Maritime Differential LoranÕs Major Step Towards System Integration

Anthony Hawes, Kevin Carroll, Benjamin Peterson, Kenneth Dykstra

Abstract:	"For the past three years the U. S. Coast Guard and Federal Aviation Administration has cooperated in a critical effort to evaluate the new Enhanced Loran-C as a backup to GPS-provided services in positioning, navigation and timing. Each agency has defined the requirements that Enhanced Loran must meet to be considered a GPS backup and, more importantly, shown the systems work during proof-of-concept testing. Recently, the efforts are now focusing on development from initial concept to full implementation procedures. The Loran Support Unit (LSU) is leading a project to develop the technical procedures and guidelines for surveying a harbor and using Enhanced Loran to achieve Harbor Entrance and Approach navigation accuracies. This paper discusses the system integration of different research aspects into one comprehensive system for navigation within a port. The Port of Boston was selected in the summer of 2004 to be the test port to integrated shore monitor, survey grids and broadcast signal corrections in real-time. A monitor site was installed and the signal performance data collected over the four-seasons is presented. An analysis of the past surveys is given."
