GPS: Never EVER Lost!

By Nick Porter and Mr. Welch

Intro

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

My Conclusion

In conclusion, [Mr. Welch’s Attention Getter Follow-Up: 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 [1st Main Idea].  Always remember [2nd Main Idea] and [3rd Main Idea].

[Mr. Welch’s Thanks For Reading: Thanks a lot for taking the time to read my report.]

 

 Report will cover three interesting ideas.  First, I will write about What GPS in anSd what GPS dose.  Next, I will cover The Invention of the GPS Finally I will end with The GPS Satellites.

 If you think this is interesting then read on.

What GPS is and what GPS does

 GPS is a handy little tool some are as small as a cell phone or they can be big to. It can tell you where you are on earth its pretty cool. Marshall brain 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 was made for the army so soldiers would not get lost.

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 use 3 to find the 4th

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.”
