[Boatanchors] Loran C

[Dave Roscoe]

Dear Keith:

I will do what I can to share with you whatever knowledge I have retained
re Loran C systems, from US Navy ET School training in 1953,  51 years ago !

Loran C is a nav system , that utilizes a technique of measuring the time
difference  in the reception of 2 radio signals , one from a master
transmitter, and another from a slave transmitter that transmits a finite
known time after the master transmitter.  The locus of a constant time
difference results in a series of hyperbolic curves  , when plotted on a
chart . Measuring  the time difference from another transmitter pair,  and
finding the intersect point of those 2 curves, results  in an accurate LAT /
LONG position. Atmospheric conditions caused significant errors frequently.
I believe , for that reason and others,  that this system has not been in
use for many years,  superceded  first by Loran A , and more recently by GPS
satellites .

Perhaps others on this list , with more definitive knowledge may chip in
with corrections or additions.   Remember  , this is from 51 years ago and I
have done my best.

It is a Furuno LC-80.
