Navigation On The Road: The GPS
GPS navigation devices work off the system of U.S. satellites to pinpoint geographic location. GPS stands for Global Positioning System, and was initially used by the American military as a nuclear deterrent throughout the Cold War arms race. Ironically, it was throughout the Cold War that President Ronald Reagan, the epitome of the Cold Warrior, directed that GPS be produced available for civilian applications following the Korean Airlines Flight 007 tragedy, one with the tensest moments inside the whole Cold War. This incident occurred when a Boeing 747 strayed into the airspace of the now-defunct Soviet Union and was shot down, killing all aboard, including a sitting United States Congressman. Investigations concluded that a navigational error was to blame, and tracking procedures were changed in order to avert similar accidents within the future.
GPS navigation devices can really be traced back to World War II as well as the ground-based radio navigation systems developed throughout that time, such as LORAN and Decca. Today’s GPS enables soldiers get their bearings in the dark as well as unfamiliar territory, provides tracking information on potential targets, guides missiles and bombs, and even helps in the creation of reconnaissance maps. Civilian applications include land surveying and time transfer (synchronization of clocks). Usually speaking, GPS navigation devices are classified as civilian if it cannot be considered munitions, or weapons, by the U.S. government. For instance, those capable of operating above sixty thousand feet at speeds of a thousand knots can not be exported without having special licenses. Otherwise, this kind of GPS navigation units can be easily installed in a ballistic missile.
The technology behind GPS navigation products is made up of three parts. Most obviously, the satellite method needs to be in place. This comprises some twenty-four to thirty satellites in medium earth orbit. Then there's the handle system, which is in turn composed of a master control station and an alternate master manage station plus any number of shared and dedicated ground antennae and monitoring stations. Finally, the user component is merely all the individual end-users around the planet, military and civilian.
GPS has turn out to be a global tool for the frequent excellent despite its military origins. Just like the web, also originally conceived in response to war and also the threat of war, GPS has grown beyond such narrow applications in death and destruction for the myriad of commercial, scientific, and recreational uses now obtainable. Almost no aspect of our modern 21st Century lives aren't touched by it, from the emergency rescue personnel dispatched for the conversations transmitted over cellular networks.
