The ROMY is around the length of a telephone pole on each of its sides.

That’s not very helpful.

I may have mentioned this before, but education for engineers and scientists in the UK has been entirely metric since 1967.

That’s 53 years ago :)

But 30ft (9m) would be a good average pole

This is essentially a big optical gyroscope. These have been around for many decades. By using a coil of optical fibre rather than just mirrors like this the whole installation can be shrunk enormously.

I wanted to see optical gyroscopes used instead of mechanical gyroscopes on the Hubble spacecraft, remember how the mechanical gyroscopes kept failing, and not just on Hubble. But back in 1990 the accuracy of optical gyroscopes was not good enough for that use.
