Defining Enhanced Loran

In order to augment or back-up GPS, the performance, integrity and operations of existing LORAN-C systems are being enhanced in several areas of the world.  Yet the term “Enhanced Loran” has been used for years without a concrete definition.  In 2002 and 2003, the concept of Enhanced LORAN has received unprecedented attention in the US due to FAA and USCG Loran evaluation programs.  These programs plan to determine how LORAN-C will be modernized to meet the FAA’s RNP 0.3 requirements, the USCG’s Harbor Entrance and Approach requirements and to address time and frequency user needs. The issues of sole means vulnerability, homeland security, and the cost-effectiveness of Loran are currently being studied around the world, and answers from these FAA and USCG programs will be useful to all countries using GNSS systems.  The resolution of these issues will soon take form in new LORAN-C systems in various regions of the world.

The International Loran Association’s 32nd Annual Convention and Technical Symposium comes at an opportune time for a thorough discussion of Enhanced LORAN.  The components of Enhanced LORAN are being shaped through technology developments, implementation studies and experiments.  ILA 32 is an excellent forum to explore the progress to date and to facilitate an exchange of ideas as we near an initial definition of Enhanced LORAN.  With that goal, this call for abstracts is an invitation for papers focused on all aspects of Enhanced Loran. 

The 32nd Annual ILA convention will include sessions on all aspects of LORAN-C with an emphasis on topics relating to Enhanced LORAN-C.  Papers are invited and are especially welcome on system and governmental policy, operational doctrine, transmitting and user equipment, and new technology or applications.
