DOT: Support to the GPS User

Rebecca M. Casswell, Hank Skalski

Abstract:	The Global Positioning System (GPS) is now an integral part of information technologies that are fundamental to modern life. The President and Congress have both directed the U.S. Department of Transportation to be the civil lead in GPS management and to be the stewards of the system for the civil community. This paper will briefly describe the history and the methods DOT uses to perform that role, as it bridges the gap between GPS management, system operations, and the user community. Users of global satellite-based positioning, navigation, and timing services need current, real-time information and support that promotes the efficient performance of daily and future applications. To this end, the authors will also examine some of the current issues faced by the civil community, identify the near-term methods of addressing those issues, and describe the plans to meet future user requirements. Those issues include but are not limited to, user input for continued system operation and modernization, the reporting and resolution of intentional and unintentional interference, and the dissemination of GPS operational information.
