Bletchley Navaids

26 February 2000 I've updated the page with a couple of links to other Bletchley Park sites. I think I might go and take a few more snaps of the present site so see what remains!

	Overall view of the navaids field showing most of the ILS elements
	STAN37 Localizer array... In practice a real one would have a parabolic (curved) reflector not a flat one
	View from rear of the Thomson-CSF 381T Localizer array, with the IRVR Dalek to the left
	Front view of the 381T Array from the front showing the loop elements
	Close up of a LLZ loop element
	Near-Field Monitor aerial for the 381T LLZ
	Glide Path Masts. STAN38 on the left, Thomson on the right.
	Glide Path Monitors. STAN38 on the left, Thomson on the right. The VOR array is in the background right.
	VOR (left) and DRDF (right) aerial systems.
	IRVR Dalek. Its opposite element is in the building !
	SSR Aerial Scanner...(Wide angle)
	...And Close-Up.
	AR1 scanner with the Navaids School in the background.
	Another view of the AR1. The Ocatagon contains the AR1 and Marconi equipment and classrooms on two levels.

Hope these are of interest to somebody now BP is a museum. The CAA stuff has moved to Highfield Park, just north of Basingstoke.

After seeing Enigma The Movie, I decided to make a return visit to the museum at Bletchley park. The navaids field is no more, having been sold off to make ends meet and will probably end up as yet another housing development.

	View of the now neglected site from the H-Block window.
	The once neatly-cropped grass is sadly overgrown.
	These views were photographed through a closed window as it is no longer possible to access the site.

For more details about Bletchley Park you might like to look at both of these excellent sites:
