GPS is a satellite-based navigation system consisting of 24 satellites used worldwide to determine precise locations. It was developed by the U.S. Department of Defense and first launched satellites in 1974 for military purposes. GPS works by triangulating the distance and timing signals from multiple satellites to determine a receiver's position. It has many uses including navigation in vehicles, boats and planes as well as applications on smartphones.

 Features of GPS
 Uses of GPS
 conclusion

3.  satellite-based navigation
system
 constellation of 24
satellites
 Tracking device
 Helps us to show our exact
position on the earth
anytime, in any weather no
matter where you are.

4.  Developed by the U.S. D.O.D and Dr.
Ivan
 First satellite was launched in 1974
 For military purpose to have a

7.  Use to pinpoint any ship or submarine on
the ocean
 Find the way into cars, boats, planes
 To distribute accurate time around the
world
 Guide precision weapons to their target
 Measure heights of mountains
 Drivers can find out where they are if lost

8.  Here from the above discussion, GPS
is 24 satellite-based navigation
system which is a hacking device and
helps us to find the exact position on
the earth.
