How would you like if you were camping and started panicking then you remember your GPS.
My report will cover three interesting ideas. First, I will write about what GPS and what it does. Next, I will cover the invention of GPS. Finally, I will end with the GPS satellites.
Keep reading to find out more!
This paragraph is about what GPS is and what GPS does.
GPS is a little tool. Some are smaller than a cell phone.
Marshall brain said that
A GPS receiver can help you find where you are, anywhere on earth. 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 reason GPS was invented it so in the army so people don’t get lost and so they don’t shoot their own people.
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.
So if you were in a building with thick walls it would get lost.
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.”
In conclusion, so if you are skiing and get lost you need a GPS. 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.
