GPS: Never EVER Lost!

By a Fourth Grader

 

Intro                     


How would you like to receive a signal from a real live satellite from a GPS receiver you can!                                    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 the GPS.  Finally, I will end with The GPS Satellites.

This is such a good report you should keep reading.

What GPS is and what GPS does


This paragraph is mostly about what GPS is and what it does.

It looks like a cell phone. They can get to be very big and get to be very small.

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. 

Because lots of people were getting lost in the woods so if you were biking and you were lost then you could out a handy GPS receiver.

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 is satellites travel around the world twice a day.

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.”
