LORAN EVALUATION TEAM

LORAN Evaluation Team

Background: The LORAN Evaluation Team was comprised of representatives from the U.S. Coast Guard, Federal Aviation Administration, the Volpe Transportation Systems Center, as well as academia and industry. The focus of the teams efforts were to determine if eLORAN could meet the nation’s navigation and timing needs. Specifically, the team conducted research and testing to determine whether an eLORAN system can provide the accuracy, availability, integrity and continuity:

  • To support lateral navigation through all phases of flight, including Non-Precision Approach (NPA)
  • To support Harbor Entrance and Approach (HEA) for maritime users
  • To support Stratum 1 frequency and precise timing users
  • To determine what other ancillary benefits can be derived from the continued provision of eLORAN services
  • To determine if providing these services via eLoran is cost-beneficial

The team provided its final report to the Department of Transportation in March 2004. The report and several enclosures are available below.
