IntroductionGPS Global Positioning SystemIt provides information on location (longitude, latitude and altitude) and time in all weather conditions , anywhere on the earthTo gain a great accuracy using GPS there must be an obstructed line of sight to four or more satellites

History Of GPSGPS idea came out from the ground based radio navigation system in 1940s by British Royal Navy during World War II.

Later it was developed by United States government and freely accessible to anyone with a GPS receiver.

In the figure at left, the dotted lines show the actual intersection point, and the gray bands indicate the area of uncertainty.In this diagram, the solid lines indicate where the GPS receiver "thinks" the target is located. Because of errors in the receiver's internal clock, these spheres do not intersect at one point.

CONCLUSIONGPS GUIDED WEAPONS ARE NOT AFFECTED BY HARSH WEATHER CONDITIONS OR RESTRICTED BY A .WIRE, NOR DO THEY LEAVE THE GUNNER VULNERABLE FOR ATTACK.
