NASA, declaring "For the Benefit of All," moved quickly, launching the Explorer 1 satellite on January 31, 1958. Led by the former head of the German rocket program, Wernher von Braun, NASA immediately began to explore the possibility of sending human beings into space. Dubbed Project Mercury, this program involved seven original astronauts, of whom, Alan Shepard became the first American into space, while John Glenn would become the first American to orbit the earth.

But this did not mean we had achieved space supremacy. With the Space Race underway, NASA began implementing a new tracking system, called the Global Positioning System (GPS). The system involved the use of satellites to track the position and location of both spacecraft and intercontinental ballistic missiles. Initially developed by the Navy, the first successful GPS tracking system was dubbed Transit, and used five satellites to triangulate positions around the globe.

Though GPS systems had been used exclusively by the military and government, all that changed in 1983. In that year, a Soviet interceptor aircraft shot down the civilian Korean Air airliner KAL 007, killing all 269 people on board. The plane had strayed into Soviet airspace and although the Soviet had probable cause to destroy the perceived threat, it was determined had the airliner had accurate navigational systems, the tragedy could have been avoided. President Ronald Reagan subsequently announced that civilians and civilian agencies should have access to the GPS tracking systems.

GPS systems have become integral components of modern American life. From the Space Race to racing down the highway, a GPS system is guiding us. Not only has it become the preeminent navigational system for cars, but the scientific community has used it to track wild and domestic animals and migration patterns. Law enforcement uses GPS tracking to find stolen cars and keep tabs on criminals on bail or probation. Now, not only can someone find where they are on a city grid, but also he or she can find nearby businesses and restaurants. The uses, and the wonders, never end.

If you are keen on finding a reliable GPS tracking system, you need look no further than outer space -- and the Internet.

The GPS system was developed exclusively for and by the United States military. In'83, however, after a Korean flight was shot down by Russia for being in the wrong airspace, Ronald Reagan made it available to the masses. He believed that the world needed this technology in order to avoid disasters like the Korean flight. Since then, it has evolved into much more than a military device.

The theory behind global positioning is simple, but its implementation is rather complex. The U.S. government has approximately 30 satellites in orbit at any given moment. These satellites send out a constant stream of microwave signals back down towards the earth. A GPS tracking system on the ground receives the signal from the satellite. It then calculates the exact position, direction, and speed of itself based on these signals. Each time the receiver gets a signal from the satellite, the new calculations are made immediately then relayed as coordinates.

Today, a great number of cars are equipped with GPS tracking systems. They tend to be reasonably priced and easy to install. They can all provide turn-by-turn directions to any contiguous location. Most are even voice enabled, telling you to "turn at the next right" so you can keep your eyes on the road and hands on the wheel. One of the newest devices to get GPS capabilities is the iPhone. Having detailed maps in your cell phone opens up a world of possibilities for everyone.

Indeed, GPS is extraordinarily useful. To say global positioning technology is useful is about as insightful as saying a hammer is useful. If you're lost, you will certainly be grateful for it. GPS devices are affordable conveniences that are now poised to become as ubiquitous as hammers. Navigate your way home, no matter where life takes you.

Drivers, guardians, and companies that need GPS tracking systems as a matter of course are encouraged to get the right model for the right occasion. Visit the Uber Article Directory to get a totally unique version of this article for reprint.
