Bedford, Massachusetts, USA. After extensive Final Acceptance Testing at Nautel’s Hackett’s Cove, NS facility, UrsaNav has accepted delivery of the first production NL40 Loran-C and Enhanced Loran (eLoran) transmitter. This seventh generation Loran transmitter technology is the culmination of over six years of collaborative development between the two companies.

The transmitter successfully met or exceeded all of the requirements of the U.S. Coast Guard “Specification of the Transmitted Loran-C Signal.” Testing was conducted into a simulated antenna matching the characteristics of a U.S. Coast Guard “standard” 625-foot Top-Loaded Monopole. The NL-Series transmitters are capable of transmitting Loran-C, eLoran, Chayka, and eChayka in any combination at power levels exceeding one megawatt. They are qualified for today, and prepared for tomorrow.

UrsaNav’s President, Charles Schue, commented: “Resilient PNT begins with complementary technologies, layered one upon the other in such a way that the user is ensured improved continuity of operations over a sole-source solution. eLoran is the terrestrial co-primary complement to GNSS, and our technology makes eLoran the most economical, efficient, and wide-area alternative when GNSS is not available.”

UrsaNav provides the world’s most advanced solutions for Low Frequency Alternative Positioning, Navigation, Timing, and Data, including high-performance eLoran Receiver, Command and Control, and Differential Loran technology. We are the exclusive, global, reseller of Nautel’s industry-leading, high-power, Low Frequency transmitters for Loran/eLoran and Chayka/eChayka.
