OP: Most people don’t stop to think how dependent they have become on GPS technology. GPS technology is already incorporated into many ubiquitous services that are taken for granted, with increasingly more applications leveraging it. Power grid nodes are one example. They partially rely on GPS atomic clocks for the power grid networks synchronization. The same applies to the cell phone towers and real-time financial markets transaction services.
Another interesting example is the Automatic Identification System (AIS) used for tracking ships at sea. As part of its service, it relies on GPS to determine the location of a vessel.
