It provides jobs for millions of people, generates billions of dollars in worldwide revenues, and provides the basis for a multitude of related service and support industries. Automobiles revolutionized transportation in the 20th century, changing forever the way people live, travel, and do business The automobile has enabled people to travel and transport goods farther and faster, and has opened wider market areas for business and commerce. The auto industry has also reduced the overall cost of transportation by using methods such as mass production making several products at once, rather than one at a time ) mass marketing(selling products nationally and globally rather locally, and globalization of production (assembling products with parts made world-wide). Between 1886 and 1898, about 300 automobiles were built, but there was no real established industry. A century later, with automakers and auto buyers expanding globally, automaking became the worlds largest manufacturing activity, with more than 53 million new vehicles built each year worldwide Automobile manufacturers are among the largest companies in the world. These corporations are often multinational. These companies often share parts, or use parts made in foreign factories. The U.S. automobile industry produced 16.8 million vehicles in 1999.

GPS provides users with accurate information about their position and velocity, as well as the time, anywhere in the world and in all weather conditions GPS determines location by computing the difference between the time that a signal is sent and the time it is received. GPS satellites carry atomic clocks that provide extremely accurate time. The time information is placed in the codes broadcast by the satellite that a receiver can continuously determine the time the signal was broadcast. The signal contains data that a receiver uses to compute the locations of the satellites and to make other adjustments needed for accurate positioning. The receiver uses the time difference between the time of signal reception and the broadcast time to compute the distance,or range, from the receiver to the satellite. The receiver must account for propagation delays, or decreases in the signals speed caused by the ionosphere and the troposphere. With information about the ranges to three satellites and the location of the satellite when the signal was sent, the receiver can compute its own three-dimensional position As of March 1998, 24 GPS satellites were in operation. Replenishment satellites are ready for launch, and contracts have been awarded to provide satellites into the 21 century. GPS applications continue to grow in land, sea, air, and space navigation. The ability to enhance safety and to decrease fuel consumption will make GPS an important component of travel in the international airspace system.
