Gps ( Global Positioning System)
Introduction The Global Positioning System (GPS) is a satellite-based steering system that comprises a set-up of 24 satellites placed into the path by the U.S. Defense forces. The Global Positioning System was projected initially for military applications, although in the 1980s, the government permitted civilian use of the system. Notably, GPS works in any environment, wherever in the world, 24 hours on a daily basis. There are no payments or setup charges to exploit GPS, as it is free of charge. The GPS program provides significant capabilities to martial, communal as well as commercial users all over the world. Additionally, GPS is the strength of character for modernizing the universal air traffic system. Changes in technology and recent demands in the current system have resulted to efforts to modernize the GPS system and come up with the new generation of GPS III satellites with Next Generation Operational Control System. This essay discusses the functions, advantages and disadvantages of Global Positioning System in detail.
Working of the Global Positioning System GPS satellites go round the earth twice a day in a fixed orbit and broadcast signal information to earth. GPS receivers obtain this information then utilize triangulation to gauge the user 's exact location. Fundamentally, the GPS receiver system contrasts the exact time a signal was transmitted by a satellite with the exact time it was received (Diggelen 55). The difference in time tells the GPS receiver how distant the satellite is. Now, with distance dimensions from additional satellites, the receiver is able to establish the user 's location and exhibit it on the unit 's electronic chart. A GPS receiver should be locked on to the signal of not less than three satellites to work out a 2D location (latitude and longitude) and path movement. With at least four or additional satellites in view, the receiver can resolve the user 's 3D location (altitude, longitude and latitude). Once
