Default Gee after the cessation of hostilities

In among my pile of Cossor documentation I found this Gee Booklet.

It seems the wartime experiences were being pressed into civilian service.

I know very little about the operation of airports so I was curious was this system widely adopted?

I am guessing that this booklet was late 40's early 50's I don't see a date anywhere.

Who was this booklet aimed at?

I have roughly scanned it and put it into my drop box

https://www.dropbox.com/s/ylqqvth3f76f63d/Gee.pdf?dl=0

I have also put up a sample page.

I don't know if this document is available elsewhere.

Cheers

Mike T

I note from Wikipedia that stations in the North-Western chain for GEE post-war included those at Lowther Hill near Leadhills, Scotland (master), Great Dun Fell in the Pennines, Cumbria (slave) and Craigowl Hill (slave), above Dundee and a hop away from the Angus UHF TV transmitter.

I've been to Lowther and Gt. Dun Fell several times, as they both were used by the BBC for microwave link reserve feeds, and remember the old wooden transmitter towers up there. GDF and Lowther are still used today for modern CAA aviations RADAR but the old buildings remain, although none of the GEE equipment was around when I visited (that I knew of).

I never got to Craigowl Hill top but there were the remains of the accommodation block at ground level back in 1988 when I was attached to Forfar.

Fascinating!
Gee certainly remained in use by the RAF until the early 70s, the aircraft equipment post-war being Gee Mk3 which comprised a Receiver, Waveform Generator and Indicator
I wonder if this version actually went into service?

A few years ago I had a service visit to Trimingham NATS transmitter station on the East Coast. I was impressed by the original wooden mast structures still in use and dating back to some WW2 radar use. Whether Gee or Chain Home, I do not have a clue.

I have just found a 1954 Cossor pamphlet from the 1954 National Radio show.

On the Back is Cossor at Farnborough One of the products mentioned is a GEE MkIII Receiver. So it looks as if this was an on going product line.

As I'm reading Colin Dobinson's excellent book 'Building Radar', this thread resonates (!) nicely ...

(See you tomorrow, Andy )

This is what Gee Mk3 looks like, not the same as in this civilian version.

GEE was operational in the sixties from Worth Matravers (30.7 mc/s)

I'd imagine that Cossor were competing with Decca Navigator for the post-war nav systems market. After a quick look at the brochure I didn't see any marine applications which was an area where Decca made big inroads, lasting until the late 90s or even later, IIRC.
