5G and GPS
 

Following article will explain why commercial pilots are concerned about GPS.
There is a push by the govt. to do away with Lorance and 'sell' the wavelength to the communication giants. Without Lorance and diminishing GPS accuracy a disaster is waiting!

What is Lorance?

Here is an article that actually explains some of the issues in regards to the 5G networks (the proposed Ligado network specifically) and GPS frequencies.

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.

You are correct! I just did a bit more reading on Loran (its been a long time!) It was Loran-A that was decommissioned in the 80's.

I can't speak on behalf of the armed services side of things, but celestial navigation is still very much a part of the curriculum required by many of the USCG issued Merchant Mariners licenses.

I'm sure that the USN surface folks still practice cel nav, but it's been long gone from the aviation part of the Navy.

Gone, But Not Forgotten...
 

Something VP-11 should know something about?

I don't know; should someone from the Proud Pegasus ranks know what "Lorance" is?

I used to work for THE company that designed and manufactured the Loran-C transmitters for the US coast guard (and other countries).

I spent 6 months in Egypt installing a system for traffic control. I'm sure now that's all gone to GPS. I only mention this due to the recent news about the Suez being blocked by the container ship. I spent many days driving up and down the length of the Suez back in the day.

I started at the company as a technician and ended up developing their software for remote control of the Loran-C transmitters, etc.
