GPS Navigation Devices work off the system of U.S. satellites to pinpoint geographic location. GPS stands for Global Positioning System, and was first used by the American military as a nuclear deterrent during the Cold War arms race. Ironically, it was during the Cold War that President Ronald Reagan, the epitome of a Cold Warrior, directed that GPS be made available for civilian applications following the Korean Airlines Flight 007 tragedy, one of the tensest moments in the entire 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 in the future.
GPS Navigation Devices can actually be traced back to World War II and the ground-based radio navigation systems developed during that time, such as LORAN and Decca. Today?s GPS allows 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). Generally speaking, GPS navigation devices are classified as civilian if it cannot be considered munitions, or weapons, by the U.S. government. For example, those capable of operating above sixty thousand feet at speeds of a thousand knots cannot be exported without special licenses. Otherwise, such GPS navigation devices can be easily installed in a ballistic missile.

The technology behind GPS navigation devices is made up of three parts. Most obviously, the satellite system needs to be in place. This comprises some twenty-four to thirty satellites in medium earth orbit. Then there is the control system, which is in turn composed of a master control station and an alternate master control station plus any number of shared and dedicated ground antennae and monitoring stations. Finally, the user component is simply all the individual end-users around the world, military and civilian.

GPS has become a global tool for the common good despite its military origins. Just like the internet, also originally conceived in response to war and the threat of war, GPS has grown beyond such narrow applications in death and destruction to the myriad of commercial, scientific, and recreational uses now available. Almost no aspect of our modern 21st Century lives are not touched by it, from the emergency rescue personnel dispatched to the conversations transmitted over cellular networks. GPS navigation devices have excelled properly and offer advantages to our modern society. Changing routes or finding shortcuts without a GPS can be difficult as well as frustrating, therefore different routes can be chosen in regard to the owner?s best opinion or whichever way is suitable for the circumstance. It is the number one choice for proper navigation.

When gamers look into upgrading their sound system to the highest quality, many decide upon getting a brand new surround sound setup. While this is a great, albeit expensive way of playing at times, there are times when it just won’t cut it. Sometimes you just need to isolate yourself from all annoying outside noises, or play through the night without bothering others with the in-game noise, or (most importantly to most gamers) you need to play online at a high level. When you are competing against others online you need the greatest tactical advantage possible. This is where gaming headsets come into the equation.

Buying the right pair of gaming headsets can make all the difference in succeeding in the online battlefield, and many can attest to this fact. High quality headsets, with Turtle Beach gaming headsets being the most popular, offer advanced precision surround sound where you can literally pinpoint exactly from which direction people?s footsteps (or reloads, or gun fire, etc.) are coming from and exactly how far away they are.

The fact is of all the gamers playing online, a very small portion have surround sound headphones, and therefore those that do have them have a large advantage over the competition. I can personally attest to this fact ? after buying a pair of Turtle Beach brand headsets, my kill to death ratio in Modern Warfare 2 honestly went from 0.97 to 1.15 after just three weeks of playing. You can hear enemies footsteps coming down a hallway or around the corner of a building and be right there waiting for them. They never know how you anticipated them with such precision. There is nothing more satisfying than doing this on a regular basis.

Having gaming headsets also greatly immerses yourself in the experience ? even more so than a pricey surround sound system. It is almost like listening to music with headphones or earbuds ? you are able to hear all the subtleties and nuances that you could never discern with normal stereo output. It is amazing when you first put them on and hear all types of sounds and audio cues that you never knew the game produced ? explosions are that much more intense, gunfire has so much more bite, and game chat is so much clearer than with default, low grade headsets.
