"Never worry about going lost again, GPS would help you get back up and going"
GPS stands for Global Positioning System. This system is used to locate an exact location based on the real-world mapping system with latitudes and longitudes. A GPS system functions through the help of a satellite, that broadcasts the fastest microwave signals to and from the GPS devices and their corresponding earth’s surface real-time details. GPS system is monitored and operated by the Department of Defense of the USA, for the proper use by the military and the regular mass of people.
The GPS signal includes several range estimating signals that measures the distance of the satellite from the earth’s surface, along with some navigational messages. These navigational messages are very helpful in calculating the position of the satellites around the orbit and various information’s related to the time and status of the complete satellite distribution in the outer atmospheric level.
These GPS satellites transmits several codes simultaneously, but only a limited number of centralized frequencies are used, using the Code Division Multiple Access. The ranging codes transmitted by the satellite are known as chipping codes, these are in the form of pseudorandom binary sequence. These satellites are identified by the Space Vehicle Number, which uniquely distinguishes them in the space.
The GPS coding design contains mainly three types of ranging codes –
1) Coarse – These codes are of 1,023 chips in length and are transmitted at the speed of 1.023 Mbit/sec and are used by both the military and the civilian masses.
2) Acquisition – These codes are of 1,023 chips in length and are transmitted at the speed of 10.23 Mbit/sec and are also used by both the military and the civilian masses.
3) Precision – These codes are restricted to use only by the military personals and the exact details are not been released publicly.
These devices serves in a whole range of developments and non-developments sectors by providing the coordinates of every non-restricted locations on this planet, without much of worry and saves a lot of time that would have been needed for manual calculations.
The GPS devices are also available in almost every modern smartphone that can help you to know your surrounding environments better, and could seriously help you out if you are mistakenly lost in any unknown place or if you need any kind of SOS help at your location.
