CRADA2 Progress Report: New Timing Data Using eLoran

Our CRADA partnership with the Department of Homeland Security, Science and Technology Directorate (S&T), US Coast Guard (USCG), and Harris Corporation continues to yield very good timing data over long distances using eLoran.

During a presentation at the Institute of Navigation’s Precise Time and Time Interval (PTTI) conference in January, we showed results of using eLoran for timing as captured at several locations, including Leesburg, VA; Washington, DC; Boston, MA; and Bangor, ME. The timing data was gathered during periods in December 2015 and January 2016. A copy of the presentation is available on our website, entitled: “Providing Timing and UTC Service Using eLoran in the United States”.

As part of other on-air periods this year, team members UrsaNav and Harris were able to capture additional timing data, including from a new receiver located in Columbus, OH. This information is now available on our website, entitled “CRADA2 Timing Data Updates”.

Currently, we are using the former USCG Loran Support Unit in Wildwood, NJ as our primary eLoran transmission site. Over the next couple of months, we plan to bring the former Loran-C Station at Dana, IN on line as an eLoran site as well.

Our current timing receiver locations extend as far as 500 miles to the northeast of Wildwood, NJ and as far as 440 miles west. For the next test period, we plan to add timing receivers in Halifax, NS (700 miles); Dana, IN (675 miles); and Ocala, FL (800 miles). This will provide timing data at greater distances and over widely varying terrain.

Stay tuned to our website for ongoing CRADA progress reports. For more information on eLoran, please contact us at info@ursanav.com.
