GPS (Global Positioning System) was put into use by the U.S. in the 1960s as a military-use satellite-based positioning system. Part of the system was made available to the private sector free of charge in the 1980s, and the U.S. Department of Transportation was put in charge of managing commercial use. Military applications have remained under the control of the Department of Defense, but international coordination has been handled by the State Department. In a joint declaration made in 1998, Japan announced its intention to cooperate with the U.S. in its use of GPS. Tokyo's plans to increase the accuracy of GPS readings involve launching three quasi-zenithal satellites. These satellites will be operated so that one will always be traveling over Japan. By complementing readings from the U.S. GPS, the three satellites are expected to sharply improve the accuracy of location information.
