Augmented GPS - The Federal System

James Arnold, Robert DeBolt, Sally Frodge

Abstract:	This paper describes a study, recommended in the Report of the Joint DOD/DOT Task Force, The Global Positioning System: Management and Operation of a Dual Use System, to develop a recommendation for an optimum integrated system to provide Global Positioning System (GPS) augmented services to the Federal government. Additionally the study will recommend a transition plan, if needed, to implement such a system. The conclusions and recommendations of the study will provide an independent expert opinion to the Department of Transportation (DOT) to assist in its determination of which GPS augmentation(s) it should continue to support and implement. Factors bearing on the determination of which GPS augmentation(s) to be supported and implemented are: ability to meet user requirements and needs of the operating administrations and other users; cost of Federal development and deployment; user cost; effect on proliferation of government funded GPS augmentation(s); and the ability to satisfy the national security requirements regarding hostile exploitation of augmentation services. This study may also be used to provide guidance and recommendations, where appropriate, to other Federal agencies which are investigating the use of, or are operating, GPS augmentations. Oversight of the study is provided by a Study Review Board (SRB) consisting of senior level officials from the DOT, Department of Defense (DOD), and the National Oceanic and Atmospheric Administration (NOAA). The study is being managed by the Federal Highway Administration (FHWA) through an Inter- Agency Agreement with the Institute for Telecommunications Sciences (ITS) of the National Telecommunications and Information Administration (NTIA). The role of each of these organizations is discussed and the involvement of additional organizations is described. The study objectives and potential impacts on current Federally funded augmented GPS systems will be addressed as well as the systems application to current initiatives such as Intelligent Vehicle/Highway Systems (IVHS).
