GPS Satellite
Some tech savvy and good gameplaying can come from a judicious use of the
new technology called the Global Positioning System (GPS), one of the
wonder technologies unveiled to the world stage during Operation Desert
Storm. The GPS traces its roots to the early 1960s. Yet it has proven to
be a prototypical 1990s dual-use technology. Both military and civilian
users can benefit equally from the accuracy with which the
satellite-based system can locate receivers on the ground.
As currently
comprised, the GPS contains 21 operating satellites and three in-orbit
spares. (New satellites are currently on the drawing board.) Each
satellite continuously emits a pair of high megahertz signals that
constantly interact to track down ground sites. These signals also make
it possible for computers to interact with each other and carry broad
spectrums of audio and video information.
