GPS satellite circle the earth twice a day in a very GPS satellite circle the earth twice a day in a very precise orbit and transmit signal information to precise orbit and transmit signal information to earth.GPS receivers take this information and use earth.GPS receivers take this information and use triangulation to calculate the user’s exact location. triangulation to calculate the user’s exact location. Essentially , the GPS receivers compares the Essentially , the GPS receivers compares the time a signal was transmitted by satellite with the time a signal was transmitted by satellite with the time it was received. The time difference tell the time it was received. The time difference tell the GPS receiver how far away the satellite is. Now GPS receiver how far away the satellite is. Now with distance measurement from a few more with distance measurement from a few more satellites, the receiver can determine the user’s satellites, the receiver can determine the user’s position and display it on the unit’s electronic map.position and display it on the unit’s electronic map.

CONCLUSIONCONCLUSION

The technology of the Global Positioning The technology of the Global Positioning System is allowing for huge changes in System is allowing for huge changes in society. The applications using GPS are society. The applications using GPS are constantly growing. The cost of the receivers is constantly growing. The cost of the receivers is dropping while at the same time the accuracy dropping while at the same time the accuracy of the system is improving. This affects of the system is improving. This affects everyone with things such as faster Internet everyone with things such as faster Internet speed and safer plane landings.Even though speed and safer plane landings.Even though the system was originally developed for military the system was originally developed for military purposes and it is used to support a broad purposes and it is used to support a broad range of defense.range of defense.
