GPS: Never EVER GET Lost!

By a smart 4th grader

Intro

Have you ever been lost?  Imagine you are hiking or sailing and you suddenly realize, you don’t know where in the world you are!  Your heart begins to pound.  Your forehead begins to sweat.  Then you smile and pull out your handy GPS. My report will cover three interesting ideas.  First, I will write about What GPS is what GPS dosed.  Next, I will cover The Invention of what GPS.  Finally, I will end with The GPS Satellites.

So, keep reading and let’s begin this journey about GPS.

What GPS is and what GPS does

This paragraph is about what GPS is and what it dose. GPS is just like a map except it is digital. GPS helps tell where you are. But it only works if you are in open space. Tom Harris said that A GPS receiver can help you find where you are, anywhere on earths, 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. The GPS was invented from the military army.  Allison K. Brown said that in the early 1970's, the military began developing GPS. It became fully operational in 1995.  (World Book Encyclopedia)

The GPS Satellites

       This paragraph is about the GPS Satellites.  The GPS Satellites has 27 but we only use 24. Marshall Brain taught that, the Global Positioning System GPS is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails).  (HowStuffWorks.com)

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 it dose.  Always remember the invention of GPS and the GPS Satellites.

 Thanks you very very much taking the time to read my report.
