Long Range Aid to Navigation
Decca was by the Brits .....
Loran C was by the USA.....
Both systems basically developed out of Wartime blind nav systems and bombing .....
Decca was more short range .... Loran C covered large expanses.
I hated Loran C at sea - as it was a knack of matching peaks etc.on a scope to get the time readout. Then plot it .....
Decca was easier - but lacked the range and coverage that Loran eventually had.
Decca was used by various ports to provide blind approach - that was how good it was ..... Rotterdam for example.
Loran was used by some of the Seismic ships - but ross checked against transponders such as Siledis etc.
Decca of course lost funding and was phased out. Loran was supposed to increase coverage to take in areas that lost Decca.... such as English Channel / Irish Sea.
If you want a Loran C set - I am sure that there are many that would gladly GIVE you one ....
GPS has effectively overturned the electronic nav world and old systems such as Loran are oft forgotten .....
Good riddance in my opinion to Loran ..... never did like it !!

Re: Long Range Aid to Navigation
But lets face it... you've not taken a fix until you've done so with a set of headphones, on, holding a square box in front of your face, watching a wildly gyrating compass and trying to get the loudest peep in your ear at the same time, while balancing on a violently moving deck..... anything within 10 deg was a result..... cocked hats... you could end up being miles out... ahhhhhhh those were the days!....

Had one of those, and threw it away cause it was less accurate than a good EP.

Re: what is - Loran \'C\' Navigator
Decca was very accurate & was very easy to use. The best bit about Decca though was two ships navigating in reduced vis/fog/mist/falling snow etc etc , going down the same position line, but in opposite directions!! Definitely brown trouser stuff & no mistake! It used to happen a lot on harbour approaches, if one of the position lines was in a convenient place & direction. A little like a stone age edition of GPS Waypoints, where everyone is heading to the same spot in the oggin!
Aaahh for the good old days!

Re: what is - Loran \'C\' Navigator
Decca was the British brilliantly over-engineered highly accurate largely manual local short range solution to navigation, Loran was the US global, practical, automateable, not so swiss-watch system that was utterly useable and thus superior in almost all uses. (eg; I never needed Decca to identify the corner of an oil rig to land on, Loran just took me to the rig - that was enough. Loran worked worldwide, Decca was very local indeed.
Compare this with Rolls Royce's magnificent V12 aero engines and the big smoky round things from Stateside. Which was technologically superior is in no doubt, but then neither is which commercially and practically ruled the global (air)waves for a decade or two. Swiss watches don't sell. Ask Swatch!
Decca (thank God) is dead, but now so too is Loran. There is little doubt as to which was more use to mankind.
Thank JC (Jimmy Carter) for GPS!
God I HATED those bloody spiders and cheeses, purple and red and blue parabola on distorted projection charts and all the cryptic indecipherable lanes and so on. Decca damn good riddance! Nothing was ever more confusing than that!
Thank Uncle Sam for GPS! Alleleujah!!

From a ship\'s PoV
Decca automated far better than Loran ...... Loran never caught on so well as Decca for coastal nav ..... witness :
North Sea
UK
Ireland
Canada
South Africa
Japan
Arabian Gulf
etc. etc.
It provided automated Port approach .....
The later sets were very good and also virtually removed Lane slip which was a pain in the early days .... which was the actual reason that following a lane was discouraged - not meeting another ship the other way - which of course is nasty !!!
When on Siesmic Ships - we used Loran to get out the shoot, used it to give nav on shoot - but it was shite ! compared to Siledis .......
You also have to remember that Loran was in 3 forms .... A, B and C ...... C being the one that prevailed far too long in my view !!
I actually feel sad that Decca faded away ...... especially that I bought a Decca set and then a few years later it was worthless !!! My set gave direct Lat and Long readout, was very accurate - subject to dusk and dawn effects of course ... and a small case long before Satnav reduced size !!
