GPS: Never EVER Lost!

By 4’Grader and Mr. Welch

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 it does.  Next, I will cover The Invention of the GPS.  Finally, I will end with The GPS satellites!

Mr. Welch’s Keep Reading Statement: 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 does!

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!

The Invention of the GPS

This paragraph is about the invention of the GPS. 

The Army invented it so they wouldn’t shoot their own people, and so they wouldn’t get lost!

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.

4’Grader


The GPS satellites can go around the earth 3 times in one day; they also are about 4000 pounds each. There are 27 satellites but 3 are for backup incase one fells!

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, 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 what GPS is and what it does.  Always remember the invention of GPS, and The GPS satellites!

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