The first navigation aide I used was Loaran A.

You used an Oscilloscope to find bearing numbers that were represented on nautical charts with lines Correlating to North South and East West.

It was time-consuming and not terribly accurate.

Eventually the scopes were replaced with vacuum tube digital read out machines that gave us actual numbers that could quickly be found by on the chart.

In the mid 70’s Texas Instruments developed next generation Loran C.

They set a temporary tower set up on Cutty Hunk Island and positioned a ship offshore where-by they could calibrate and test the new system over the Nor’east coastal waters.

This was a huge step forward in reliable navigation aides to mariners.

The nautical charts of this time had 4 sets of lineson them Lat/Long and Loran.

Lat/Long lines on the charts were straight upand down but the Loran lines swept across the chatrs in a curving, broadening arc emanating from the towers that transmitted the signals which correlated to numbers depending on your position and distance from the towers.

This system reduced the numbers of navigational accidents and saved untold numbers of lives and vessels from dissaster.

Now that GPS is de-classed the Loran system has been shut down and the towers have mostly come down.

Personally I think the Loran system should have been kept in place because if GPS goes down most of the people who sail the oceans today will be totally lost.

It was a good primary in it’s dayand would still be a great back-up today.

I’m guessing that one of these days one of those brothers with size 3 feet is going to run into the wrong person and catch a fucking beating. Who knows?

I’m not suggesting it happen, but I won’t be surprised if it does!
