GPS: Never EVER Lost!  

By 4th grader and Mr. Welch


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 and what GPS does.  Next, I will cover the invention of 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 GPS is and what GPS does

GPS is a satellite ran system it can tell where you are only out side. And that is what it is and what it does

Marshall Brain 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 army for the army invented GPS. It was invented in 1970’s. That’s what I know but I bet I could come up with more. Will that’s it for The Invention of the GPS goes to The GPS Satellites.

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 satellites are the main reason why we have GPS the satellites can use a fancy math to know where you are all the time that’s why you never get lost with a GPS

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).



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.
