CRAC Goonhilly Visit

As arranged we all congregated at the approach to the
main gate at Goonhilly and at around 19.05pm
Anthony Sutton arrived and enquired if all were present.
Those missing from the list were Peter G3WKP
and Dennis G7AGZ [he was unsure of attendance]
so it was decided to proceed.
Anthony talked at some length about the position Goonhilly
has found itself in with the loss of it’s contract to service
marine & Aeronautical communications to a site in the
Netherlands it soon became clear that on pure financial grounds
that satellite operations would be based at Madely from now on
and GH would be shut down. Decisions on the future are still
being considered wioth several options being looked at. The dishes
are, it is hoped either going to be sold or leased but if not by
September scrapping is likely to go ahead.
Aerial 1 will of course remain as it forms an integral part of the
visiter centre and is still capable of working operationally.
It was in around 1962 that the first reception was tracked
across the sky from the low earth orbit satellite Telstar.
Following that the Early Bird satellites came on stream and
subsequently, the satellites have become Geo Stationary
and need far less tracking. As with all forms of communication
times have moved on and now, massive bandwidths are
available by using Fibre Optic cables and the network of these
is now global in nature rendering the satellite dish virtually redundant.
Goonhilly has a period of some 10 years before the last of it’s
international cable operations comes to an end and there is still
an under sea cable linking to the Channel Islands to look after.
Also the BT fault diagnostics center is based here and at Edinburgh
so still a working establishment for the forseeable future although
the skyline is certainly going to change in the not too distant future.
The tour of what was left of the electronics and control functions
was fascinating and then we went intoAntenna 3. This is a 1970’s
[I believe] structure and the pictures show it from almost all angles.
Once inside it becomes all to apparent how large the structure actually is.
Certainly, with the equipment moved out it would be large enought to
become a family home, strange shape but never mind.
Taking the lift we went up to the business end of the dish and examined
the final piece of equipment that passes the TX signal to the dish
[see photo’s]. Anthony described the way this all worked and after,
Mark explained in some detail to Chloe what it was all about
[another Dr Vaughan in the pipeline I think]
Back outside to take a few late pictures as the sun had by
then dipped below the horizon.
Excellent couple of hours. We took the opportunity as this was
certainty a lash chance saloon situation, another 12 months and
it could all be gone save antenna number 1.
Thanks Anthony, much appreciated by all of us.
