GPS: Never EVER Lost!

By: A forth Grader

Intro

How would you like to receive a signal from a real, live satellite? With a GPS receiver, you can!

My report will cover three interesting ideas.  First, I will write about what GPS is and what GPS dose.  Next, I will cover The Invention of the GPS.  Finally, I will end with The GPS Satellites.

If you liked it so far you must read on.

What GPS is and what GPS does

  This paragraph is about what GPS is and what GPS dose.

 

 GPS is a handy little tool. Some are as small as a cell phone.

Marshall Brian said that

A GPS receiver can help you find where you are, anywhere on earth, as long as you has 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. 

GPS was invented so you will not get lost.

5Allison 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 give the GPS receiver the signal so you know was you are.

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 want to receive a single from a satellite then get a GPS.  I hope you enjoyed learning about GPS.  I know I enjoyed learning about what GPS is and what GPS dose.  Always remember the invention of the GPS. And the GPS satellites.

Thanks a lot for reading my report I hope you like it.
