GroundBound....
Actually I think that there are some "off the shelf systems" that might work for Swanwick.
The kit at Brest is pretty good (Thomson CSF as I recall), and the stuff at Maastricht looked good the last time I visited.. It's been updated since I think. Amsterdam has system that works and our dear colleagues in the USA at least have nice big colour displays now.
For a system that works just look "next door" at TC. NODEL isn't perfect, but is a darn sight better than the ergonomic nightmare that LATCC AC has to offer and, it has a PROVEN track record of reliability. Oh, it's also available, right now.
Personally I think that this "evolutionary" step to NODEL is the way we should have gone, rather than the "big bang" complete system change that NERC has been.... too late now..
