Tactical GPS Tracking Systems ò€“ Location, Location, Location!

Although we might not realize it, GPS systems are all around us. GPS stands for Global Positioning System, which, as its name suggests, is a system that reveals the exact location of an object, provided that object has a GPS transmitter attached to it somehow. GPS works by performing GPS calculations using information provided by specially designated satellites. Transmitters in earlier GPS systems had to have a clear, unobstructed view of the sky. To a certain degree that is true in consumer navigational systems such as Tom-Tom or Garmin, as well as the GPS capabilities of most modern cell phones, but in commercial and tactical systems that is not necessarily the case. As research continues on improving GPS technology, more powerful GPS transmitters no longer need a direct view of the sky, which makes them very useful in covertly tracking a moving object.
