The chief aim of this article is to discuss about global positioning system. Maybe even more admired than satellite phones is GPS technology. GPS, which stands for Global Positioning System allows users to decide where they are, frequently within a dozen feet or so, immediately devoid of having to use a compass and create difficult calculations. This method is based on signals that come from satellites in geosynchronous orbit around the Earth, so the signals are accessible just about anywhere.
