Positioning System (GPS) was conceived. The Global Positioning System was initiated in 1973 by the Department of Defense (DOD). It was highly-developed by the the DOD because at a cost of over dozen billion dollars the government had the monetary resources to achieve these idealistic goals. Since that time it has bighearted from one satellite employ strictly by the military to twenty-six satellites that can be used by civilians also.This satellite system is used to determine the speed and position of an object anywhere in the world within one hundred meters to mere millimeters dep deceaseing on the size and fibre of user equipment. (GPS JOINT PROGRAM OFFICE. ICD-GPS-200GPS INTERFACE CONTROL DOCUMENT. ) The original use of GPS was to maintain a strategic military advantage over our enemies. Toward the end of the arms race the targeting of ballistic missiles became so exact they could land at once on an enemy missile silo and destroy any missiles inside of it. The index to take out your enemies missiles from great distances had a major effect on the balance of power.To maintain the balance of power the United States government had to develop a way to locate surfacing submarines in a study of minutes anywhere in the wo rld. With the use of satellites in orbit the Global Positioning System was created. GPS uses twenty-six satellites and ground tracking stations roughly the world to compute distances using time. This is done by finding the deflection between the time a signal is sent and the time it is drived. The satellites imbibe atomic clocks so the time is extremely accurate. The receivers position is fit(p) by using leash satellites, this is called triangulation. (kAPLAN,eLLIOTT.UNDERSTANDING GPSPRINCPLES AND APPLICATIONS) GPS is made up of three segments space, fit and user. The space segment complicates the satellites and the rockets that launch them from Cape Canaveral. The satellites are provide by solar cells and continuously point theirsolar panelstoward the sun and their antennae toward earth. The control segment includes the master control station in Colorado and superintend stations around the world. This segment makes sure orbits and clocks operate within acceptable limits. The user segment includes the equipment used by the military and civilians who receive GPS signals. Kaplan, Elliott. UNDERSTANDING GPSPRINCIPLES AND APPLICATIONS) The military applications of GPS are used in fighters, bombers, helicopters, submarines and spends gear. Wartime defense is now more accurate and dependable than ever. While still the most big aspect of this engineering, GPS is not used strictly for navigation anymore. different uses include but are not limited to target designation, air support, soldier rendezvous and smart weapons. Smart bombs use GPS to receive location breeding so they can guide themselves to a preset target.This technology is a great asset in battle as it basically casts a net over a battlefield and can locate tanks, vehicles or even soldiers who may be in immediate danger. In the common world, GPS has also made life easier and safer. Hikers and hunters can carry hand held receivers in case they should get lost in the wilderness. On-board navi de stinations through voice-activated user equipment. Drivers can also make cellular calls using these GPS computers should something happen to them in transit. Other aspects of this technology are used in farming.Maps can be created of the field during harvest and used the next season to plant and fertilize areas that neediness more attention. This increases crop production while reducing the use and depreciate of fertilizers, pesticides and fuel which also helps our environment. This process is called Precision Farming. Another very all important(predicate) use of GPS is the avoidance of in-flight collisions. Airlines are in the process of equipping their airplanes with GPS receivers. This impart enable each aircraft to detect other planes in the vicinity and make sure they dont cross paths in the air.This is much more accurate and rock-steady system than is currently available and is sure to make the people ephemeral in these planes more comfortable and secure. The Global Posit ioning System has giving into a resource that goes far beyond the initial design goals. These years scientists, farmers, soldiers, pilots and delivery drivers are using GPS in ways that make their jobs safer and more productive. The benefits of GPS are not limited to job related aspects alone. The future of this technology is limitless and will change and develop rapidly as upstart and varied applications are introduced.
