THE LORAN RECAPITILIZATION PROJECT

摘要

An enhanced and upgraded Loran-C System, with Loran Data Channel, would be the only GPS augmentation system with the capability to provide independent positioning and timing during outages of GPS service. The Loran "upgrade and modernization" efforts began in 1997 at the U.S. Coast Guard Loran Support Unit following the signing of a Federal Aviation Administration (FAA)/U.S. Coast Guard (USCG) Interagency Agreement. The formalized Loran Recapitilization Project (LRP) effort began in FY 2000, with the goal to modernize the North American Loran-C radionavigation infrastructure in order to reduce total ownership costs and better meet critical availability, accuracy, integrity and continuity requirements. Manpower intensive legacy timing, transmitting and monitoring equipments are making way for equipments that may allow the Coast Guard to reduce or completely eliminate personnel at the Loran Transmitting Stations. The new equipment will greatly reduce required maintenance, and eventually allow for outsourcing the entire maintenance, operations, training, and depot repair for the entire USCG Loran-C System. This presentation outlines how we expect to meet the goals of increased maintainability, lowering total ownership costs, while better meeting required availability, accuracy, continuity and integrity, and provides the status of major LRP subtasks.
