I think broadhopper may be mixing up the name. Lowrance is a marine electronics company which is still in business. Loran was a "long range" radio based navigation service which was decomissioned by the USCG in the late (I believe) 80's, and globally shortly after. I believe, however, they may be referring to the L-Band carrier frequencies that GPS operates on.
The USCG turned off U.S. based LORAN-C transmitters in early 2010. I was taught the use of LORAN while in USN Naval Flight Officer training on T-43 aircraft. This was in the late 80s, and a lot of what we learned then has not been a part of the syllabus for years, maybe decades, including day and night celestial navigation (just a bit less precise than GPS). I was wondering if BroadHopper was referring to LORAN-C, which wouldn't make much sense in the given context, or something else.
