The history and the future of GPS - Research Paper ExampleAnother series of GPS button up III is under development process which would be able to give more powerful signals and better (PNT).The Global Positioning System provides information relate to time and location. It is a satellite sailplaning system which works well in all weather conditions on and close to the earth (Global Positioning System). It is possess and maintained by the United States of America and serves in the PNT i.e. positioning, navigation and timing. GPS has played vital role in modernizing the Air Traffic System and it has benefitted the military, army, civil and mercantile users all around the world. The whole system is basically divided into threesome major segments including Space segment, Control segment and User segment. The first two be developed and operated by the US Air Force (GPS overview).The position segment consists of a group of satellites which form a particular shape in the space and tr ansmit radio signals to the users. At least 24 satellites are available in the space 95% of the time (Space segment). The control segment represents all the fuze facilities that monitor the satellites, analyze their data and keep a check on their performance (control segment). The user segment is used to calculate the users three dimensional position and time by GPS receiver equipment which receives the information from the satellites and transmit it to the GPS receiver device (user segment).GPS was developed by the US Department of Defense (DoD) and started its trading operations in 1994. The previous navigation systems had some limitations and drawbacks which actually gave rise to the creation of GPS. The project was developed in 1973 by the unification of ideas from the previously working navigation systems (National Research Council U.S.). Originally it ran with 24 satellites.The first experimental GPS I satellite was launched in 1978 and by 1985 ten more satellites were
