A Rare Think

The global positioning system (GPS) was first designed to aid military units at the height of the Cold War in the 1960s. Fortunately, for the last 30 years, the technology has been used in all sorts of applications. It will come as no surprise that a GPS is included in a range of items from cell phones to laptops. The flow of traffic in most modern cities would grind to a halt without the aid of GPS technology. Luckily, almost all luxury automobiles have a GPS device included as standard.

The most use of GPS is in navigation systems for land-based transportation, various types of aircraft and shipping. A sizeable constellation of solar powered satellites means that no matter where you may end up, with a simple device you can get a very accurate reading of your position. Drivers can use integrated or portable gps systems to follow a route, find other roads to circumvent traffic problems and with extra software loaded get live traffic info and gas station locations. GPS has benefitted an enormous range of people. Anybody needing to stick to a route (from pilots to truckers) or to reach a place or an individual (from explorers to fire-fighters) can use GPS to make their task less complicated. However, not all uses of pda phones are serious, geocaching is the most popular of these and is now played on every continent. The game is an advanced treasure hunt, which uses online co-ordinates to help the players track down a cache (which contains a log and a few items like geocaching coins or toys to trade). On the other side of the coin, GPS is a deadly serious matter. Fire fighters and ambulances make use of it day in day out not only to find the scene of an accident, but to travel there by the most efficient route. When something goes amiss at sea or if weather conditions deteriorate rapidly navigation systems will be literally a life-saver. Scientists and engineers also have uses for GPS software devices, in all sorts of experiments as well as monitoring just about everything on earth from tectonic plates to volcanoes. Even the movement of the continental plates and thunderstorms can be studied over time. In essence, GPS software can now be used to create very accurate maps.
