As I understand it, NATS and BAA were unable to reach agreement on renewal of the lease for the current Central Area radar site.

So it gets decommissioned and they build a new one from scratch.

Probably makes perfect sense to some bean-counter somewhere ...

The 23 presently on T1a car park would be owned by NERL whereas the ASR10 (10cm) located near T4/Holiday Inn would be owned by HAL (although probably maintained under contract by NSL); could there be a bit of jealousy there I wonder?

Presumably then chevvron, the 10cm is the main radar for EGLL Approach?
It would be interesting to know what radars have been sited at Heathrow over the years, and what they were used for. Shame the HSA 23cm will be going, like the old tower, it's a fairly iconic part of the airport's landscape.

As all radars are used at Swanwick, I would assume both radars would be available to Heathrow Approach/director etc but they may be 'mosaiced' together.
My own experience on Farnborough LARS North meant I was able to assess both of them and I personally found the Heathrow 10cm had better coverage for the LARS task to north and northwest than the 23 cm, whereas Debden 23 cm was superior to Stansted 10cm for coverage to the north east - you could see traffic almost at ground level at Wyton on the Debden 23 but not the Stansted 10.

Chevron,

Both H23 & H10 owned and maintained by NATS. The reason for moving away from LHR was that BAA wanted the land that H23 stands on back to develop it and there was no alternative on offer.

<<Presumably then chevvron, the 10cm is the main radar for EGLL Approach?>>

The 23cm used to be the primary approach radar with others, including the 10cm, as "also available".

Someone been watching Only Fools and Horses?

Absolutely, now what will the news crews use for their "LHR related story" backdrops. :E

Much rather have replaced H23 in situ.....life would be a lot easier!

Demolishing the concrete plinth without collateral damage should be an interesting exercise.

It's a pity Fred Dibnah isn't with us any more ...

Sadly, I can remember a time before it was there...

Originally it was on top of one of the BA car parks on the east side.

Nah, different head.
The CP was the six-fifty. Lousy radar. Didn't last long.
Before the HSA23 we had 264E/W/T, 232 and that ACR6 thing...4008?

And before that the real ACRVI and S264..

The Radar that's gone missing from the grounds of what was the then CAA's TEE (Technical Engineering Establishment) was the TSF (Training & Support Facility) for the HSA 23cm radars.

The last of these 23cm Radars is at Heathrow and because of all the cranes being used there at the moment it's not used operationally too much.

The new radar at Bovingdon will replace H23 completely and is due to come into service soon, as is the new 10cm Radar at Gatwick as soon as all the teething troubles are sorted.

ittbf
 

"Switch it off.......!!!!!!!!!!"

The new Gatwick Radar is in service now.

but used by Swanwick presumably.

HD correct, but also used as the main ATM feed to the tower.

Ahhh.. forgot that. Thanks.

Now boys take off your Anoraks, brush your teeth and straight off to bed.

And no naughty dreams about wave guides :eek:

Nite nite, SGC
