The medium I chose to do was GPS which is short for Global Positioning System. This technology was first developed in space, it gave astronauts an extremely accurate information regarding their exact location and time in the location. It allowed them to navigate space and earth easily and efficiently. This technology is based off of satellites and is controlled by the U.S. government. This technology fifteen years ago was only available to NASA but now it is available to anyone with a GPS receiver or what most people call a navigation system. The first people to introduce this to the public were car companies and with this technology the companies were actually able to locate you and know exactly where you are. The plus side to this was with a feature called ONSTAR which was developed and is exclusive to General motors auto company they were able to know if you got into an accident and call you through your car to ask you if you were ok which has saved many lives. This GPS technology is not only helping people navigate roads around the world but it is saving the lives of drivers and keeping america safe by allowing the military to locate the enemy and in some cases not have to be present in there location to attack them which I find pretty amazing. GPS is currently expanding more and more as we are now able to get it on our phones computers and cars.
