Candidate Coast Guard WADGPS Network Architectures

K. Tysen Mueller, John H. Kraemer, Joseph W. Spalding

Abstract:	The U.S. Coast Guard will &ploy a network of (50) DGPS reference stations by 1996 using the existing Marine Beacon network to transmit differential GPS corrections to marine users as part of a marine user DGPS service. The stations will provide coverage on the East, Gulf, and West Coasts, as well as the Great Lakes, Alaska, Hawaii, and Puerto Rico. Under a study funded by the DOT Volpe Center for the Coast Guard, the authors postulated and evaluated three candidate Wide Area DGPS (WADGPS) network architectures. These architectures would extend the DGPS service architecture to a proposed WADGPS service architecture. The criteria which have been used to evaluate these WADGPS architectures are: performance. integrity, reliability, and cost. To achieve the optimum performance, a new WA DGPS algorithm was developed and evaluated for use by two of the networks. The architectures for all three networks were also designed to be fault-tolerant
