By: a smart 4th grader and Mr. Welch

Intro

What if you get lost and you do not know wear you are then you remember that you have a GPS in your pocket.  My report will cover three interesti

ng ideas.  First, I will write about what GPS is and what GPS does. Next, I will cover the invention of the GPS.  Finally, I will end with the GPS satellites.  If you want to learn more about GPS read on.

What GPS is and what GPS does

This paragraph is about what GPS is and what GPS does.  GPS is a handy little tool.  Some are as small as a cell phone

Marshall Brain said:

A GPS receiver can help you find where you are, anywhere on earth as long as you have a clear enough view of the sky. If your GPS receiver can get signals from 3 or more satellites, it can figure out where you are by doing some fancy math called trilateration.

 

The Invention of the GPS

This paragraph is about the invention of the GPS. Allison K. Brown said that

In the early 1970's, the military began developing GPS. It became fully operational in 1995.

The army invented GPS. Soldiers kept getting lost. So, they   invented something that would identify where on earth you were. 

This paragraph is about the GPS Satellites

Digital Graphic Research Corporation taught that,

“A GPS can get lost if it can't hear the tunes. Radio waves travel in straight lines, and they don't pass through metal or rock easily. So in a tunnel, or downtown surrounded by tall buildings, or even under heavy tree cover, a GPS can lose its position.”

 

Conclusion

In conclusion, If you never want to be scared by getting lost, be sure to have a GPS. I hope you enjoyed learning about GPS.  I know I enjoyed learning about what GPS is and what GPS does.  Always remember the invention of the GPS and GPS satellites

Thanks a lot for taking the time to read my report.
