Look up in the sky. What do you see? Clouds, maybe a plane or two? On a field trip to Utah Valley University Mr. LeMmon's Honors World Civilization class learned it is much more than that.
If you could see 6,000 times the distance you do now, you would be able to spot the multimillion dollar devices that, with a GPS, can pinpoint your exact location in just seconds. Satellites send signals down to earth giving you your longitude and latitude. This can help you find other locations and directions to get there.
