Latest Advancements In Electronics
Today, things are much easier thanks to Latest Advancements in Electronics. A pocket-sized gadget, or even certain mobile phones, can tell you exactly where you are on earth atany moment. As long as you have one of these technological marvels and a clear view of the sky, you’ll never be lost again. Consider some of the extreme measures our predecessors took trying to prevent this predicament: they read the stars, erected monumental landmarks, and spent ages drafting detailed maps.
The marvel, of course, is the GPS, or Global Positioning System, an interlinked constellation of up to 30 earth-orbiting satellites, originally developed and implemented in 1960 by the United States Department of Defence. In 1983 President Ronald Reagan issued a directive making GPS freely available for civilian use and it became operational in the same year. When people talk about a GPS, they usually mean a GPS receiver, or a Personal Navigation Device (PND).
