GPS: Never EVER Lost!

By a smart 4th grader and Mr. Welch

Intro

If you were lost what would you do? What if you thought and thought and thought but you still don’t have an idea. Just then an idea popped in your head. Then you pulled out your trusty GPS receiver. After that you were just fine.

My report will cover three interesting 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 think this was interesting, you must read on.

What GPS is and what GPS does

This paragraph is what GPS is and what GPS does.

A GPS is a handy little tool.  Some are as small as a cell phone.  It can tell you where you are on earth.  They are pretty cool. 

 Marshall Brain said that 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 GPS Satellites

This paragraph is about the GPS Satellites. 

What the GPS satellites do.

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 GPS and the GPS satellites.

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