GPS technology is an example of a rhyme of history. It rekindles using the stars and sun to navigate. GPS technology uses satellites positioned at different places in space to determine position and where your destination is and how to get there. Hundreds of years ago, people would use tools like the sextant to measure the distance between an object in the sky (like a star) and a point on the horizon in order to help them chart a course of travel. Similar to this method, GPS receivers measure distance using the travel time of the radio signals transmitted in order to triangulate and determine position and course. GPS technology is used in vehicles by drivers to navigate to different places as well as in cell phones for emergency purposes when 911 is called.

ReplyDeleteThank goodness for the use of GPS. Strange, I do not trust the technology 100%. I still travel with a map and print out the directions off of MapQuest. I read the signs and try to remember if the sun sets in the east of west. Do we really trust any technology 100%?

Sara,
ReplyDeleteI really enjoyed reading about the GPS and how people used the stars to travel in the past.I would also think that a GPS would rekindle a road map.

Sara,
ReplyDeleteI love my GPS for traveling, so I enjoyed reading your post. I also have a handheld GPS for geocaching, so I guess I enjoy using a GPS more then most people. What I can say is the area I live the GPS is not perfect, because it takes you down roads that are no longer there.
Hello Sara:
ReplyDeleteThank goodness for GPS technology. Scientists have made tremendous progress in improving navigational/travel methods. I can appreciate GPS technology because I am not very good at reading maps while traveling. I believe GPS prevents drivers from wasting time due to choosing incorrect routes and also stopping to read maps or ask for directions. Although drivers can purchase their own GPS, I believe every vehicle should be equipped with a state-of-the-art voice activated system.
