Nowadays Technology is rapidly developing; these developments are made in order to make life easier for humans. Two project globally used and recognized are referred to as Global Positioning System (GPS) and Embedded Web Technology (EWT).
GPS was originally used and made for military applications in the 1980's. The GPS is a navigation system based on satellites. It is said to be made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense.
GPS satellites move around the earth twice a day in a very precise and measured orbit; transmitting signals to the earth. The GPS receives the information and determines the user's exact location, how the GPS finds the time remaining for reaching a certain destination is by comparing a signal
Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.
